1.1 Fundamental safety instructions
1.1.1 General safety instructions
WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or severe injury.
● Only work on electrical devices when you are qualified for this job.
● Always observe the country-specific safety rules.
Generally, the following six steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any of
the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse sequence.
WARNING
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may
carry a hazardous voltage that might result in serious injury or death.
● Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV-
(Protective Extra Low Voltage) output voltages for all connections and terminals of the
electronics modules.

WARNING
Electric shock due to equipment damage
Improper handling may cause damage to equipment. For damaged devices, hazardous
voltages can be present at the enclosure or at exposed components; if touched, this can result
in death or severe injury.
● Ensure compliance with the limit values specified in the technical data during transport,
storage and operation.
● Do not use any damaged devices.
WARNING
Electric shock due to unconnected cable shields
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
● As a minimum, connect cable shields and the cores of cables that are not used at one end
at the grounded housing potential.
WARNING
Electric shock if there is no ground connection
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when touched,
can result in death or severe injury.
● Ground the device in compliance with the applicable regulations.
WARNING
Spread of fire from built-in devices
In the event of fire outbreak, the enclosures of built-in devices cannot prevent the escape of
fire and smoke. This can result in serious personal injury or property damage.

1.2.2.3 Cooling
To calculate the heat dissipation, the total power loss PVtotal of all heat-generating components
in a housing must be taken into account.
Total power loss PVtotal = PV1 + PV2 + PV3 +... [W]
Convection surface area A [m2]:
The surface areas of the front and bottom sides are not included in the convection surface area
calculation.
Note
A recommended value for the power loss of the operator control components is contained in the
"Technical data" section of the associated component (see "Power consumption").
Means of heat dissipation
Heat dissipation can take place as follows:
● Heat dissipation by natural convection
● Heat dissipation by natural convection and internal air turbulence
● Heat dissipation by open-circuit cooling
● Heat dissipation by open-circuit ventilation

Fan design
● The fan must be positioned to produce an optimum heat dissipation. A clearance of 10 mm
must be maintained in front of the fan.
● The inlet and outlet slots must remain free for the open-circuit ventilation.
● Air filters must be provided to maintain the permitted environmental conditions.
NOTICE
Damage to the operating components caused by temperatures that are too high or too low
Contaminated air filters impair the desired heat dissipation. For handling the air filters, pay
attention to:
● Proper handling
● Regular replacement
● Correct disposal

Guidelines
If the convection area A [m2] does not suffice for the "heat dissipation using natural convection",
then use:
● "Heat dissipation using natural convection and internal turbulence" for hot spots and heat
concentrations in housings subject to space constraints. The total power loss PLtot for
thermally critical applications can be determined as follows:
– Current measurement for a 24 V supply voltage
– Power loss PLtot [W] = U (24 V) * |measured value in ampères|
● Heat dissipation using open-circuit ventilation
Calculation of the volumetric flow
The power loss (thermal) dissipated by the components in an operator unit is to be dissipated
using open-circuit ventilation. The volumetric flow V required for this should be calculated at a
difference in temperature of T2 - T1 = ΔT ≥ 10K.

Risk assessment
The following standards must be used to perform the risk assessment:
● EN ISO 12100-1:2003 and EN ISO 12100-2:2003, General Design Guidelines for Machines
● EN ISO 14121-1:2007, Risk Assessment for Machinery
● EN ISO 13849-1:2008, Safety-related Parts of Machines
These considerations result in a category (B, 1, 2, 3, 4) and a performance level (PL a to e) in
accordance with EN ISO 13849-1:2008 that ultimately dictate how the safety-related parts of
the system to be monitored must be constructed.
The connection examples with different monitoring units in "Handheld units", Section: "HT 2",
Section: "Connections" → "Connection examples for acknowledgment button and Emergency
Stop button" can also be used for other operator panels and demonstrate how Category 3, PL
d according to EN ISO 13849-1:2008 can be attained with the safety-related parts of the
operator panels. Note that the overall concept of the installation must be designed with this in
mind.
1.2.4 Recycling and disposal
Products should be disposed of corresponding to the relevant national regulations.
The products described in this manual can be mostly recycled due to the fact that they contain
very few damaging substances. To recycle and dispose of your old device in an

Interfaces for direct keys
X11 on the operator panel (OP) fronts can be used to fetch the state of the direct keys. The
connection of a 20-pin ribbon cable allows the direct keys to evaluate the following components:
● Direct key module (DTM)
● X70 in the machine control panels (MCP, MPP) and the handwheel connection module
(HAM)
● X205 on the Thin Client Unit (TCU)
The signals are then forwarded to the control over the various communications networks. Note
that DTM and HAM can be operated only with PROFIBUS DP.

● NCU 7x0.3 PN with NCU-Basesoftware (Linux-based)
● PCU 50.5 with PCU-Basesoftware (Windows XP, Windows 7)
Introduction
This manual describes the structure and commissioning of the system network with
SINUMERIK solution line control and operator components with Ethernet-based
communication. The fundamentals of the system network are described first, details and
special cases are described in subsequent chapters.
Fundamentals
The system network for SINUMERIK solution line is structured as a star topology with a central
Ethernet switch, to which all Ethernet-based components of the system are connected.
For an NCU the connection is executed via the X120 Ethernet socket, for PCU it is executed via
the "Ethernet 2" connection. There is no default for all other components with two Ethernet
connections. These components have an internal 2-port switch and may be used to connect an
additional operator component. Thus in this case there can be deviation from the strict star
topology.

1.4 Networking
Handheld Terminal HT 8
38 Manual, 01/2019, A5E36371621B AD
System network
In the system network the IP address 192.168.214.xxx with subnet mask 255.255.255.0 is pre-
selected. Here there is precisely one DHCP server with DNS that can run on one NCU or one
PCU. The server ensures assignment of IP addresses to the Ethernet components in the
system network (DHCP clients) from a specified address band.
The following rules apply for assignment of IP addresses in the system network:
● For all NCUs and PCUs the commissioning engineer assigns fixed IP addresses in the
associated address bands, as well as appropriate computer names (host names). All other
(operator) components are automatically assigned an IP address from the DHCP server. Its
name is generated automatically (for MCP, MPP, HT 8), or is entered at commissioning
(TCU).
● If there are multiple NCU and/or PCU in the system network the system automatically
(depending on the start-up sequence) specifies the DHCP server and automatically ensures
synchronization of all necessary data so that the next time the system boots any other NCU
or PCU could take on the role of DHCP server. However it is a good idea to specify a DHCP
master. This is an NCU or PCU in the system network that is available at each system boot
and which regularly takes over the task of the DHCP server and DNS server.
Synchronization of data takes place in any event so that any other NCU or PCU can take
over this task. All non-master NCU / PCU wait in the system boot an adjustable length of
time for availability of the master.
Note
In a system network, on a boot server respectively - i.e. the NCU or PCU which
accommodates the active DHCP server - a maximum of 30 operator stations may be
operated simultaneously with a TCU.
A maximum of 10 operator stations with a TCU may connect up simultaneously with the
same HMI application when powering up.
Connection to a company network
Each NCU can be connected via X130, and each PCU can be connected via "Ethernet 1" to the
company network. The company network is used to exchange operating software with servers
or to execute part-programs directly from servers in the company network. Company network
and system network should always be logically and also physically separated.
Service interface X127
The service interface X127 of the NCU is used for direct connection of a PG/PC for service
purposes. Here access with STEP 7 to the PLC, and with NCU 7x0.3 PN also to PROFINET is
possible.
With direct connection (peer-to-peer) of a PG/PC to X127 it is absolutely necessary that the PG
is operated as a DHCP client.

1.4.1.2 System boot with system network
System behavior at boot
As of NCU system software V2.4 SP1 and PCU-Basesoftware V8.1, system boot behavior is
based on the following principle:
● For configuration of an NCU 7x0 with a PU 50, the default for a network configuration is as
follows: The NCU keeps the default IP address 192.168.214.1 on X120, the PCU 50 keeps
the default IP address 192.168.214.241 on Eth2.
● For a configuration of more than 1 NCU 7x0 without PCU, with one or several PCU 50, then
a differentiation must be made between two cases:
– At boot automatically all address conflicts and DHCP conflicts are resolved and the
system is ready for operation. In this configuration there is no guarantee that all NCUs
and PCUs will always receive the same IP address at each system boot.
– If in the user's view there is a requirement that all NCUs, and possibly also the PCUs, get
a defined constant IP address at each boot, for example because the IP address is
entered in the respective PLC program, then the user must configure a fixed IP address
for each NCU 7x0/PCU 50 in question, in the basesys.ini file.
● The user can specify a DHCP master in the basesys.ini file.
● Assigning names:
– The user should assign meaningful names for all NCUs in the basesys.ini file; if not the
names will be generated automatically.
– A PCU 50 always has a computer name that can be changed as needed.
● The IP addresses of TCUs and MCPs are freely assigned within the specified address band
at each boot. The MCPs are identified in the PLC via their DIP switch setting.
Using DNS name service
Availability of the DNS (Domain Name System) name service offers the following advantages
for system network administration:
● The name service enables easier configuration with names instead of IP addresses for
management of operating units: All components in the system network can be addressed
via a symbolic computer name. This name can to some extent be freely assigned, to some
extent it is derived automatically from a DIP switch setting (MCP, MPP, EKS, HT 8, HT 2).
● A computer node in the system network (NCU, PCU, TCU, MCP, HT 8, etc.) can be
addressed solely through assignment of the IP address, either via a freely selectable name
or via an internally generated name in the system network, and thus becomes independent
from its network address in the system network. Thus a change in the network address does
not necessarily necessitate a series of additional setting changes.
● In addition, the name service is used by the system for address resolution for MCP/MPP,
direct keys, and EKS when changing the user authorization.

1.4.1.3 Thin Client Unit (TCU)
TCU overview
The Thin Client Unit (TCU) for the distributed configuration permits spatial separation of the
SINUMERIK operator panel front (OP/TP) and the SINUMERIK PCU or NCU. On the
SINUMERIK solution line, the TCU is used to display the user interface of the PCU 50 or the
NCU.
It is possible to connect one TCU to several PCUs/NCUs. All TCUs and PCUs/NCUs that are
connected to one another via a switch form the "system network". The user interface of a PCU/
NCU is copied to several OPs with one TCU each. In other words, all of the TCUs display the
same screen. Operator actions can only be performed on one TCU at a time. This TCU then has
user authorization. The PCU can also have its own OP connected directly to it.
The following diagram shows a configuration example for a distributed topology:
6ZLWFK6,180(5,.'VO3&87&8+77&87&80&3
The mobile SINUMERIK HT 8 handheld terminal works on the thin client principle and
combines the functions of an operator panel with a machine control panel.
The configuration and cabling of the whole plant system based on a permissible configuration
is described in the chapter 'Network configurations".
Supplementary conditions
For operation of a TCU:
● In the system network, the number of active TCUs is limited:
– a maximum of 2 TCUs: NCU 710.3 PN
– a maximum of 4 TCUs: NCU 720.3 PN or NCU 730.3 PN
– a maximum of 4 TCUs: PCU
Any number of TCUs can be operated in the system network.
● CompactFlash Cards cannot be used on the TCU.
● A 16 bit or 32 bit depth of color setting may be selected.
● If a PC keyboard is connected to the TCU, it is not possible to ensure that all special keys,
e.g., multi-media keys, will be transferred to the software of the NCU / PCU.

Preconfiguration of the TCU
The TCU is configured as a DHCP client and primarily accepts IP addresses from SINUMERIK
components, from the DHCP server of such components that are inherent to SINUMERIK, for
example, an NCU at X120 or a PCU on the system network or from a default DHCP server. The
behavior of the TCU cannot be modified here.
7&8
A TCU is a SINUMERIK DHCP client.
The TCU has a single Ethernet connection.
A TCU executes a boot via the network. The boot server is the computer node from which the
TCU also obtains its IP address.
Pre-configuration of the PCU
A PCU has two Ethernet interfaces with default settings suitable for use with SINUMERIK
solution line:
3&8
(WK(WK
Eth 1 is pre-selected as a default DHCP client for connection to a
company network.
Eth 2 is pre-selected as a SINUMERIK DHCP server for connection
to a system network. On Eth 2 the fixed IP address
192.168.214.241 is pre-selected.
Preconfiguration of the NCU
On the X120, the NCU is preconfigured for the SINUMERIK DHCP protocol. The NCU is pre-
selected here as a SINUMERIK DHCP server. On X120, the NCU occupies the fixed IP address
192.168.214.1 with the subnet mask 255.255.255.0 in its capacity as a DHCP server. The
DHCP server of the NCU assigns IP addresses from the range 192.168.214.10 –
192.168.214.239 to the DHCP clients. The behavior of the NCU on X120 cannot be modified.

Restricting the available address band that is managed by the DHCP server of the NCU frees
up IP addresses 192.168.214.2 to 192.168.214.9 as well as addresses 192.168.214.241 to
192.168.214.254 for network nodes with fixed IP addresses.
1&8
;;;
The NCU has three Ethernet connections:
- X120 to connect to the system network with an active DHCP serv‐
er (Eth 0)
- X130 to connect to the company network as a default DHCP client
(Eth 1)
- X127 as a service connection with an active DHCP server (Ibn 0)
On X130, the NCU is set as a default DHCP client for the address reference from a company
network. The IP address received here is specified by the DHCP server from the company
network.
On X127, an NCU is a standard DHCP server (in contrast to the SINUMERIK DHCP server).
On X127, the NCU has the fixed IP address 192.168.215.1 with the subnet mask
255.255.255.224). The IP addresses 192.168.215.2 – 192.168.215.23 are dynamically
assigned to the DHCP clients. The range 192.168.215.24 - 192.168.215.30 is reserved, and
can be used by stations on the network with a fixed IP address, e.g. by a modem.

The central area is for setting the TCU parameters:
● "HT 8 individual mode" (yes/no)
This is only visible with HT 8, and is used to switch between Auto Mode and Individual Mode.
There is no need to make any settings if an HT 8 is in Auto Mode, as the name is determined
automatically: ("DIP<n>") the MCP address and TCU index are determined by the DIP
setting ("DIP<n>").
It is possible, however, that another device is registered for the name selected. Such
situations may only prove to be temporary, as is the case when DIP settings or two HT 8
have been confused. For this reason, this status is not reported as an error immediately, but
identified as a possible problem instead ("potential name/DIP setting collision"). The text will
only read ("Name/DIP settings collision") if the situation remains unchanged after some time
has elapsed.
The process itself is unaffected, as the changes only relate to how the warning or error is
displayed. The explanatory text informs the user that they have probably assigned the same
DIP number twice and suggests they change one of them before rebooting the HT 8.
● "Operator panel index - TCU" (0-255)"
This specifies the TCU index. It matches the [Station] tcuIndex setting from the config.ini file.
● "Machine control panel address - MCP" (0-255)

If, as described above, the system automatically follows the "New" path, an additional message
will appear: "This operator panel (TCU) must be new, because there are no inactive panels."
This message will not appear if "New" is selected manually.
Figure 1-20 TCU menu: Name of TCU
An available TCU name is suggested in the input field, although the user is able to change this.
The default name is "TCU<N>", where <N> is the lowest number yet to be used. If, however,
the name is already allocated after the OK softkey has been pressed (which may happen if a
number of TCUs log on at the same time) and the suggestion has not changed, a new and
unused name will be specified.
If the name selected was still available, this will now be allocated, and the TCU settings can still
be adapted if required. To enable any changes to be made, a new dialog will appear in which
all the parameters have been pre-assigned their default values. You can make any changes
you like or just select "OK" to accept the existing values.

Procedure:
1. Connect HT 8 to a connection module and calibrate the touch screen.
Additional softkeys are available for convenient touch panel operation:
– "OK" has the same effect as the <INPUT> key
– Select "DEF" to save the "Default" settings.
– "Edit" has the same effect as the <F10> or <MENU SELECT> key.
2. Select HT 8 Individual Mode:
According to the default setting for an HT 8, "HT 8 Individual Mode" is deselected with "No".
This means "Auto" mode is activated for automatic detection in the system network. The HT
8 is automatically detected based on its name "DIP_". If "HT 8 Individual Mode" is activated
with "Yes", the HT 8 is identified by its MAC address on the system network.
3. For an HT 8, confirm the "DIP..." name proposed by the system or adapt the name. You can
select any other characters.
Press the <INPUT> key to apply the following values as default settings for the HT 8:

Definition: Operator panel
The term operator panel designates a unit that consists of an OP/TP, a TCU or PCU and a
machine control panel (MCP), that are connected to each other via Ethernet.
All TCUs and PCU 50 can be used along with OP/TP with "integrated TCU", e.g.: OP 08T,
OP 015T, TP 015AT.

Specifying settings without machine control panel
If a PCU or a TCU has no Machine Control Panel (MCP), you must set one of the two following
options:
● MCP address = 0 or no entry
After the change of user authorization, there is no switchover of the machine control panel;
the previously active MCP remains active.
● MCP address = 255
If the user authorization is transferred to this PCU or TCU, the previous machine control
panel is deactivated and there is no active machine control panel from this point on.
Connecting a replacement TCU
Procedure:
1. Connect the new TCU.
The following dialog lists the TCUs on the system network along with their "active" or
"inactive" status.

2. Select the name previously assigned to the faulty TCU from the "New operator panel (TCU)"
dialog. As a result, the new TCU is recognized on the network and acquires all of the
configuration settings from the TCU that has been replaced.

Prerequisite
Note
The "Operation without SINUMERIK OP" option is required when using more than 1 external
VNC Viewer.
Operator control without SINUMERIK OP
If the "Operation without SINUMERIK OP" option is set, then a list of viewers that can be
assigned in tcu.ini is handled by the system just like internal viewers (=TCU); this means that
these viewers have full user authorization and participate in the user rights management.
Towards the outside, they behave just the same as the viewer on the SINUMERIK operator
panels.
Restrictions
Restrictions for such external operator control units are:
● Neither MCP and direct keys nor an EKS system can be assigned. This also means that
these devices cannot be activated to be an operator control unit in the system.
● Direct control keys cannot be triggered, i.e. the softkeys to the direct keys can be triggered
in the operating software. However, the keys do not appear in the direct key image to the
PLC.
● There is no configuration file config.ini, as for a TCU, i.e. the settings to be made to a TCU
are not possible for such an operator control unit (power-up behavior, displacement, t:m:n);
however, the displacement mechanism to the external operator control units is effective.
● An external operator control unit is never signaled as active operator station in the PLC.

1.4.2.9 Displacement mechanism for TCUs
Supplementary conditions
The following supplementary conditions apply when operating the TCU:
2 active TCU connected in parallel to NCU 710.3 PN
General information and networking
1.4 Networking
Handheld Terminal HT 8
Manual, 01/2019, A5E36371621B AD 73
4 active TCU connected in parallel to NCU 720.3 PN, NCU 730.3 PN
4 active TCU connected in parallel to PCU
To operate a machine with more operating stations then the maximum number the
displacement mechanism ensures that only the permitted number of TCUs are active in
shadowing grouping. The remaining TCUs are switched to a passive mode, which means they
no longer represent a load relative to the resources. Thus the number of TCUs that can be
connected to one HMI application is practically no longer limited, the limitation is the number of
concurrently active TCUs.
Configuration
There are two new entries in the config.ini file for a TCU for the displacement mechanism:
●SUSPENDLOCK: controls whether the TCU can be displaced via the displacement
mechanism.
SUSPENDLOCK = 0 means that a displacement disable is not set (preset), i.e. the TCU may
be displaced by any other TCU.
SUSPENDLOCK=1 means that this TCU can never be displaced.
●SUSPENDPRIORITY: This entry specifies a priority for the displacement mechanism to the
TCU. In a displacement process the TCUs among the active TCUs with the lowest priority
that do not have a displacement disable will displaced. The priority is specified as numeric
value in the range 1 - 10.
The preset is 1 (lowest priority).
Note
If you set a displacement disable for a TCU then specification of a displacement priority is
unnecessary because it never is used due to the displacement disable.
Displacement rules
The TCU can assume the following states:
●The TCU is active and has user authorization: This can be identified as the TCU shows the
screen of the operating software and the screen is bright.
●The TCU is active, however, in the monitoring mode (i.e. it presently has no user
authorization): This can be identified as the TCU shows the screen of the operating
software, however, it is darkened in comparison to the TCU with user authorization.
●The TCU is passive: The TCU shows the selection menu of the possible connections
instead of a screen of the operating software, and the softkey for selection of the last active
connection of the TCU is shown in color.
When a TCU boots, the TCU always attempts to establish the first connection specified in its
config file. The TCUs from a shadowing group establish their specified connection one after the
other as long as the maximum number of permissible active operator units is not exceeded.
If a TCU encounters the situation that this number is already reached in its power up, then it
attempts to obtain a connection via the displacement mechanism. If it can displace a formerly

active operator unit then it takes on the active status itself, otherwise it transitions to passive
status immediately after booting.
1.4.2.10 Disable switchover between TCU via PLC
Overview
The TCU switchover disable offers the option of dynamically disabling switchover from one
TCU to the next when the system is running via the PLC. For the duration of the disable, a user
authorization request to change user authorizations between TCUs will be ignored by the
system and rejected.
The rejected user authorization request causes a message to be output in the dialog line of the
HMI, in the form of a feedback message for the requester. The message disappears after five
seconds.
HMI ↔ PLC data interface
The “switchover disable” function is always active and does not have to be switched on
explicitly. The function is controlled by a data bit in the PLC. The HMI transfers the active OP
to the PLC, thus forming the basis of the control function in the PLC.
The control bits and control information for this function are stored in the m:n data interface of
the PLC. In terms of m:n, this function can be operated separately for the currently overridden
HMIs in both m:n online interfaces (DB19.DBW120 ff for HMI1 and DB19.DBW130 ff for HMI2).
If a system is not running an m:n, only the first m:n online interface is used for this function.
Switchover disable is controlled by a TCU_SHIFT_LOCK bit, managed by the user, on each
HMI in the PLC. The bit address for the first HMI is DB19.DBB126.6 and DB19.DBB136.6 for
the second HMI.
The PLC m:n online interface is expanded so that byte DB19.DBB118 is still added to the first
interface and byte DB19.DBB119 to the second. These bytes acquire the index of the active
TCU (of the active OP) for the appropriate HMI. The byte is called TCU_INDEX. The
appropriate HMI uses the TCU index configured for the active TCU to describe the TCU_INDEX
byte.
The TCU_SHIFT_LOCK bit is monitored by the appropriate HMI. A value = 1 triggers the
switchover disable; switchover is enabled if the value returns to 0. The TCU_SHIFT_LOCK bit
can be set, for example, to the PLC by the user pressing a key or it can be managed by the PLC
user program according to its own logic. The TCU_SHIFT_LOCK bit is managed in the PLC
exclusively by the user; the HMI only accesses this bit in read-only mode.
The HMI assigns the configured index of the TCU or PCU whose OP currently possesses user
authorization in the shadow grouping. If no OP is active, a value of 0 is entered in TCU_INDEX.
If no TCU index is configured for the active TCU (active OP), the value 255 = undefined is
presented as the TCU index. This means that the values 0 and 255 may not be configured as
the TCU index.

carried out independently of the mode set on the HMI for allocation of user authorizations (veto
mode), i.e., a change of user authorization is rejected.
This message appears on all OPs for approximately 5 seconds:
"No switchover: Switchover disable set in current PLC."
While this message is displayed, operations on the OP with the user authorization can still be
carried out unaffected.
Note
The switchover disable only relates to changing the user authorization on the OPs in a
shadowing grouping on a PCU.
Active switching from one OP to another PCU is not prevented.
Special features
The following special cases should be noted:
● Even if switchover disable is set, the TCU_INDEX field value may change in the PLC. This
is the case if:
– The OP in possession of the user authorization is actively switched to another PCU.
Depending on whether another TCU takes on the user authorization or whether no TCU
is currently active, either the index of the TCU or the PCU itself (if its directly connected
OP becomes active) is entered, in exactly the same way as when there is a user
authorization switchover.
This can also be the value 255, if no TCU index is available for the OP. 0 is entered if an
OP is no longer available in the shadow grouping.
– An m:n switchover is in progress. The HMI program of the incoming PCU deactivates the
HMI program which is active on it. An OP from the shadow grouping of the new
(incoming) PCU must receive the user authorization. The TCU index of this OP is
entered in the TCU_INDEX field.
– A PCU is disconnected from a NCK/PLC in the context of m:n. No HMI program and,
therefore, no OP with user authorization is then available on the exited NCK/PLC. This
is signaled independently of a switchover disable by entering the value 0 into the
TCU_INDEX field.
● If a TCU is actively switched over to another PCU, it can be deactivated there, i.e. it does not
obtain the user authorization, if a switchover disable is set for the destination PCU.

● With an m:n PCU switchover – the PCU is switched to another NCK and, therefore, to
another PLC – the PCU takes on the switchover disable settings of that PLC.
● The m:n interlock options on the PLC side have priority over the TCU switchover disable, so
that a set TCU switchover disable cannot prevent an m:n switchover. If necessary, the m:n
interference options should be synchronized here with those for the TCU in the PLC. It may,
for example, be practical to set or remove the m:n displacement disable simultaneously with
the TCU switchover disable.
Obtaining user authorization
On a TCU that has no user authorization, the first key that is pressed serves exclusively to
request the user authorization, i.e. this key is not evaluated by the operating software.
The settings for the right to veto are stored in file tcu.ini and are only effective if the operating
software is installed on the PCU. At the OP of the TCU, the operating software can be operated
in exactly the same way as an OP directly connected to the PCU.
Note
These operator input sequence steps must only be carried out by qualified personnel!

1.4.3 Network configuration
1.4.3.1 Permissible network topologies
Ethernet connection
A SINUMERIK 840 D sl can only be operated as a network within which the individual
components communicate with one another via Ethernet connections. This network must be
set up.
The individual components are factory-set so that the most frequently occurring standard
configurations can be operated without changing the settings related to the network.
Division into system network and company network
On the SINUMERIK solution line, the components are generally split into a company network
on the one hand and a system network on the other.
The connection to the company network provides access to the network drives, for example.
On the system network, process data communication and image transmission runs from the
components with operator software to the display units – the respective TCU.
This split is performed physically by means of the prescribed use of the Ethernet interfaces on
the components:
● A TCU is connected exclusively to the system network.
● An NCU is always connected to the system network via X120.
● Ethernet interface Eth 2 of the PCU is preconfigured for connection to the system network;
while Ethernet interface Eth 1 is used for connection to the company network.
● An NCU is connected to the company network via X130.
Meaning of the connections:
○ Eth 1 as a DHCP client
● Eth 2 as a DHCP server
■ Eth 2 with a fixed IP address

Configuration 3: NCU and TCU
Description
6ZLWFK1&87&86\VWHPQHWZRUN&RPSDQ\QHWZRUN;;
The TCU is connected to the NCU (directly) using a crossed Ethernet cable. On X130, the NCU
is connected to a switch to the company network with a straight cable.
As in configuration 1, there is a direct Ethernet connection between a TCU and X120 of the
NCU. NCU and TCU are suitably preconfigured with IP addresses. The IP addresses used here
are not significant for further operation.
IP configuration: DHCP server on the company network
On X130, the NCU is set to the address reference via DHCP. If the company network has a
DHCP server that provides the NCU with an IP address (IP configuration), the NCU is
integrated into the company network.
Depending on the infrastructure available or the level of network administration of the company
network, the following network parameters must be set for the NCU on X130:
● Computer name on the company network
● Address of a DNS server
● Address of a gateway (default router)
The IP address of the NCU to this connection is also assigned via network administration.

If the company network offers a low level of administration (in the worst case scenario the
network has only one DHCP server that assigns the addresses from a predefined address
range) the NCU receives an IP address that is initially unknown.

The NCU and PCU are connected via a crossed Ethernet cable.
On X120, the NCU occupies the fixed IP address 192.168.214.1 in its capacity as a DHCP
server (not used in this configuration). For this Eth 2 configuration, the PCU is assigned a fixed
IP address in the range 192.168.214.241 – 192.168.214.249 with a subnet mask
255.255.255.0 .

In this configuration, a switch is also required for the system network. All components are
connected using straight Ethernet cables.
In terms of address allocation and the settings that need to be made, this configuration is
identical to that of configuration 4. However, in this case, the DHCP server of the NCU actually
supplies the TCU with an IP address and serves as a boot server for the TCU.
The observations made for configuration 3 also apply here in relation to the connection to the
company network. The connection to a switch on the company network is made via a straight
Ethernet cable.
To connect one TCU to both HMI systems you must create an additional connection to the NCU
for the TCU, as described in the following chapter:

For service purposes a programming device is connected to the NCU at X127 as a standard
DHCP client (automatically obtain an IP address). An NCU is a standard DHCP server on X127.
On X127, the NCU occupies the fixed IP address 192.168.215.1 with the subnet mask
255.255.255.224.
At X127, IP addresses from 192.168.215.2 onwards are assigned via DHCP; e.g. to connect a
programming device. This is the reason that a fixed IP address must not be set at the
programming device.
1.4.3.4 Example: Configuring a VNC connection to a PC
Requirements
In order to use a TCU to get visual access to a computer from a SINUMERIK system via VNC,
the following requirements apply:
● The boot server (active DHCP server) in the system network must be an NCU.
● This NCU must be integrated via X130 or X120 into the network to which the computer to be
monitored is connected.
General information and networking
1.4 Networking
Handheld Terminal HT 8
84 Manual, 01/2019, A5E36371621B AD
● The computer to be monitored must be configured in the config.ini configuration file of the
TCU according to the general configuration for a TCU in a separate host section as a
switchover target for this TCU.
Where necessary, a password has to be specified in the configuration, if the VNC server
requires one on the target system (see below).
● To ensure that the TCU recognizes the new switchover target, the TCU requires a restart
and reboot.
● The screen resolution of the computer to be monitored must be adjusted to the conditions
of the TCU, since otherwise the TCU scales the image received to its possible range of
representation, which would adversely affect the representation on the TCU.
Configuration

If an emergency stop is triggered, the button locks into place.
If the button is locked into place, it can be unlocked by rotating it to the right.
Emergency Stop button
Press the red button in emergencies when
∎ people are at risk,
∎ there is the danger of machines or the workpiece being
damaged.
As a rule, when operating the Emergency Stop button, all
drives are brought to a standstill with max. braking torque.

For other responses to the Emergency Stop:
Refer to the machine tool manufacturer's instructions!
The signals are sent via the connecting cable to the terminal box or the connection module and
are available for further wiring.
Rotary override switch
The rotary override switch of the HT 8 has 19 positions.
The evaluation scale (0 to max.) is specified by the machine's manufacture in the form of
machine data.
Enabling button
The HT 8 has two enabling buttons that are logically grouped.
This allows the enabling function to be triggered by either the left or the right hand during normal
operation.
The enabling buttons are configured as 2-channel, 3-position switches for the following button
positions:
● Released (no activation)
● Enabling (center position) - enabling for channel 1 and 2 is on the same switch.
● Panic (completely pushed through)
Note
Monitoring the enabling function
● The enabling duration is monitored to avoid that the enabling button is permanently
bypassed. The enabling outputs are opened after max. 30 min permanent enabling. The
enabling outputs are only closed again after first releasing the enabling button and then
actuating it again. The enabling time of 30 min can be extended by switching to the second
enabling button before the 30 min expires.
● The system checks the synchronism of the two enabling button circuits of the mechanical
enabling button. The two enabling button circuits (of the button) must be closed within 2
seconds. As a consequence, it is not possible to actuate just one enabling circuit and
therefore provoke a fault.

8 MCP process image.
NOTICE
Lack of care for traversing can cause damage to the tool/workpiece
The increments per revolution for a handwheel on a mobile HT 8 amount to 50 increments/
revolution; for a stationary unit, it is 100 increments/revolution. A different length of the
traverse path results from this difference.
3.3 Screen brightness control
If a screen with high contrast is displayed unchanged for longer than 1 hour, the screen
brightness control must be activated (screen switched dark) in order to protect the TFT display
against a phenomenon known as "burn-in" of the last displayed screen.
For more information see:

The PN terminal box is available in two versions.
● PN Basic terminal box
The PN Basic terminal box can be used if no hot-plug capability is required. The Emergency
Stop circuit can be overridden here by external mechanisms.
● PN Plus terminal box
The PN Plus terminal box features hot-plug capability. This means that it is possible to
connect and disconnect during operation without any disruption.
The emergency stop circuit is automatically maintained during the switching of connectors.
Note
The exterior of the PN terminal box versions only differs in terms of what is printed on the side.
The terminal boxes feature two rotary coding switches (S1 and S2) so that a unique ID can be
set for the purpose of station identification. See Chapter interfaces (Page 109).

5.4 Connecting cable
The connecting cable is an industrial cable, can tolerate bending in-line with what is required in
practice – and is resistant to many solvents and lubricants.
The connecting cable is available in various lengths. You will find detailed information in
Section: "Accessories".
①Metallic push-pull round connector (ODU connector)
②RJ45 plug to connect to the Ethernet
③Plug connector for enabling button, Emergency Stop, 24 V and safety signals
④Strain relief device and kink protection
Figure 5-9 Connecting cable for the HT 8
The connecting cable is connected to the HT 8 using the RJ45 plug connector ② and plug
connector ③. ODU plug connector ① is used to connect the connecting cable with the terminal
box/connecting module MPP. The tightening torque for the nut of the ODU socket is 6.5 Nm.
The HT 8 has two cable entries at the rear for connecting the cable. This makes it possible to
attach the connecting cable at either the right or left side.
One of the cable entries is closed at the factory by a connector in which a USB connection is
integrated (with IP65 cover).
Routing the connecting cable
1. Open the cover by unscrewing the six PT
screws (4 x 20 mm) approximately 1 cm.
To do this, use a Phillips size 2 screwdriver.
Connecting
5.4 Connecting cable
Handheld Terminal HT 8
Manual, 01/2019, A5E36371621B AD 115
2. Insert the connecting cable in the appropriate
entry (left or right).
Press the cable downward slightly until it rests
completely on the fastening lugs
Insert a plug in the cable entry that you do not
intend to use.
3. Press the plug connector firmly into the power
supply socket.
4. Connect the RJ-45 connector to the Ethernet
socket.
WARNING
Improper installation of the cable can result in failure of the safety functions.
Please observe the following before you reattach the cover:
● Check to ensure that all of the conductors are aligned and straight and check the firm
seating of the plug connector.
● Make sure that the connecting cable sleeve is installed correctly.

5.Attach the cover by tightening the six PT
screws.
NOTICE
Damage to the housing
The housing of the HT 8 is made of plastic. Therefore, the mounting hole threads cannot
handle the same amount of stress as a comparable metallic housing. Therefore, do not
exceed 0.4 to 0.5 Nm of torque when tightening the screws (also for protecting the connecting
cable).
If you use a power screwdriver, ensure the max. speed of 600 rpm is adhered to (torque: 1
Nm).
The screws of the cover may only be loosened or tightened a maximum of 20 times.
Otherwise, there is the danger that the threads might become damaged and the seal of the
housing will be compromised which could lead to failure of the device.
5.5 Power Supply
The HT 8 is supplied with power via the terminal box/connection module.
The input voltage range is designed for +24 VDC.
For further details, see: "General notes and interconnection" → "Operational planning"→
"General electrical conditions" → "Power supply".

5.6 Unplugging/plugging during operation
The ability to detect a connected HT 8 in the PLC
1. HW solution:
Interface X7 of the Basic PN connection module signals "HT 8 Present" at pin 1 for the
"active" connection module (see interfaces (Page 109)).
If the connection module is "inactive", this signal is not set.
This makes the "active" connection module detectable in the PLC by wiring the above-
mentioned pins of all connection modules to digital I/Os on PLC I/O modules.
2. Permanently configured MCPs / HT 8 connected to one control:
If there are only permanently configured MCPs / HT 8 that a control, removal of the MCP or
HT 8 triggers the PLC alarm "400260 Machine Control Panel failed".
Based on this, an "active" or "inactive" MCP / HT 8 in the PLC can be detected.
The failure of an MCP / HT 8 is, however, only detected in the PLC if max. 2 MCP / HT 8 are
permanently configured and no MCP switchover using FB9 (e.g. triggered when operator
focus is switched at the operator panel).
Note
Removing an HT 8 where the integrated machine control panel is active
Depending at which interface in the PLC (FB1: MCP1 or MCP2) the HT 8 is configured, before
removing the HT 8, the transfer of the machine control panel signals must be stopped.
This is possible as direct axis via data block DB7 (instance of the FB1).
To do this, set the corresponding interface signal to "true":
● 1. Interface: DB7.DBX62.1 (MCP1Stop)
● 2. Interface: DB7.DBX62.2 (MCP2Stop)
If the machine control panel signals are not stopped, then the message "400260 machine
control panel x failed" is displayed at the user interface:
Transfer of the machine control panel signals can be restarted after inserting the HT 8. To do
this, set e.g. the PLC interface signal DB7.DBX62.1 (MCP1Stop) to "false".

6.1.3 Configuring user-specific key labeling
Labeling the keys for the HT 8
The texts of the CPF menu (CPF: Control Panel Function) for the HT 8 can be labeled with your
own texts in the particular language of the country.
The texts are created in the "slck_xxx.ts" file.
"xxx" = language code for the corresponding language-specific labeling.
You can create and edit this file using the HMI or also externally on a PC.
Note
If you wish to create or edit the file on a PC, use an editor that supports UTF-8 coding.

Procedure
1. You can copy the sample file " oem_slck_deu.ts" from the following directory: /siemens/
sinumerik/hmi/template/lng.
2. Store or create the file in the /oem/sinumerik/hmi/lng or
/user/sinumerik/hmi/lng directory.
3. Give the file a name, e.g. for German texts: "slck_deu.ts".
If you wish to create the key labeling for additional languages, then a separate file must be
created for each language. Save the file with the appropriate language code in the file name.
To do this, use the language codes specified above.
4. Open the file and in the <message> and </message> area, define the key labeling.
5. Restart the HMI.
In order that the key labeling is displayed during the program runtime, the file must be
converted into a binary format. This conversion is only executed when the HMI powers up.

Display/skip the labeling of traversing keys on HT 8
In order to inscribe the traversing keys, the names of the first six axes are established from the
machine data 10000: AXCONF_MACHAX_NAME_TAB (indexed using DB 10, bytes 8 to 13).
The LED image of HT 8 serves as the interface for displaying the labeling by the PLC. The PLC
sets a bit in the LED image of the HT 8 to display or skip the traversing keys:
Signal AB n+6 bit 7 = 1 for displaying
Signal AB n+6 bit 7 = 0 for skipping
Note
To ensure that the labeling of the traversing keys is displayed correctly, the names of the axes
must not exceed 10 characters.
Example with labeling of traversing axes displayed:
Figure 6-1 Traversing axes displayed
Acknowledging display/skipping by HMI on PLC
The HMI communicates to the PLC whether the traversing keys are displayed or hidden. This
is done using bit 7 in byte 72 of DB 10:
Displayed: DB10.DBX72.7 = 1
Skipped: DB10.DBX72.7 = 0

6.2.2 Configuring user-specific key labeling
Labeling the keys for the HT 8
The texts of the CPF menu (CPF: Control Panel Function) for the HT 8 and the traversing keys
can be labeled by the user with his own texts in his specific language.
A language-dependent file ht8_xx.ini is provided in directory \mmc2\language for this purpose.
Only edit a copy of this original file and place this copy in one of the following directories:
● user\language
● oem\language
● addon\language
There are two sections in file ht8_xx.ini; one for the CPF menu ( [CPFSoftkeyText] ) and one for
a maximum of 31 traversing keys ( [AxiskeyText] ). With no entry (e.g. U2="") or for the value
<empty> (e.g. U2=<empty>) no labeling text is displayed on a softkey or on a traversing key (-/
+).
● The entries for the CPF keys are pre-assigned as standard with U1 ... U16.
● The texts for the traversing keys are not activated as default setting for the following reason:
If no traversing key text is read, the name is determined from the machine data – with the
axis number as index – and correspondingly output: ("/ACC/NC_TEA/
$MN_AXCONF_MACHAX_NAME_TAB[" & chAxisNbr(k%) & "]", chAxisName(k%)
Note
It is not possible to combine the labeling texts – e.g. a part of the name from the INI file and
another part from the machine data.
