1.2.1.2 Grounding concept
Components
The SINUMERIK 840D sl system consists of a number of individual components which have
been designed so that the system complies with the appropriate EMC and safety standards.
The individual system components are:
● Numerical Control Unit (NCU)
● Machine Control Panel (MCP), Machine Pushbutton Panel (MPP)
● Keyboard
● Operator panels (operator panel front + TCU/PCU)
● Distributor box and handheld unit
● S7-300 I/O with IM 153 interface module
Grounding measures
The individual modules are attached to a metal cabinet panel. Insulating paints on the mounting
points (e.g. tension jacks) must be removed.
It is permissible to cluster the operator control components regarding connection/potential
bonding.
Example: The control panel on the swivel arm.
It is sufficient in this instance to connect the ground connections of, for example, the PCU,
TCU, and operator panel front using a cable and to route a shared grounding conductor to the
central ground connection in the control cabinet.

Rules for routing cables
In order to achieve the greatest possible EMC compatibility for the complete system (control,
power unit, machine), the following EMC measures must be carefully observed:
● If necessary, signal and power cables may cross one another (if possible at an angle of
90°), but must never be laid close or parallel to one another.
General information and networking
1.2 Application planning
● Only use cables approved by SIEMENS for the signal lines from and to the Control Unit.
● Signal cables must not be routed close to strong external magnetic fields (e.g. motors and
transformers).
● If signal lines cannot be routed a sufficient distance away from other cables, they must be
installed in grounded cable ducts (metal).
● The operator panel fronts, MCPs, MPPs, and full keyboards must be installed in metallically
enclosed EMC-compatible housings.
Note
For further information on interference suppression measures and the connection of
shielded cables, please refer to the EMC Installation Guide.

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

Figure 1-1 Means of heat dissipation
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

1.2 Application planning
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 P
Ltot
for
thermally critical applications can be determined as follows:
– Current measurement for a 24 V supply voltage
– Power loss P
● 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.
[W] = U (24 V) * |measured value in ampères|
Ltot

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.

● Maximum cable length 3 m (Length including the supply cable to the hub and the connected
terminal device; only 1 hub at maximum is permitted. It should be noted that some
keyboards already have a hub.)
NOTICE
Cables that are too long can cause the screen to freeze
Observe the following restrictions for the USB front interface for connecting operator
panels to the keyboard, mouse or USB FlashDrive:
● Maximum cable length: 1.8 m
● Extension cables are not permissible
● Hot-plugging-capable devices are connected during operation and are identified
automatically.

The handwheels can either be operated with TTL or differential signals.
You set the signal type using S1 (wire bridge) on the COM board.
The handwheels are supplied with 5 V ± 5% and 100 mA via the interface.
Contour and velocity specification via handwheel are not supported.
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.

Introduction
Fundamentals
System network
General information and networking
1.4 Networking
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.
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.
In the system network the IP address 192.168.214.xxx with subnet mask 255.255.255.0 is preselected. 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.

General information and networking
1.4 Networking
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.

3&8
7&8+77&87&8
0&3
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)
General information and networking
1.4 Networking
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:
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.

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.
● Machine control panels connected via a PROFIBUS network are not supported for
switchover.
● Distributed memory media that are connected to the TCU via USB can be used.
1.4.1.4 Factory default settings
Meaning of the symbols:
○ Eth 1 as a DHCP client
● Eth 2 as a DHCP server
■ Eth 2 with a fixed IP address
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.
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.

Preconfiguration of the NCU
On the X120, the NCU is preconfigured for the SINUMERIK DHCP protocol. The NCU is preselected 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.
General information and networking
1.4 Networking
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.
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.
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.
Reserved IP addresses for NCU and PCU
The following defaults apply on delivery:
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)

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.

● "Electronic key system index - EKS" (0-255)"
This specifies the index of the associated EKS. It matches the [Station] eksIndex setting
from config.ini.
● "Enable direct keys" (yes/no)
This specifies whether direct keys (if present) should communicate with the PLC (yes) or
be treated as ordinary keys (no).
"OK" saves any modified values to the config.ini file or to the Flashstore (HT 8 individual mode).

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

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.

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.
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).
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
● The TCU is active, however, in the monitoring mode (i.e. it presently has no user
● The TCU is passive: The TCU shows the selection menu of the possible connections
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

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.

The TCU index is set in the "OP Properties" dialog of the "System Network Center" program.
If the TCU_SHIFT_LOCK bit is set for switchover disable, a user authorization request is not
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.
Special features
Active switching from one OP to another PCU is not prevented.
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.
Services:
X DHCP
X TFTP
X FTP
✔ VNC
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
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.

IP address in the range 192.168.214.241 – 192.168.214.249 with a subnet mask
255.255.255.0 .
The observations made for configuration 3 also apply here in relation to the connection to the

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

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.

● 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
Figure 1-25 Configuration example
Configuration
The config.ini file is located in the following directory:
NCU: /user/common/tcu/<TCU name>/common/tcu
PCU (Windows XP): F:\user_base\common\tcu\<TCU name>\common\tcu
PCU (Windows 7): C:\ProgramData\Siemens\MotionControl\user\common

sinumerik/hmi/appl/systemconfig/tm/ directory to the /oem/sinumerik/hmi/
cfg/ directory. After this, a system restart is necessary.
Note
Subsequent changes
Once the file has been copied, no further settings (e.g. changing language) can be
implemented on the SINUMERIK Operate. If you want or need to implement changes later,
the systemconfiguration.ini file can be renamed (e.g., as systemconfiguration.save). After
this, a system restart is necessary. Following the restart, the full functional scope of
SINUMERIK Operate is available once again.

Thanks to the tension jacks on the OP 012, drill-holes or screw holes are not needed.
This retaining method also enables the IP65 degree of protection (but only in conjunction with
a circumferential seal and when the protective USB cap is fitted).
Note
The OP 012 is supplied with what are known as "small" tension jacks. If you have the "large"
tension jacks (6FC5248-0AF06-0AA0) in stock, then you can also use these.

Installation
5.2 Assembling an OP 012 and a PCU
The PCU must now be bolted to the mounting brackets prior to assembly (if this has not already
been done). See Section in the “PCU 50.5” manual under “Assembly" → "Assembly of PCU
and operator panel front (standard mounting)"
Procedure
① Mounting slots for PCU lugs
② Slots for inserting softkey labeling strips
③ I/O USB cable K1
④ Display cable K2
⑤ Cover plate for keyboard controller connections
⑤ Retainers
Figure 5-3 Rear of the OP 012
1. Place the OP 012 face down on a flat, soft (to avoid scratches) surface.
– Installation of the direct key module (see section in the “Direct key module" manual
under "installation" → “Combination with OP 012")
– Install or replace the softkey labeling strips (see Softkey labeling (Page 102))
2. Remove the PCU's interface cover.
3. Place the PCU with the lugs of the bolted-on mounting brackets into the mounting slots on
the OP 012 as shown by the white arrows in diagram (A).
To make it easier to insert the lugs, it can be helpful to reduce the 90° angle between the
PCU and OP 012 by tilting the PCU as shown by the black arrow in the picture.
4. Insert cables K1 ① and K2 ② of the OP 012 in the connector strips of the PCU [see the
gray arrows in the diagram (A)]. Make sure that the connectors lock in audibly and that the
locks [see arrows in diagram: (B)] are closed.
5. Swivel the PCU into its final position and secure it with knurled screws, tightening torque
of 1.8 Nm [see diagram: (C)].
