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

Preparation for mounting

WARNING

Electric shock in the event of an individual error when grounding is insufficient

If the panel is installed with inadequate grounding in an environment with hazardous voltages,

this may cause an electric shock in the event of an individual error. This can result in death,

serious injury and material damage.

Adequately ground the conductive parts of the panel in accordance with the nationally

applicable regulations. When dimensioning the protective conductor connection, note the fuse

ratings of the electrical circuits with hazardous voltages, which would have an effect in

possible individual error scenarios.

WARNING

Parasitic voltage

If the device is installed with inadequate insulation in an environment with higher/more

hazardous voltages, parasitic voltages may occur. This can result in death, serious injury and

material damage.

Insulate the cables appropriately for the highest voltage coming into consideration.

The safety of a system with an integrated operator panel front is the responsibility of the system

installer.

The installation is performed in accordance with the installer's instructions.

Observe all the relevant information from this manual regarding installation.

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.

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/SIMATIC IPC or NCU.

With SINUMERIK solution line, the TCU is used to visualize the user interface of the PCU 50,

SIMATIC IPC for SINUMERIK with PCU basic software or NCU.

One TCU can be connected to multiple PCUs/IPCs/NCUs. All TCUs and PCUs/IPCs/NCUs

that are connected to one other via a Gigabit switch form the "system network". The user

interface of a PCU/IPC/NCU is copied to several OPs each with one TCU. This means that all

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 classic operator panel fronts can be used with an IPC 427E if a TCU is available.

Supplementary conditions

The following supplementary conditions apply for the operation of a TCU:

● In the system network, the number of active thin clients 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/IPC

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/IPC.

● 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.

● The TOP Panels must be networked on the basis of the Gigabit standard, e.g. Gigabit switch

or Ethernet cable according to CAT 6 or higher.

5.1.2

Settings for SINUMERIK solution line

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 via the X120 Ethernet socket, for an IPC/PCU, it is via the

"Ethernet 2" or "X2" or "X2 P1" 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 deviations from the

strict star topology.

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/IPC. The server ensures assignment of IP addresses to the Ethernet components in the

system network (DHCP clients) from a specified address band.

Operator panel front: OP 012

Manual, 05/2019, A5E36371591B AB

Networking

5.1 System settings

The following rules apply for assignment of IP addresses in the system network:

● For all NCUs and/or PCUs/IPCs, 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 by the DHCP server.

Its name is generated automatically (for MCP, MPP, HT 8), or is entered at commissioning

(TCU).

● If there are multiple NCUs, IPCs and/or PCUs in the system network, depending on the boot

sequence, the system automatically specifies the DHCP server and automatically ensures

synchronization of all necessary data, so that the next time the system boots any other NCU,

IPC, or PCU could take on the role of DHCP server. However it is better to specify a DHCP

master. This is an NCU, IPC, or PCU in the system network that is available on 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, IPC, or PCU can

take over this task, unless you deactivate this option in the DHCP configuration. All non-

master NCUs/IPCs/PCUs wait while the system boots for a preset time for the master to

become available.

Note

In a system network or on a boot server, i.e. on the NCU, IPC, or PCU that accommodates

the active DHCP server, a maximum of 30 operator stations may be operated

simultaneously with the 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/IPC can be connected via "Ethernet 1"

to a 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.

5.1.3

System boot with system network

System behavior at boot

The system boot behavior is based on the following principle:

● For the configuration of an NCU 7x0 with a PCU/IPC, the default for a network configuration

is as follows: The NCU keeps the default IP address 192.168.214.1 on X120, the PCU/IPC

keeps the default IP address 192.168.214.241 on Eth2.

● For a configuration of more than one NCU 7x0 without PCU/IPC, with one or morel PCUs/

IPCs, a distinction must be made between two cases:

- All address conflicts and DHCP conflicts are resolved automatically when booting and

the system is ready for operation. In this configuration there is no guarantee that all

NCUs and PCUs/IPCs will always receive the same IP address at each system boot.

- If the user requires all NCUs, and possibly also the PCU/IPC, to have a defined constant

IP address at each boot, for example, because the IP address is stated explicitly in the

PLC program, the user must configure a fixed IP address in the adapter settings in the

Windows Control Panel for each affected NCU 7x0/PCU/IPC.

● You can specify a DHCP master in the basesys.ini file.

● Assigning names:

- Assign meaningful names for all NCUs in the basesys.ini file otherwise the names will be

generated automatically.

- A PCU/IPC always has a computer name, which you can change if required.

● The IP addresses of the TCU, MCP/MPP, EKS, HT2, and HT8 are freely assigned within the

specified address range on each boot. MCP/MPP, HT2, and HT8 are identified in the PLC

via their DIP switch settings.

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/IPC, 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.

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/IPC on the system network or from a standard DHCP

server. The behavior of the TCU cannot be changed 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.

Pre-configuration of the PCU

A PCU has two Ethernet interfaces with default settings for use with SINUMERIK solution line:

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 connec-

tion to a system network. On Eth 2 the fixed IP address

5.1 System settings

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.

It is also possible to make the NCU a DHCP client. The configured IP address in basesys.ini is

a "requested" IP address, which is rejected in the case of an address conflict and replaced by

a dynamic IP from the address range.

In large system networks, it makes sense to set an NCU/PCU/IPC as the DHCP master. If an

additional 2-3 hosts are used (NCU/PCU/IPC), the user sets the DHCP priority to "ON_HIGH".

For the other hosts, the user sets DHCP priority to "ON_CLIENT_SYNC" or

"ON_CLIENT_NO_SYNC".

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.

The NCU has three Ethernet connections:

;

● X120 to connect to the system network with an active DHCP

server (Eth 0)

1&8

● X130 to connect to the company network as the standard

;

DHCP client (Eth 1)

● X127 as a service connection with an active DHCP server (Ibn

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

as Service input. 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.

● Direct keys cannot be triggered, i.e. the softkeys to the direct keys can be triggered in the

● There is no config.ini configuration file, as for a TCU, i.e. a configuration for a TCU is not

possible for such an operator control unit (power-up behavior, displacement, t:m:n);

however, the displacement mechanism on the external operator control units is effective.

● An external operator control unit is never signaled as active operator station in the PLC.

5.2.3

Displacement mechanism for TCUs

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 a

shadowing group. The remaining TCUs are switched to passive mode, which means they no

longer represent a load with regard 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.

4 active TCUs connected in parallel to PCU/IPC

Displacement rules

You configure the displacement mechanism in SINUMERIK Operate in the "Setup" operating

area > menu forward key > "OPs" softkey for the respective operator panel.

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, is in the monitoring mode and 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 powering up, the TCU always always attempts to establish the first connection. 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.

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.

Networking

5.2 Commissioning TCU

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 also assigned to the

first interface and byte DB19.DBB119 to the second. These bytes acquire the index of the

active TCU/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 TCU_INDEX field with the configured index to the TCU or PCU/IPC with

an OP that currently possesses user authorization in the shadow group. If no OP is active, a

value of 0 is entered in TCU_INDEX.

If no TCU index is configured for the active TCU/OP, the value 255 = undefined is transferred

as a TCU index. This means that the values 0 and 255 may not be configured as the TCU index.

Configuration

The TCU index is configured on the PCU/IPC in the same way as a machine control panel

address (MCP address). The TCU index is set in the "OP Properties" dialog of the "System

Network Center" program.

Operating principle

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."

5.2 Commissioning TCU

While this message is displayed, operations on the OP with the user authorization can still be

carried out unaffected.

Note

Active switching of an OP to another PCU/IPC is possible

The switchover disable only relates to changing the user authorization on the OPs in a

shadowing group on a PCU/IPC.

This means that active switching away from one OP to another PCU/IPC 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 under the following circumstances:

- If the OP in possession of the user authorization is actively switched to another PCU/IPC.

Depending on whether another TCU takes over the user authorization or whether no

TCU is currently active, the index of the TCU or the PCU/IPC itself (if its directly

connected OP becomes active) is entered, in exactly the same way as when there is a

switchover of user authorization.

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 group.

- If an m:n switchover is in progress. The HMI program of the incoming PCU/IPC

deactivates the HMI program which is active on it. Therefore, an OP from the shadow

group of the new (incoming) PCU/IPC must receive the user authorization. The TCU

index of this OP is entered in the TCU_INDEX field.

- If a PCU/IPC is disconnected from an 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/IPC, it can be deactivated there, i.e. it

does not receive user authorization if a switchover disable is set for the destination PCU/IPC.

● With an m:n PCU/IPC switchover - the PCU/IPC is switched to another NCK and, therefore,

to another PLC - the PCU/IPC accepts 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

At a TCU, which has no user authorization, press any key. The operating software does not

evaluate this key; this only serves to request user authorization.

Network configuration

5.3.1

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 of the respective TCU.

This separation is performed via the following specified 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/X2 of the PCU/IPC is preconfigured for connection to the system

network; while Ethernet interface Eth 1/X1 is used for connection to the company network.

● An NCU is connected to the company network via X130.

Meaning of the connections:

○

Eth 1/X1 as DHCP client

●

Eth 2/X2 as DHCP server

A direct Ethernet connection is used to connect a TCU to X120 of the NCU. NCU and TCU are

suitably preconfigured with IP addresses.

The IP addresses are not significant for further operation.

The TCU is connected to the NCU via a crossed Ethernet cable.

The direct connection of the NCU via X120 to the TCU automatically establishes a simple

The TCU is directly connected to the NCU via 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 the 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/configuration, the NCU is integrated

in 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

● The address of a DNS server

● The address of a gateway (default router)

The IP address of the NCU on this connection is also assigned via the 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.

In this configuration, a switch is also required for the system network. All components are

connected using straight Ethernet cables.

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 configuration on Eth 2, the PCU/IPC is assigned

a static IP address in the range 192.168.214.241 - 192.168.214.249 with a subnet mask

255.255.255.0 . The DHCP server of the NCU supplies the TCU with an IP address and serves

as a boot server for the TCU.

The observations made for configuration 2 apply here with regard to the connection to the

company network. The connection to a switch on the company network is made via a patch

cable for Ethernet.

To connect one TCU to both HMI systems you must create an additional connection to the NCU

for the TCU.

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.

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 VNC connections should be configured in the HMI.

● The boot server (active DHCP server) in the system network must be an NCU.

● This NCU must be integrated via X130 or X120, i.e. in the network that contains the

computer to be monitored.

Operator panel front: OP 012

Manual, 05/2019, A5E36371591B AB

Networking

5.3 Network configuration

● 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 observed computer must be adjusted to the characteristics of

the TCU. Otherwise the TCU scales the image it receives to match the display area

available to the TCU, which impairs the quality of the display on the TCU.

device for an older TCU or as new device on a software version older than 4.7 SP2.

●

"Screen Rotation" (0°/90°/180°/-90°/Auto)

Specifies in which angle the screen is to be rotated in the software. This is useful when the

panel is to be rotated during installation.

For the "Auto" setting, the rotation of the display is taken from the panel.

●
