Fundamental safety instructions
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.

Description
2.1 Overview
A Thin Client Unit (TCU) allows the spatial separation between an operator panel (OP) / touch
panel (TP) and the Panel Control Unit (PCU) / Numerical Control Unit (NCU). For this reason,
the user interface is copied to one/several operator panel fronts, each with a TCU.
Validity
The description applies to the following TCU:
Designation Article number
Thin Client Unit 30.3 6FC5312-0DA00-1AA1
Features
● Implementation of flat operator panels through the shallow installation depth and low power
loss.
● Color depth: 32 bits
2
Preconditions
● 640 x 480 to 1280 x 1024 pixels
● Vibration-free mounting of the PCU in the control cabinet.
● Effective operation of larger machines.
● Signal transmission between PCU/NCU and operator panel via Industrial Ethernet
The distance of the components is determined by the maximum distance between two
network nodes / access points (100 m).
● The same operating screen is shown synchronously on all operator panel fronts and can
be operated from all operator panel fronts.
● The operation on an operator panel front connected via TCU has the same access rights
as the operation on an operator panel front connected directly to the PCU.
● The mixed operation of operator panel fronts connected via TCU and an operator panel
front connected directly to the PCU is possible.
● With restrictions to the interfaces (see Section "Operating the menu for a new TCU or
replacement TCU (Page 60)"), the TCU 30.3 is compatible to the previous models and
therefore mixed operation is possible.

Description
2.2 Configurations
Design
The TCUs are coupled via Ethernet as Thin Clients in a dedicated subnetwork (via DHCP
server on the PCU/NCU) to the PCU/NCU.
Interfaces:
● 4 x USB 2.0 Hi-Speed to connect the mouse, keyboard and USB flash drive
● Ethernet 10/100/1000 Mbit/s
The transmission rate in Ethernet system networks automatically sets itself to the maximum
possible value. 1000 Mbit/s can only be achieved with NCU 7x0.3B PN and PCU 50.5 (if a
PCU is required).
Note
The Ethernet interface has so-called Auto MDI-X functionality. If required, the send and

Before assembling the two components, the interface cables of the operator panel front (IO/
USB cable K1, K2 display cable and, if necessary, K3) must be inserted into the corresponding
socket of the TCU (visible behind the housing cut-out).
Note
Since some of the interfaces do not have a cable strain relief for the cables to be connected,
it is recommended to secure the cables to the u-shaped lugs on the supporting plate using
cable ties.
WARNING
Electric shock in the event of an individual error when grounding is insufficient
If the panel is installed in an environment with hazardous voltages with insufficient grounding,
this may cause an electric shock in the event of an individual error, which can lead to death,
serious injury and property damage.
To prevent electric shocks, sufficiently ground the conductive parts of the panel according to
the nationally applicable regulations. To do this, use the relevant fuse ratings of the circuits
with hazardous voltages for the possible individual error scenarios as the basis for
dimensioning the protective conductor connection.

WARNING
Parasitic voltage
If the device is installed in an environment with higher / more hazardous voltages with
insufficient insulation, parasitic voltages can lead to death, serious injury and property
damage.
To prevent parasitic voltages, insulate the cables corresponding to the highest voltage that
will be dealt with.
The safety of a system with an integrated TCU with operator panel front is the responsibility
of the system installer.
Observe all relevant information from this manual regarding the mounting of the chosen
operator panel front.
The mounting at the installation site is performed in accordance with the instructions of the
chosen operator panel front.

Connection
4.1 Pin assignment of the interfaces
In principle, USB interfaces have the following characteristics:
● Integrated power supply up to 500 mA for each socket.
● Maximum cable length 3 m (Length including the supply cable to the hub and the connected
terminal device; only 1 hub is permitted. It should be noted that some keyboards already
have a hub.)
Note
Cables that are too long can result in malfunctions or faults on the screen
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.
Note
Correct identification is only guaranteed for USB I/Os that comply to 100% with the USB
specification.

USB sticks
If you want to connect a USB stick to the USB interface, preferably use the tested SIMATIC
USB stick 16 GB for this purpose (Article No.: 6ES7648-0DC60-0AA0). Alternatively, you can
use a USB stick with any memory size. It must, however, meet the following minimum
requirements:
● File system: FAT16 or FAT32
● Partitioning: only in PC partition format (MBR)
USB sticks that deviate from these requirements have not been tested and may not be
recognized by the NCU.
