SIEMENS Operator panels SINUMERIK TCU 30.3

Thanks to its distributed structure, the SINUMERIK TCU 30.3 Thin Client Unit enables the operator panel fronts and the SINUMERIK PCU or SINUMERIK NCU to be installed separately. For this purpose, the user interface is copied to one or several operator panel fronts, each with a SINUMERIK TCU 30.3.


  • Efficient operation of larger machines using up to 5 identical operator panels simultaneously – of which 4 are thin clients
  • Efficient operation of linked machines through suppression, also more than four thin client operator panels can be connected
  • Design of flat operator panels through the shallow installation depth and low power dissipation.
  • Vibration-free mounting of the SINUMERIK PCU 50.5 or the SIMATIC IPC 427E in the control cabinet


The SINUMERIK TCU 30.3 is coupled via Industrial Ethernet as a Thin Client in a dedicated subnet via DHCP server to the SINUMERIK PCU/NCU or the SIMATIC IPC.


  • Resolution 1280 × 1042 pixels (SXGA)
  • Color depth 32 bit


  • 4 × USB 2.0 type A at front, for connecting mouse, keyboard and USB flash drive
  • 1 × Industrial Ethernet 10/100/1000 Mbit/s (RJ45 front socket)


  • Signal transmission between SINUMERIK PCU/SIMATIC IPC, SINUMERIK NCU and operator panel front via Industrial Ethernet
  • Easy installation and service-friendly layout thanks to the component structure
  • Functionality of the SINUMERIK PCU or the SIMATIC IPC is the same as in a centralized configuration, e.g. number of PCI slots. The same operating screen is shown synchronously on all operator panel fronts and can be operated from all panel fronts. Operator inputs on a thin client have equal priority with operator inputs on an operator panel directly connected to the SINUMERIK PCU. The operator panel in passive mode shows a darkened screen.
  • Operation is possible on the active operator panel. An enabling function permits a passive operator panel to request operation.
  • The combined operation of operator panel fronts on a SINUMERIK TCU or with an integral TCU and an operator panel front directly connected to the SINUMERIK PCU is possible.
  • The distance to the operator panel fronts is determined by the maximum distance between two network nodes/access points (100 m/328 ft).
