• Color depth: 18-bit
• 640 x 480 to 1280 x 1024 pixels
• Vibration-free mounting of the PCU/IPC in the control cabinet.
• Effective operation of larger machines.
• Signal transmission between PCU/NCU/IPC 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.
• Mixed operation of operator panel fronts connected via TCU and an operator panel front
connected directly to the PCU/IPC is possible.
• With restrictions to the interfaces (see Section "Operating the menu for a new TCU or
replacement TCU (Page 70)"), the TCU 30.3 is compatible to the previous models and
therefore mixed operation is possible.
TCU 30.3
Equipment Manual, 07/2025, A5E40874197B AE 21
Description
3.1 Overview
Compatibility
The TCU 30.3 is compatible with the following systems (also as spare part for the TCU, TCU 20.2
and TCU 30.2):
• SINUMERIK 840D sl:
– NCU 7X0.3(B) PN (>= CNC SW 2.7 SP3 HF10)
• Or SIMATIC IPC 427E for SINUMERIK, with PCU basic software
• Or SINUMERIK PCU 50.5 (Windows XP / Windows 7)
• Operator panel fronts:
– OP 010, OP 010C, OP 010S, OP 012, OP015, OP 015A, TP 015A, OP 019
Design
The TCUs are coupled via Ethernet as Thin Clients to the PCU/NCU/IPC in a dedicated subnetwork
(via DHCP server on the PCU/NCU/IPC).
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 Mbps can only be achieved with NCU 7x0.3B PN, IPC 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
receive lines of the Ethernet cable are crossed in the PHY. If, however, the partner does not
have "Autocrossover", a crossover cable is required.
