Features:
- UR6021 rack architecture provides 21 slots for SIMATIC TDC processor, communication, and signal modules.
- A 64-bit backplane and eight defined P0 positions support high-speed and direct processor communication.
- The integrated power supply and replaceable fan assembly support dense cabinet-based TDC installations.
The current order configuration is the Siemens UR6021 rack identified by article number 6DD1682-0CH3, supplied as a 21-slot SIMATIC TDC rack assembly.
The rack provides the shared mechanical, power, cooling, and backplane infrastructure required for coordinated multiprocessor control.
Before selection or replacement, verify the CPU555 arrangement, P0 slot plan, power demand, grounding, fan access, and cabinet clearances.
Availability is subject to stock and configuration verification.

- Multiprocessor SIMATIC TDC control stations using coordinated CPU555 modules and shared rack resources.
- Large drive-control cabinets requiring synchronized processors, high-density module installation, and monitored cooling.
- Process-engineering and test systems that exchange control data through the TDC backplane and P0 connections.
- The 64-bit backplane provides high-speed data exchange between compatible modules installed in the UR6021 rack.
- Eight defined P0 positions support direct point-to-point communication between compatible CPU555 modules.
- Each CPU555 can communicate through the backplane with up to seven additional CPU555 modules in the documented configuration.
- The replaceable fan assembly includes monitoring and signaling functions for the rack cooling system.
- Rack status and fault indications support service checks before restarting or commissioning the configured TDC station.
- The integrated power section supports the rack’s module supply rails and coordinated control-system operation.
- The power supply provides separate high-current rails for +5 V, +3.3 V, +12 V, and −12 V module requirements.
- The documented continuous-load limit is 600 W at 60 °C and must be respected during rack configuration.
- Power-failure backup of at least 20 ms supports controlled behavior during short supply interruptions.
