  • 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.
Description
Siemens 6DD1682-0CH3 is the UR6021 rack for SIMATIC TDC multiprocessor control systems, providing the mechanical structure and internal interconnection required for a 21-slot control station. The rack is designed for organized installation of CPU, communication, and signal modules.

The assembly combines an integrated system power supply, a high-performance 64-bit backplane, and a replaceable fan unit for forced cooling. Eight defined P0 positions support direct communication between compatible CPU555 modules through the rack backplane.

Siemens 6DD1682-0CH3 is intended for large automation, drive-control, and process-engineering cabinets where synchronized processors, high module density, monitored cooling, and coordinated power distribution are required. Installation must follow the approved TDC slot plan, wiring arrangement, grounding method, and cabinet ventilation design.
