System role

This section explains what the product does and where it acts in the surrounding system.

Function: Supplies and hosts SIMATIC TDC modules in a 21-slot rack boundary with an integrated fan for GDM use.
System position: Inferred system position: Sits between the system power or backplane context and inserted SIMATIC TDC modules.
Upstream / inputs: Receives system power and inserted TDC module connections from the upstream system.
Downstream / outputs: Provides 21 powered TDC module slots and GDM rack context to the downstream system.
Limitations: Unknown: current unit condition, installation-specific compatibility, firmware or software version, and commercial availability.
