Siemens 6DD1662-0AB0 SIMADYN D CS7 communication support module

Siemens 6DD1662-0AB0 SIMADYN D CS7 communication support module is documented for the stated industrial system role.

System function

Rebuilt from individual evidence

System position

Evidence and limits

The captured exact-reference evidence identifies 6DD1662-0AB0 as SIMADYN D CS7 communication support module.

The documented function of 6DD1662-0AB0 is to routes serial communication for supported SS4, SS5 and SS52 modules using DUST, USS or PROFIBUS protocols.

The system position is an explicit inference from the exact-reference evidence.

Unknown: current unit condition, installation-specific compatibility, firmware or software version, and commercial availability.

System role

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

Function: Routes serial communication for supported SS4, SS5 and SS52 modules using DUST, USS or PROFIBUS protocols.
System position: Inferred system position: Sits between installed communication modules and the SIMADYN D L bus or CPU context.
Upstream / inputs: Receives serial protocol data from supported communication modules from the upstream system.
Downstream / outputs: Provides communication data on the SIMADYN D L bus to the downstream system.
Limitations: Unknown: current unit condition, installation-specific compatibility, firmware or software version, and commercial availability.
