System role

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

Function: Controls the documented S7-200 machine sequence using its integrated I/O and communication ports.
System position: Sits in the controller signal path between field devices or power connections and the CPU processing program.
Upstream / inputs: Receives the documented AC power, program and field connections used by the S7-200 controller.
Downstream / outputs: Sends the documented control decisions through its integrated outputs and communication ports.
Limitations: Unknown: Installation-specific compatibility, wiring, firmware, project configuration, condition and commercial status were not captured.
