Controlling and monitoring options

Introduction
You can use the control interface (PIQ) and feedback interface (PII) to control and monitor
options by means of the user program.
Recommendation: Before you work with the optional enhancements of the ET 200S, check
via the feedback interface (see table further below) whether all configured electronic
modules are plugged in.
Note
The use of SFCs 14/15 enables consistent accesses to the control and feedback interface.
Principle
The control and feedback interface is in the process output and input image of the PM-E
24 ..48 VDC or PM E-24 ..48 VDC/24 ..230 VAC power modules. It is only available if you
have selected the entries ending in ...O or ...SO for the relevant power module in the
configuration software.
There is one bit for each slot of the electronic or RESERVE modules of the ET 200S.
• Control interface: Slot 2 to 63
• Feedback interface: Slot 1 to 63
