ET 200S Distributed I/O System
EWA-4NEB 780602402-12
Controlling a nd monitoring options
You can use the control feedback interface (PIQ) and feedback interface (PII) to
control and monitor the options with the user program.
Recommendation: Before you use the optional expansion of the ET 200S, check
using the feedback interface (see Table 3-10) whether all the configured electronic
modules are inserted.
Note
Using SFCs 14/15 it is possible to consistently access the control and feedback
interface.
The control and feedback interface is in the process image of the inputs and
outputs 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 with the ending ...O or ...SO in
the configuration software for that power module (see also Appendix C).
There is one bit for each slot of the
electronic or RESERVE modules in the
ET 200S.

Slots 2 to 63
Feedback interface:

Control interface PIQ (AB x to AB x+7):
Using these bytes (8 bytes) you can control the diagnostic behavior of the slots
you have enabled in HWCONFIG for option handling.
Only the bits of the slots you have enabled at parameter assignment for option
handling are evaluated (they are marked with ”0”).
