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 working with the ET 200S optional enhancements, check whether
all the configured electronic modules are plugged in using the feedback interface (refer to the
table below).
Note
SFCs 14/15 can be used to consistently access the control and feedback interface.
