3.2.5 Controlling and monitoring options with RESERVE modules
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.
Principle
The control and feedback interface is located in the input and output process image of the
PM-E 24..48 VDC or PM-E 24..48 VDC/24..230 VAC power module. It can only be accessed
if entries ending in ...O or ...SO for that power module were selected in the configuration
software.
One bit is available for each ET 200S electronic or RESERVE module slot.
● Control interface: Slot 2 to 63
● Feedback interface: Slot 1 to 63
