Controlling And Monitoring Options Without Reserve Modules - Siemens SIMATIC IM151-1 STANDARD Manual

Controlling and monitoring options without RESERVE modules

64B
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 required electronic modules are plugged in using the feedback interface (refer to the
table below). The contents of the feedback interface have to agree with the specifications of
the control interface.
Note
The use of SFCs 14/15 enables consistent access to 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 modules. 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 module slot:
● Control interface: Slots 1 to 63
● Feedback interface: Slots 1 to 63
