Controlling And Monitoring Options Without Reserve Modules - Siemens SIMATIC ET 200S IM151-1 FO STANDARD Manual

Behavior during the first start-up
In the case of option handling without RESERVE modules, the IM151-1 FO STANDARD
always goes into cyclic data exchange during initial startup. However, the I/O device
input/output is not activated until valid information about the options is available from the
module. No fault is indicated externally in this state (BF LED does not light up). The
input/output of the I/O devices is not active in this state. Evaluate the data of the feedback
interface in order to assess this state.
Behavior during a warm restart
Valid information about the options is stored retentively in the IM151-1. During warm restart,
the IM151-1FO STANDARD enters cyclic data exchange and the input/output of the I/O
devices is activated immediately. Has the configuration changed since the last startup (e.g.:
incorrect module plugged in or information about options is incorrect), the input/output of the
I/O devices is deactivated (irrespective of the parameter "Mode with set <> actual setup")
until the real configuration agrees again with the configured one.

Controlling and monitoring options without 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 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
