Safety Integrated - Industry - Siemens

Setup and Wiring
In order to set up and wire the functional example, it is absolutely
necessary to consider the following note:
Warning!
In order to meet the requirements of Safety Category
4, it is obligatory to read back the process signal to the
actuator. Read back is not implemented in this example.
The actuator in this example is an indicator light simulating
a machine. If other actuators are used, read back
has to be ensured by the user. The Safety Integrated
Functional Example AS-FE-I-007-V10-EN provides a detailed
description of "Read back".
An overview of the hardware structure
The arrangement to implement the safety door consists of a
PROFIBUS configuration. A failsafe S7-CPU is used as DP master,
an ET 200S as DP slave. The yellow indicator light can be replaced
by actuators in accordance with their requirements.
Below, the wiring of conventional modules is shown only partly
to provide greater clarity.

Wiring of the hardware components
Requirements: The power supplies are supplied with 230V AC.
First check the addresses set at the hardware components
listed below:

Note
Can be changed
The PROFIsafe addresses are
automatically assigned during
configuring the failsafe
modules in STEP 7. The
PROFIsafe addresses 1 to
1022 are permissible. Please
make sure that the setting at
the address switch (DIL
switch) on the side of the
module corresponds to the
PROFIsafe address in the
hardware configuration of
STEP 7.
Note
The DP interface of the CPU 315F must be connected
with the DP interface of the IM 151 HF.
Note
The wiring of the hardware is illustrated below. In the
following table, the hardware components occurring
several times are numbered so they can be allocated in
the subsequent wiring plan.
