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 No. 7 „Integration of the
Readback Signal in an Application of Category 4 acc.
to EN 954-1“ provides a detailed description of "Read
back".
An overview of the hardware structure
The arrangement to implement the safety door interlock consists
of a PROFIBUS configuration. A failsafe S7-CPU is used as
DP master, an ET 200S as DP slave. Below, the wiring of conventional
modules is shown only partly to provide greater clarity.

Warning!
A speed or standstill monitor for monitoring hazardous
slowing down of a machine is simulated in this
example with a button (NO) which is connected as
single-channel to the failsafe input module (F-DI).
When using real speed or standstill monitors they
must be connected to the F-DI as double-channels
(1oo2 evaluation).
Note
The "high feature" electronic modules can also be replaced
by standard modules.
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:
Hardware

Adress
to be set
6 (PROFIBUS address)
F-DI Switch position:
1111111110
F-DO Switch position:
1111111101
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.
