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 emergency stop functionality
consists of a PROFIBUS configuration. A failsafe S7-CPU is
used as DP master, an ET 200M as DP slave. The ideally used
indicator light simulates the hazardous "machine". The indicator
light can be replaced by actuators in accordance with their
requirements.

DI (SM326) 8 You can change
the address areas
of the module
via inputs
(DIL button at
the back of the
module).
Please note the
following:
During safety
operation, input
and output address
have to be
identical,
divisible by 8
and they must
have a value
between 8 and
8176 (see
screenshot).

Note
The DP interface of the CPU 315F must be connected
with the DP interface of the IM 153-2.
