4 Setup and Wiring
In order to set up and wire the safety functional example, it is absolutely
necessary to consider the following note:
NOTICE
In order to meet the requirements of category 3 / SIL 2, it is
obligatory for certain actuators (e.g. contactor) to read back the
process signal to the actuator.
Read-back is not implemented in this safety functional example. The
actuator is an indicator light simulating a machine. When using
different actuators, the feedback circuits have to be integrated and
evaluated by the user. Safety functional example 7 provides a
detailed description of “Read back”.
