Flowchart

The flowchart illustrates the function process of the safety functional

example.

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”.
