Non-safety-relevant tasks
Certain inputs/outputs of safety function blocks can be
connected in the safety circuit diagram or also in the
standard circuit diagram. The device safety inputs can also
be read and processed in the standard circuit diagram. The
result is output via safety outputs which however, CANNOT
be used in the safety circuit diagram.
An internal management function prevents the accidental
double use of these outputs (QS.., QR..).
The safety circuit diagram cannot access the data of the
standard circuit diagram in order to prevent the processing
of non-safety data in the safety circuit diagram.
Conversely, the standard circuit diagram only has indirect
access to the safety circuit diagram. In the standard circuit
diagram you can therefore:
• use diagnostic function blocks to evaluate signals of the
non-safety diagnostic outputs of the safety function
blocks,
• evaluate the error contact ER of a safety function block for
signalling a general fault,
• activate or deactivate safety function blocks as required,
The relationship between the safety and standard circuit
diagram must observe the rules specified for the creation of
safety circuit diagrams (
rules are observed by choosing the SAFETY TEST menu
option.

Danger!
Device outputs (QS., QR.) that are used in the standard
circuit diagram are not safety outputs and must only be
used for standard tasks. Make sure that these outputs do
not trigger any safety-related actions on the machine or
plant.
