MaxMutingTime input

Specification of the maximum permissible time for the entire muting operation. If the muting operation is not completed within this time, the S_AOPD_Out output is switched to the defined safe state SAFEFALSE and the function block signals an error (Error switches to TRUE).

Data type: TIME
Initial value: #0ms

Connection: Connect this input to a time literal, i.e., to a constant of the data type TIME.

This timer starts when at least one of the two muting sensors provides a SAFETRUE signal (i.e., there is an object inside the detection area of the sensor).

The muting operation is complete when at least one of the muting sensors provides SAFEFALSE again.

Further Info
Also refer to the example muting operation procedure shown in the functional description for this function block.

WARNING
Non-conformance to safety function requirements
  • Verify that the time value set at MaxMutingTime corresponds to your risk analysis.
  • Be sure that your risk analysis includes an evaluation for incorrectly setting the time value for the MaxMutingTime parameter.
  • Validate the overall safety-related function with regard to the set MaxMutingTime value and thoroughly test the application.

Minimum value: 0 s
Maximum value: 600 s
