DiscrepancyTimeCh1_Ch3 input

Specification of the permissible discrepancy time for monitoring the equivalent switching operation at the inputs S_EnableSwitchCh1 and S_EnableSwitchCh3.

Data type: TIME

Initial value: #0ms

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

Background: As a result of mechanical influences, signals may have a tolerance when switching contacts. By specifying the DiscrepancyTimeCh1_Ch3 value, the time period is defined within which the switching operations at the inputs S_EnableSwitchCh1 and S_EnableSwitchCh3 must occur to be recognized as valid. This means both inputs can switch to SAFETRUE or SAFEFALSE within the set discrepancy time.

NOTE:

The switchover from SAFEFALSE to SAFETRUE is monitored for both inputs, as well as the switchover from SAFETRUE to SAFEFALSE.

NOTE:

If the discrepancy time is too short, the function block may enter the error state C030.

WARNING
	NON-CONFORMANCE TO SAFETY FUNCTION REQUIREMENTS Verify that the time value set at DiscrepancyTimeCh1_Ch3 corresponds to your risk analysis. Be sure that your risk analysis includes an evaluation for incorrectly setting the time value at the DiscrepancyTimeCh1_Ch3 parameter. Validate the overall safety-related function with regard to the set DiscrepancyTimeCh1_Ch3 value and thoroughly test the application. Failure to follow these instructions can result in death, serious injury, or equipment damage.
