DiscrepancyTime input
Specification of the permissible discrepancy time for monitoring the switching operation at the S_ChannelNC and S_ChannelNO inputs.
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 DiscrepancyTime value, the time period is defined within which the switching operations at the inputs S_ChannelNC and S_ChannelNO must occur to be recognized as simultaneous. 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. |
