This is the time for a cycle. The PLC program
performs one complete run.
Depending on event-controlled branchings in
the program this can take longer or shorter.

Diagnostic Coverage
Diagnostic coverage is the measure of the
effectiveness of diagnostics as the ratio
between the failure rate of detected dangerous
failures and the failure rate of total dangerous
failures:
Formula: DC = failure rate detected dangerous failures /
total dangerous failures
Designation
none
low
medium
high
Table: Diagnostic coverage DC
An accuracy of 5 % is assumed for the limit
values shown in the table.
Diagnostic coverage can be determined for the
whole safety-related system or for only parts of
the safety-related system.
Range
DC < 60 %
60 % < DC < 90 %
90 % < DC < 99 %
99 % < DC
