is set if:
• A sensor test was not executed in the
case of an active startup test function
• A discrepancy condition violation is
present
• The value "1" is not present simultane‐
ously at all available (parameterized)
function inputs (IN1, ...)
• A signal sequence violation is present
• A cross-circuit is present in the case of
cross-circuit monitoring

is set if:
• After the discrepancy time has elapsed, the
signal states at the inputs monitored are dif‐

• The signal states of the inputs monitored
had not all previously been reset simultane‐
