Meaning
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
Meaning
This message is set in a parameterized startup
test on each restart and each time the substitute
value is changed to a real value until the con‐
nected sensor is actuated at least once.
is set if:
• After the discrepancy time has elapsed, the
signal states at the inputs monitored are dif‐
ferent
• The signal states of the inputs monitored
had not all previously been reset simultane‐
ously to the value "0" when they are set to "1"
The safety sensor has been actuated.
A cross-circuit was detected at input 1.
A cross-circuit was detected at input 2.
Only with start type "Monitored start":
The start signal time monitoring element detec‐
ted a violation.
