2.5 Self Test
Apart from checking the word clock signals and the signals of the real-time reference, the
module performs a self test.
The following errors will be indicated at the
System
page of the status monitor:
Chapter ‘
Overview of Error Indications at the Status Monitor
’ describes the meaning of
status
,
counts
,
fail
, and
disabled
.
‘
power on
’
: After the power has turned on, the non-volatile data will be checked for
plausibility, for example regarding the set-up of the module. In case of any
implausibility, a
‘
power on
’
error will be indicated.
‘
relays
’
: The latching relays can be monitored through internal sense signals. If any sense
signal does not correspond to the intended switching position, a
‘
relays
’
error will be
indicated.
Each error has the following consequences:
•
Indication of an error at the status monitor (‘
status
’ = 1).
•
In case of error ‘
relays
’:
Error counter counts one up.
•
Counter ‘
overall errors
’ counts one up.
•
LED programmed as ‘
Switc
her Error’
lights up (RUB1 version modules).
•
GPO programmed as ‘
System Error
’ becomes active.
•
SNMP trap ‘
System Error
’ will be
sent.
Each error has additional the following consequences if the corresponding ‘
disable
’ checkbox
has not been checked:
•
Indicati
on of a failure at the status monitor (‘
fail
’ = 1).
•
Counter ‘
overall failures
’ counts one up.
•
Lamp programmed as ‘
Fail’
lights up (RUB1 version modules).
•
GPO programmed as ‘
System Failure
’ becomes active.
•
SNMP trap ‘
System Failure
’ will be sent.
•
