Principle of Alarm handling
Many of the System 200V modules are able to set an alarm (all non digital
modules, e.g. analog modules, function modules, fieldbus masters).
As soon as one or more modules report an alarm, the alarm data of the
appropriate slot location is received and acknowledged by the ethernet
coupler.
After that the slot location assigned bit of the internal
alarm information
image
is set and the diagnostic data with the length of 16Byte is stored.
In system 200V we distinguish between two types of alarms: the
process
alarm
and the
diagnosis alarm.
A module will set only one of the alarm
types at a time.
For differentiation, the alarm information image contains one 32bit wide
field (bit 0 = slot 0 up to bit 31 = slot 31) called process alarm status and
one 32bit wide field called diagnosis alarm status. After that, there follows
for each slot 0 ... 31 a 16byte wide field called alarmdata.
For acknowledgement you can also access diagnostic and process alarm
status writing. The 16byte alarmdata is read only.
The
alarm information image
with a size of 520Byte is placed behind the
256Byte I/O data and has the following structure:
32Bit process alarm status (little endian formatted):
Bit 0 = slot 0 ... Bit 31 = slot 31
32Bit diagnosis alarm status (little endian formatted):
Bit 0 = slot 0 ... Bit 31 = slot 31
16Byte alarmdata of slot 0
16Byte alarmdata of slot 1
... etc.
16Byte alarmdata of slot 31
Web-Server
All alarm capable modules feature the entry "Diag=" with the latest 16byte
of alarmdata. With an alarm set, the message "DiagAlarm" for diagnosis
alarm resp. "ProcAlarm" for process alarm is displayed.
