HB100E - CPU - Rev. 12/12
During a process alarm is processed by the CPU a diagnostic alarm can be
released (if activated with Process+Diagnostic alarm) by the same event at
the same channel.
This interrupts the current process alarm execution in OB40 and branches to
OB82 for processing the diagnostic alarm (incoming). This OB allows you
with an according programming to monitor detailed diagnostic information
via the SFCs 51 and 59 and to react to it. If during the diagnostic alarm
execution further events at other channels occur that may also initialize a
process res. diagnostic alarm, these are temporarily stored. After finishing
the current diagnostic alarm execution, the sum diagnostic message
"process alarm lost" informs the CPU that in the meantime other process
alarms has occurred. After the execution of the OB 82 the user application
processing is continued. The diagnostic data is consistent until leaving the
OB 82.
After error correction automatically a diagnostic (going) occurs if the
diagnostic alarm release is still active.
In the following the record sets for diagnostic (incoming) and diagnostic
(going) are specified:
