Limit value process alarms
If a limit value is infringed then the priority specified for the limit value alarm will be checked before
the limit value violation is communicated to the fieldbus host system. The priority that specifies the
action in the event of an active limit value violation is determined by the following parameters:
– HI_HI_PRI
– HI_PRI
– LO_LO_PRI
– LO_PRI
The status of the limit value process alarms is communicated to the fieldbus host system via the
following parameters:
– HI_HI_ALM
– HI_ALM
– LO_LO_ALMI
– LO_ALM
If the option of a limit value process alarm has not been enabled in the parameter ACK_OPTION
then this must be acknowledged directly in its parameter (see list).
Note!
The parameter ALARM_SUM shows the current status of all the process alarms.
