FB_BA_AlarmPlt
The function block collects the alarms of a plant and pools them in a group alarm.
The alarms are generated within the plant-related templates by the function block FB_BA_Alarm.
The alarms are allocated to a plant via the plant number.
The alarms are prioritised/weighted in the alarm output function block FB_BA_Alarm through the input byPrio.
It is important that the group alarm function block FB_BA_AlarmPlt and the alarm output function blocks FB_BA_Alarm within the templates of a plant are set to the same plant number!
The plant number can be assigned in the Project Builder in the parameter menu for the templates or via a column in the Excel import.
Inputs/outputs
VAR_INPUT
byPltId : BYTE;
sName : STRING;
bAck : BOOL;
byPltId: Number of the corresponding plant. Important: All templates of plant must be assigned to the same plant number in the PLC!
sName: Input field for the plant ID (configurable via Project Builder or Excel import)
bAck: Input for alarm acknowledgement of the plant. This acknowledgement is internally passed to the alarm output function blocks FB_BA_Alarm.
VAR_OUTPUT
bCriticalAlm : BOOL;
bNewAlm : BOOL;
bInAlm : BOOL;
bCriticalAlm: critical alarm. This is used in the templates for switching off a plant. To this end, the input byPrio in the alarm output function block FB_BA_Alarm must have the value 4.
