Cicode Function AlarmSetInfo

[Anonymous user]

Hi,

(Citect version: v8.10.0.2086)

I'm currently using AlarmSetInfo (INT AN, INT Type, STRING Value) to apply a priority filter using the following code:

FUNCTION AlarmFilteringToggleShowingEvents (INT iAN, STRING sCluster)
	INT hGrp = GrpOpen("Alarm_Group", 0);
	
	IF hGrp = AlarmGetInfo (iAN, 7, sCluster) THEN
		AlarmSetInfo(iAN, 8, 1);
		AlarmSetInfo(iAN, 7, 0);
	ELSE
		AlarmSetInfo(iAN, 8, 1);
		AlarmSetInfo(iAN, 7, hGrp);
	END;
END

Where "Alarm_Group" is a defined group of priorities.

The issue that I am having is that when this function is called it clears all other filters that are already applied to the alarm table. For example it clears the equipment filter that is applied.

Why does filtering by priority affect the equipment filter?

There is no information in the help for the AlarmSetInfo function that states that all currently applied filters will be removed when using this function.

It would make sense that all current filters are overriden if I was using AlarmFilterEditSet but this is not the case.

You are correct with your assumption  the function  AlarmSetInfo will overwrite other filters set by  AlarmSetInfo.  Its better to use the Alarm Filter Functions 

The following is a copy from the help for AlarmFilterEditSet function 

iHndl = AlarmFilterEditOpen(iAN);
iRet = AlarmFilterEditSet(iHndl,"Tag=Dig*;Category=1;Area=1;");
iRet = AlarmFilterEditAppend(iHndl, "Priority<20");
sRet = AlarmFilterEditFirst(iHndl); // Tag=Dig*;
sRet = AlarmFilterEditNext(iHndl); // Category=1;
sRet = AlarmFilterEditLast(iHndl); // Priority<20;
sRet = AlarmFilterEditPrev(iHndl); // Area=1;
iRet = AlarmFilterEditClose(iHndl);
