You can create scripts that use dotfields to dismiss all alarms that are in LATCHED state.

Category

Alarms

Usage

TagName.Dismiss=1;

Parameter

TagName

Any discrete, integer, real, indirect discrete and analog tag, or alarm group.

Remarks

Set this dotfield to a value of 1 to dismiss any outstanding alarms associated with a specified tag or alarm group. When the specified tag is an alarm group, all LATCHED alarms associated with the tags within the specified group are dismissed. When the specified tag is of any type other than alarm group, only the LATCHED alarm associated with that tag is dismissed. Setting the .Dismiss dotfield to a value other than 1 has no meaning.

Data Type

Discrete (read/write)

Valid Values

1

Example

The following statement dismisses an alarm associated with the Tag1 tag:

Tag1.Dismiss=1;

This next example would be used to dismiss all LATCHED alarms within the PumpStation alarm group:

PumpStation.Dismiss=1;
