Example

The .AlarmROCInhibitor dotfield is used by setting .Name to an Indirect tag that is equal to the value of the .AlarmROCInhibitor tag then manipulating the value of the Indirect tag. The following statement returns the name of the alarm inhibitor tag for a rate-of-change alarm limit (assuming SomeIndirectTag is an analog indirect tag):

SomeIndirectTag.Name = AlarmedTag.AlarmROCInhibitor;

The inhibition state of the alarmed tag can be controlled by setting the value of the Indirect tag as follows:

SomeIndirectTag = 1;

Turns on inhibition
Rate-of-change alarms are disabled for AlarmedTag

SomeIndirectTag = 0;

Turns off inhibition
Rate-of-change alarms can be generated for AlarmedTag
