Example: Disabling Alarms
Example: Disabling Alarms
There are times when you may want to disable an alarm triggered by a tag or group of tags. This can easily be
accomplished by manipulating the tag’s AlrDisable field during runtime. The AlrDisable field is R/W, and if the
field is set to 0, any alarm associated with the tag is enabled. This means that if an alarm condition occurs, an
Alarm will be generated If the field is set to 1, any alarm associated with the tag is disabled. This means that if
an alarm condition occurs, an Alarm will not be generated.
You can read or manipulate (set) the AlrDisable filed by the following syntax:
From an IWS Math Script
Tag
AlrStatus
Expression
TagName->AlrDisable //returns the current Alarm disable status
TagName->AlrDisable 0 //enables Alarms from this tag
TagName->AlrDisable 1 //disables Alarms from this tag
From VBScript
$AlrStatus = $TagName-> AlrDisable
$TagName->AlrDisable = 0
$TagName->AlrDisable = 1
//returns the current Alarm disable status for this tag
//enables Alarms from this tag
//disables Alarms from this tag
