Syntax

system.tag.editAlarmConfig(tagPaths, alarmConfig)

Parameters

String[] tagPaths - The full path to the tag you want to edit. Note: you can specify the tag provider name in square brackets at the beginning of the parentPath string. Example: "[myTagProvider]MyTagsFolder". If the tag provider name is left off then the project default provider will be used.

PyDictionary alarmConfig - A dictionary of multi-dimensional lists containing the new alarm configuration. The key in the dictionary will be the name of the alarm being to edit, and the value is a list of lists. The nested lists use the format ["name", "Value", "newValue"]. Note that item 1 is always "Value".

Example: {"targetAlarm":[["propertyToChange","Value","newValue"],["anotherProperty","Value","anotherNewValue"]]}

If the name of the alarm does not match a pre-existing alarm, a new alarm will be created. Note that alarm names are case sensitive. Beware of typos.

A list of scripting names for each alarm property can be found on the Tag Properties page.

Returns

nothing

Scope

Code Examples

Code Snippet - Single Tag, Multiple properties

# The following example will alter the alarm configuration on a single tag. 
# The tag currently has an alarm named "High Temp". The code below will change the name of the alarm
# to "Low Temp", and change the Setpoint to 100.
 
# Build a list of tag paths. Only a single tag will be altered, so create a list of one item and store the list in a variable
tagPaths = ["sensors/B3:0"]
 
# Build the dictionary of alarm names, and properties to change. 
alarmConfig = {"High Temp":[["name","Value","Low Temp"],["setpointA","Value","100"]]}
 
# Edit the alarm configuration. 
system.tag.editAlarmConfig(tagPaths, alarmConfig)

Code Snippet - Multiple Tags, Single Alarm per Tag

# The following example will disable alarms on multiple tags.
# The tags below both have an alarm named "Alarm"
#This code will edit the Enabled property for both alarms. 
 
# Build a list of tag paths. 
tagPaths = ["Tanks/Tank_1/level_PV", "Tanks/Tank_2/level_PV"]
 
# Build a dictionary of alarms. Both alarms have the name "Alarm", so a dictionary of one item
# will be able to alter both alarms in a single call.
alarmConfig = {"Alarm":[["enabled","Value","0"]]}
 
# Edit the alarm configuration.
system.tag.editAlarmConfig(tagPaths, alarmConfig)

Code Snippet - Multiple Tags, Multiple Alarms per Tag

# The following example will create two alarms each on two different tags. 
# The code assumes there are not pre-existing alarms on the tags by the name of "High Level" and "Low Level"
# The Name, Mode, and Setpoint properties will be modified for each alarm.
 
# Build a list of tag paths.
tagPaths = ["Tanks/Tank_1/level_PV","Tanks/Tank_2/level_PV"]
 
# Configure two alarms on the tags.
# Mode value of 2 = Above Setpoint
# Mode value of 3 = Below Setpoint
alarmConfig = {"High Level":[["mode","Value","2"],["setpointA","Value",80]], "Low Level":[["mode","Value","3"],["setpointA","Value",15]]}
 
# Edit the alarm configuration.
system.tag.editAlarmConfig(tagPaths, alarmConfig)
