Movicon Help on Line - Rel. 11.7.1301
When an alarm is not associated to an activation variable, "Alarm Variable" property, Movicon will control if a variable exists in the Real Time DB with the same alarm name in runtime. If a variable does exists with the same name, it will be used as the alarm's activation variable and therefore its value will be used for activating the alarm based on its threshold activation settings.
For instance, if an alarm has been defined as "Alarm01" without an activation variable associated to it and a variable called "Alarm01" exists in the Real Time DB, this variable will be used by the alarm as its activation variable.
In this case the alarm can also be associated as a template to other variables and result as a different alarm for each variable, one for the variable which has the same alarm name and one for each variable to which the alarm has been associated as a template.

When using alarms as templates, therefore without any associated activation variable, be careful not to define variables in the Real Time DB with the same name as the alarm's, otherwise a link to the variable with the same name of the alarm will be created in addition to the alarms as templates as well. |
