Configured alarm state for discrete alarm. Alarm State is the state or value of a Discrete Tag that is considered abnormal or in Alarm. .ALMDIG allows this to be edited from View. If Reflect On Line changes to Database is enabled, changes to .ALMDIG will be saved in the Configuration Database on the Project Node (i.e. become permanent).
Two-State Digital Tags
For Tags with Bit Length = 1 (i.e. Digital, ON/OFF or Two State Tags), Only this State will be in alarm.
For example, in an 2-state Digital Tag with an alarm state of 0, only State 0 is alarm; State 1 is normal.
Three or more State Discrete Tags
For Tags with Bit Length >= 2 (i.e. Discrete or Multi-State Tags), any state Greater Than or Equal to the Alarm State will be in alarm. For example, in an 2-state Digital Tag with an alarm state of 0, only State 0 is alarm; State 1 is normal.
For example, in an 8-state Discrete Tag, an alarm state of 6, only State 6 is alarm; State 5 is normal; State 7 is also normal.
