TAB: Events

 

 

The Event TAB allows you to associate functions or script code with tag events.

 

OnValueChanged: event that is raised if the tag has a different value from the previous one

OnValidBed: event that is raised every time a new value is read by the PLC

OnValoreScritto: event that is raised when the tag value is written from any source

OnValueSetted: event that is raised when the tag value is written by Crew

OnOnLine: event that is raised once when communication with the PLC is activated (for example when the communication cable is reconnected)

OnOffLine: event that is raised once when communication with the PLC fails

 

The lower part of the window contains a series of events that are displayed when the management of thresholds and limits is enabled in the tag
