Description

Introduction:


The Datalogging and Supervisory Control Module adds the alarming functionality to network-published shared variables.  The alarm levels can typically be configured through the Alarming Page of the Shared Variable Properties Dialog Box.  However, using the property node seen in this example, the alarm levels can be changed during run-time.

 

Steps to run:

3) Then change the alarm levels and select Update Alarm Levels.

4) Repeat step #2 with the new alarm levels.

5) Select STOP

How this can be done inside .EXE ? As we can see in the documentation this operation is not supported on run-time system (.EXE)
