Control Connection attribute for properties visible in PG2
I want to build a Graphic Display where we would like to present the values of Update Rate and Write permission for specific control connection properties. How could this be done, since there seems to be no function in PG2 or property-attributes to connect to graphic primitives?
Afaik, the update rate can not be queried.
Most graphics should use the default rate as declared by the Control Connection aspect but can override by declaring a non-zero Subscription Rate on the base properties of a PG2 graphic display. Some connect families have preferred update rates (e.g. 1, 3 or 9 seconds for 800xA for Advant Master) that should be adhered to for performance reasons.
Write permission can be read from the IsWritable subproperty of any OPC item. E.g.
