Issue
In Chapter 5 of the Niagara R2 Modbus integration manual, the following note describes the JDE "View Cache":
... After viewing linked Gx objects in JDE, polling will continue for the associated shadow objects in PollOnDemand containers until that view is removed from the view cache. Typically, this means 4 view changes before polling stops...
In an effort to reduce the number of shadow objects being polled (on a large job), can the 4 view changes, that are cached, be reduced to zero?
Product Line
TAC IA Series
Environment
Niagara R2 Modbus
Cause
The 4 view changes are by design.
Resolution
There is no way to configure the number of view changes or manually clear the cache. Closing the JDE and re-opening it is the only way to stop the values from updating.
