Issue
IP Controller is getting incorrect overrides at Priority 16. The room control unit is writing to Priority 16 which is then writing to multiple setpoints with a zero (0) value in the function block program, causing programming to fail.
Product Line
EcoStruxure Building Operation
Environment
- Building Operation Workstation
- Building Operation Automation Server
Cause
Even though priority 16 and the Value can sometimes be synonymous, they are still separate Objects
The room control unit is writing to Priority 16 AND the Value has been set to Zero.
- The value is set to 0
- Writing directly to priority 16 from the room control unit
Resolution
The best practice would be to:
- Bind to the Value Object from the room control unit and also set the retain level under Value rather than biding to and setting Retain level on Priority 16
