Issue
When attempting to assign a foreign address to the Configurable Analog Input object in I/A Series R2 for BACnet use, the system generates a warning:
WARNING: Unable to export object: no BACnet equivalent object type for SpaceTemp [/B12B4_5/services/BACnetService]Product Line
TAC IA SeriesEnvironment
I/A Series R2
Cause
The native I/A Series R2 Analog Input object is designed to prevent passing NaN values from input to output, holding the last valid value instead.
Although the Configurable Analog Input object can be configured to pass NaN, it is not recognized as a native BACnet object. The BACnet module only supports native object types for foreign address mapping.
Although the Configurable Analog Input object can be configured to pass NaN, it is not recognized as a native BACnet object. The BACnet module only supports native object types for foreign address mapping.
Resolution
Only native I/A Series R2 objects (AI, AO, BI, BO, MSI, MSO, calendar, and schedule) can be exposed as BACnet points using the foreign address property.
To resolve the issue:
- Replace the ConfigurableAnalogInput object with a native AnalogInput object.
- Adjust the application logic accordingly to maintain functionality.
