Error Code: BACnet Error Class and Error Code

Solution

When a write operation fails in Niagara BACnet, the write status displays descriptive text in a colon-separated format containing the Error Class and Error Code returned by the device. For example, 'Property:Write Access Denied' indicates you attempted to write to a read-only property. Check that the proxy point type matches the BACnet object (e.g., don't use NumericWritable for an Analog_Input object). Verify the property is writable on the target device. Review the BACnet Error Class and Error Code in the device documentation to understand the specific error and correct the configuration accordingly.
