Niagara N4: Write Fault - Property Write Access Denied

Error

Software Version: Niagara N4

Error Code: Write Fault: Property:Write Access Denied

Solution

Remap the points as unwriteable. Alternatively, you can change the 'present value' field to '3113' instead. This is a common workaround when integrating to third-party systems via BACnet, N2, or LGACP where a point incorrectly generates write faults even when no writes are being performed.
