Niagara Points Keep Faulting – Orange Proxy Extensions

Problem

Points in Niagara repeatedly go "orange" (fault) in the Workbench view, especially after an override is released or network interruptions occur. Point value shows but status indicator remains faulted even though the device is responding.

Root Cause

Communication delays, stale data from missed polling cycles, or residual fault state in the proxy extension buffer that hasn't been cleared.

Solution

1. Open the property sheet for the orange point in Workbench

2. Expand the Proxy Extension section and read the fault cause (communication error, write/read timeout, stale status)

3. Depending on the cause:

   • For stale status: Verify network integrity (BACnet/IP connectivity, MS/TP wiring/terminations), increase polling interval, or force a read by clicking the point's "Request Value" button
   • For communication timeouts: Check baud rates match device specs, verify no duplicate MAC addresses on the network segment, and power-cycle the device
   • For lingering override faults: Right-click the point → Release Override to clear any stuck command state

4. If the fault persists after these steps, verify the underlying device is actually responding and not in a fault state of its own
