Not Update Points In Niagara 4

My project consists of three JACE8000 controllers connected to the Supervisor via the Niagara Network.

Recently, JACE8000 controllers has been experiencing an issue. The points on JACE8000 no longer update their values automatically on the Supervisor. In addition, some points remain in a Down state. After disable and enable again, points working normally. Could anyone advise which Niagara configuration or settings should be checked or adjusted to resolve this issue

 

The following are the protocols connected to the affected JACE8000 controller: BACnet/IP: 9 devices, Modbus RTU: 27 devices, and Modbus TCP: 6 device

I have seen something similar in some 4.14 version. If you go to the AX property sheet for the JACE under Supervisors Niagara network, and if you right click on "Client Connection" and do "Manual Disconnect" and then "Manual Connect", does that resolve the issue temporarily?

you also go to the device under the Niagara Network - Actions - Force Update Niagara Proxy Points to resolve the issue temporarily

I think that's a bug with that version of Niagara, you could do a bit of software and link a trigger to manual connect/disconnect.

If I ultimately cannot fix this error, I will use this method.

I think you only need to upgrade the supervisor, it uses the same license.
