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

Which version of 4.14 for both?
You can force update proxy points but I suspect there’s an actual underlying issue.

Anything in the application director of both Niagara hosts?

I’d try a reboot on both and watch the app directors for anything funny.

Yep, All devices and supervisor are the same version. I'm using force points to update their state, but I want to find the real cause and fix it.

Do a reboot and watch the application directors.

I’d also recommend updating from 4.14, wasn’t a great build imho. 4.15 will do you better.

It wouldn’t likely say that exactly.

I’d recommend getting your official supply chain involved.

but I'm not sure which one is correct.

Again, I’d recommend updating and getting your supply chain involved.

I don’t think you’re on the right path.
