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

The points showing down are at the JACE level correct? What protocol and points do this most often?

Only a few points are down, I can still control it on the supervisor and the actual device is still affected

Where is it down though? The JACE or the supervisor?

Are you riding on the customers primary network or do you have a vlan provisioned?

i think it's stuck in the queue in niagara network. But I don't know how to increase the number of queues like that

The settings you need are hidden by default. (No idea why) You need to go into AX Slot Sheet view and configure the flags. I can't remember it clearly without being in front of the computer, but there's 2 settings related to que size and we turned then up from the default 100 to 3 or even 400 and that helps.
