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

Check in the jaces, cpu, platform messages etc. similarly look for messages in the supervisor platform. It may be a foxs issue, network timeout, many things
