Internal communication

Important: Set up all virtual servers on the same VLAN subnet as the plant automation system to avoid the need for routing rules and tables between subnets.

Plant Optimizer uses industry-standard protocols to connect to the NAE, such as HTTP, HTTPS, and BACnet®. The NAE uses MODBUS, LON, and BACnet to connect to the plant automation system.

Note: If the NAE is on a different subnet to the Plant Optimizer server, open port 47808 on Plant Optimizer for NAE BACnet/IP Broadcast Management Device (BBMD) communication traffic. If the NAE is on the same network subnet as the Plant Optimizer server, the BACnet communication does not require a BBMD.

Johnson Controls works with your plant automation system maintenance services provider to set up the network connections.

External communication

The Plant Optimizer server connects to the Internet using HTTP or HTTPS to access data from external web services, such as weather forecast data or utility prices. Configure the site firewall or proxy server to allow the outgoing connection from the CUP server.
  • For a HTTP connection, access firewall port 80.
  • For a HTTPS connection, access firewall port 443.
