Connecting to BACnet

To connect a BACnet client to the PDDEG-S, you must configure the PDDEG-S Ports editor and BACnet editor > General (Advanced) properties. The BACnet consultant can then enter this information into their BACnet client software.

You must first configure the PDDEG-S with the sb icon bridge wizard Bridge Configuration Wizard and ensure that you select the sb icon checkbox tick Enable Websocket / Cloud Connection / BACnet checkbox in Step 2 (BACnet uses the WebSocket connection). The wizard does not modify Port 2 settings.

Ethernet Port 1 can be configured to connect to the lighting control system or to BACnet.
Ethernet Port 2 can only be configured to connect to BACnet and only supports a static IP address.

To see all relevant properties, ensure that sb icon advanced  Advanced view is enabled.

  • We recommend connecting the BMS and lighting systems on different networks or VLANs. System Builder does not allow Port 1 and Port 2 to be configured on the same subnet. If you attempt to assign an IP address to Port 2 that falls within the same subnet as Port 1, the configuration will be rejected.

  • System Builder v4.46 or later and PDDEG-S firmware 2v18b or later is required to enable Ethernet Port 2 functionality. Do not downgrade the firmware once Port 2 is enabled.
Please provide the following information to the BACnet consultant:

  • Ports editor
