BACnet network integration with PRF/PRA

The only possible way to integrate PRF/PRA with BACnet network is by using a third-party BACnet device.

Requirement of BACnet network integration is verified on a case-by-case basis.

BACnet network requirements and considerations

Before integrating with a BACnet system, ensure the following requirements and considerations.

  • BACnet endpoints running on wireless gateways are only available to on-premise BACnet controllers and vice-versa.

  • BACnet traffic must be contained to a local network as the BACnet is an insecure protocol. BACnet traffic must not be routed through the internet.

  • Due to the insecure characteristics of the BACnet protocol, internet traffic or access to the internet on the BACnet VLAN is not recommended.

  • The BACnet VLAN must not be used to access the lighting network or the other way around.

Customer’s network responsibility

The following items must be shared with the customer:

The requirements are only applicable if the customer is delivering the network.

  • Lighting VLAN must comply with the PRF/PRA network and security requirements.

  • The correct network access controls (ACLs) must be in place to allow only authorized devices in the BMS and lighting VLAN.

  • BACnet controllers must be configured to communicate only by using the BACnet protocol in a lighting VLAN.

  • Network must be configured to block any non-BACnet communication from the BMS to the lighting VLAN and vice-versa.

  • Changes in the lighting VLAN require Signify approval.
