Communicating with BACnet

The BACNET driver is designed to communicate with BACnet networks and devices using the BACnet/IP transport option. The following diagram illustrates how Plant SCADA communicates to different types of BACnet networks.

The diagram illustrates the following:

• Each network is uniquely identified by a number.

• Each device has an address uniquely identifying it on a network.

• Each device has a unique device ID in the whole BACnet network.

• The device ID is used to uniquely identify each device in Plant SCADA.

• Each BACnet device corresponds to an I/O Device in Plant SCADA.

• Plant SCADA communicates to non-BACnet/IP networks via BACnet routers.

• Plant SCADA I/O device redundancy is provided.

  

Note: The BACNET driver only needs one port configured in Plant SCADA. This is because the driver will only initialize one instance of Cimetrics BACstac which it will use to communicate with all devices. Therefore, you only need to configure one board and one port in your Plant SCADA project.
