Use the BACnet Router feature to add all the controllers under the control of a SBH, into a larger supervisory system via BACnet/IP integration. You can use this feature in a number of situations. For example:
- A new addition
- A segregated wing of a building
- A remote building that you want to tie into an existing Building Automation System (BAS).
The SBH has a list of devices on the system bus that are connected by RS-485 and an active BACnet/MSTP. When the BAS sends out the Who-Is message, the SBH responds for itself and all devices under its control. Optionally, you can set up a BACnet IP Broadcast Management Device (BBMD) if the SBH and BAS are on different subnets.
To configure the BACnet router feature, complete the following steps:
- Navigate to the Settings tab.
- Under the Settings tab, select the BACnet Settings
option and adjust the following parameters:
- Device Object Identifier – Identifies the SBH as a unique device on a BACnet network. Adjustable: 0 to 4194303, default 1.
- MAC Address – Sets the address on the system bus for the MS/TP network. Adjustable: 4 to 127, default 117.
- Network Number – Sets the routing address for devices under the SBH. Adjustable: 1 to 65534, default 64999. It is best practice to leave the network number on the default setting.
- Routing Mode – In this mode, the SBH can utilize the routing feature which identifies MS/TP devices over the IP integration.
- UDP Port – Defines the port for the UDP traffic. By default, BACnet uses 47808 but the use of other ports are optional. Adjustable: 47808 to 47823.
