Babel Buster BB2-7010 BACnet IP to Modbus Gateway provides a BACnet IP client and server, Modbus TCP client and server, and Modbus RTU port configurable to be master or slave. The BB2-7010 BACnet IP client allows BACnet IP devices to be accessible from Modbus TCP or RTU. You configure the device instance, object type and instance, and poll interval for reading or writing BACnet objects. The object data is stored in the BB2-7010 server for subsequent retrieval as Modbus registers. When used to connect Modbus devices to a BACnet IP network, the BB2-7010 is configured via simple web page templates to read and write Modbus registers in one or more Modbus slaves, making that data accessible as BACnet objects on the BACnet IP network.
