UPDATE: We now have a newer gateway that has higher performance and higher capacity than the BB2-7010-01 and for the same price. Take a look at BB3-7101.
Babel Buster BB2-7010-01 contains three different clients and three different servers. The 7010 includes BACnet/IP client and server, Modbus TCP client and server (master and slave), and Modbus RTU master and slave.
Value objects will poll their assigned Modbus register at the interval you specify. The content of the Modbus register will be given as the Present Value of the BACnet object when read. The Modbus register is written each time the BACnet Value object is written. The Value object corresponds well with the Modbus Holding register.
Input objects will poll their assigned Modbus register at the interval you specify, and provide the Modbus data as the Present Value when read. Commandable Output objects are used to write Modbus registers, and will update the Modbus device each time BACnet is updated.
The same polling schemes that apply to Modbus also apply to remote BACnet IP slaves polled by the 7010's BACnet IP client, and apply to SNMP or WiFi sensor polling as applicable.
