Babel Buster BB2-7010-01 (formerly IP/XM) 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.

The 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 IP/XM server for subsequent retrieval by any supported remote client (or master).

A large number of BACnet objects gives you flexibility in mapping Modbus registers to any combination of BACnet objects. Packed Modbus registers may be parsed to multiple BACnet objects when reading. Multiple BACnet objects may be packed into a single Modbus register when writing. All standard Modbus register types are supported.

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.
