The SNMP version of the BB2-7010 is now available. This gateway uses SNMP Get requests to obtain data from SNMP devices commonly found in data center power equipment.

Note to IP/XM Users: The BB2-7010 is functionally identical, and your configuration files will work as is. Other than cosmetic enhancements, the changes are in hardware with additional indicators and a hardened EIA-485 port that will withstand accidental cross wiring between data and 24V power.

Babel Buster BB2-7010-01 (formerly Babel Buster IP/XM) contains three different clients and three different servers. The BB2-7010 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 BB2-7010 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 BB2-7010's BACnet IP client.
