Upgrade from
Babel Buster 485XM
We highly recommend moving up to the BB2-3010 if you have been using the BB-485XM. Even if you do not need the added capacity, you are likely to benefit from the hardened RS485 ports. Your existing XML configuration files for the 485XM will import directly into the BB2-3010 configuration tool.

Control Solutions’ Babel Buster® BB2-3010 is a BACnet MS/TP client/server device that functions as a Modbus RTU master/slave. 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.

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 BB2-3010 supports up to 300 non-commandable objects, or up to 135 commandable objects, or a mix in between.

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 to the Modbus Holding register.

The BB2-3010 is most often used as a Modbus master, but it can operate as a slave while MS/TP operates as a client (master). This makes it possible to put MS/TP devices on a Modbus network (but does still require an understanding of BACnet). MS/TP data in remote devices is queried and saved locally. The local data may then be accessed by another Modbus master.

MTX002 USB to MS/TP Adapter

We have an exciting new utility tool to go with our exciting new gateway. We got tired of fighting with dongles and adapters and systems that did not work nearly as well as we would like. So we fixed it. This intelligent adapter plugs into your PC's USB port, and offloads the MS/TP token passing from the PC to make it reliable. It operates as an MS/TP device on the network by default. It can also be put into pass-through mode to create a simple RS485 adapter for testing Modbus RTU devices.

How do you map a Modbus register to a BACnet object?

It is as simple as entering a register number, selecting the register type, and telling the gateway what the Modbus device's network address is.

 Using the free configuration tool provided by Control Solutions (download from this web site), you simply need to select register type and format from drop-down lists, fill in register number, choose a slave ID and poll rate, check the Enable Map box, and click the Write button to send this to the Babel Buster.

It is not a requirement that you use the Control Solutions configuration tool to configure the Babel Buster gateway. Any BACnet client capable of writing both standard and manufacturer specific object properties (using only standard BACnet data types) can configure the gateway.
