Control Solutions' Babel Buster® BB2-3060 is a fully configurable universal Modbus TCP to BACnet MS/TP gateway. The Babel Buster BB2-3060 is a TCP client (master) used to make multiple Modbus TCP devices accessible on a BACnet network. The BB2-3060 is also capable of acting as a BACnet MS/TP client and Modbus TCP server (slave), allowing BACnet devices to be connected to a Modbus network.

Control Solutions’ Babel Buster® BB2-3060 is a BACnet MS/TP client/server device that functions as a Modbus TCP client/server. 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 BB2-3060 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 BB2-3060 is most often used as a Modbus TCP client (master), but it can operate as a Modbus TCP server (slave) while MS/TP operates as a client (master). This makes it possible to put MS/TP devices on a Modbus TCP 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.
The BB2-3060 configuration tool connects to the MS/TP network using the MTX002 MS/TP to USB adapter (if not using a BACnet IP router). This intelligent adapter plugs into your PC's USB port, and offloads the MS/TP token passing from the PC to make it more reliable. The MTX002 allows you to connect your PC to an MS/TP network running at 76800 baud, something not possible with a generic RS485 port adapter.
The MTX002 functions as an MS/TP device itself. The combination of the MTX002 and configuration tool running on your PC will appear on the network as a discoverable BACnet device. The diagnostic pages in the configuration tool can be used to read and write any objects in any MS/TP device on the network. The configuration pages provide templates for reading and writing the multiple properties per BACnet object that define its Modbus mapping. All configuration parameters exist as properties of BACnet objects which are accessible to any BACnet client. The Control Solutions configuration tool simpy provides a user friendly template for accessing those properties.
The BACnet Gateway Configuration Tool is the most user friendly BACnet gateway configuration tool to date. Connect the gateway to your laptop via a USB to MS/TP adapter (MTX002) or via a BACnet IP router.
Import Modbus register lists formatted as CSV files. Create your register list using any standard spreadsheet program, save as CSV, then import. The tool will then automatically create and assign BACnet objects. You can also start with a BACnet object list, saved as a CSV file, and import the object list. The tool will automatically assign Modbus registers. Or you can specify the complete mapping of BACnet objects to Modbus registers in a CSV file and import that.
You do not need to start with a CSV list. The user friendly tool provides templates to build a complete configuration from scratch. The configuration tool also provides the means to allocate the gateway's object pool to Analog, Binary, or Multi-state type objects, as Inputs, commandable Outputs, or Value objects.
Models BB2-3060 and BB2-7030 can both be used as an MS/TP to Modbus TCP gateway. Which one should you use?
If you are familiar with the BB2-3010 Modbus RTU to BACnet MS/TP gateway, and would like to use a Modbus TCP version of the same gateway using the same configuration tool, then the BB2-3060 is the better choice. Some will find the Windows based configuration tool for the BB2-3060 to be more convenient than the web based configuration of the BB2-7030.
If you are already familiar with the BB2-7010 or BB2-7030, then the BB2-7030 will have a familiar look and feel. However, because the BB2-7030 is also a BACnet router, it will potentially cause problems if you do not disable routing when there are other routers on the network and you only want to use the BB2-7030 as a gateway. If you prefer web based configuration, then the BB2-7030 is a good choice for you.

Babel Buster Configuration Builder
The Configuration Builder software available for use with the web based gateways (such as BB2-7010) is not needed for the BB2-3010 or BB2-3060 because CSV import capability is already included in the configuration tool for the BB2-30x0 gateways.
The CSV import simplifies the process of creating or changing a large number of entries because you can use any standard spread sheet program to manipulate the content of one or more CSV files, and then import that configuration to be loaded into the gateway. If the gateway will be reading a long list of Modbus registers, for example, you can sometimes just copy a list of registers from another source, paste into a simple text file, and import that into the spread sheet program. Then add a header line to label the content, add a handful of additional columns, and you quickly have most of a complete configuration. Very often, the only thing that changes from one line to the next is the register number. The other entries can be quickly made by entering once and using the spread sheet program's "fill down".

Need even more help with your network gateway configuration task? We can do the configuration for you, or at least give you a big head start. We are working on building a library of configuration files for commonly used devices. If yours isn't already in the library, we will add it. To get started, open a support ticket and attach a copy (typically a .pdf document) of whatever documentation you have for your device. In addition, provide a list of the registers or objects you want to read or write. Of course, you can also start by asking if we already have that device in our library. If you have a proprietary application that you do not want included in our library, you can hire us at a very reasonable rate to do custom, proprietary configuration work for you, too.
Our most extensive technical support is provided by the same engineering staff that developed the products. Your personal attention from this staff is available via the support ticket system.
