The Babel Buster MX-73-V2C BACnet Router routes BACnet messages between BACnet IP and BACnet MS/TP networks. The MX-73-V2C BACnet Router can be a learning router or configured router, and includes BBMD support. The MX-73-V2C BACnet Router also provides slave proxy capability to answer to Who-Is messages on behalf of devices that do not support dynamic binding.

Babel Buster MX-73-V2C BACnet Router can also operate as a BACnet to SNMP gateway. The MX-73-V2C provides an SNMP client and server in addition to the BACnet client and server. The MX-73-V2C can be used to connect SNMP devices to a BACnet network.

The Babel Buster MX-73-V2C contains a user defined set of BACnet objects. Those objects are mapped to the gateway’s MIB, each with a unique OID. The gateway’s BACnet client can query other BACnet devices and store those values in the gateway’s local objects. The gateway’s SNMP client can query other SNMP devices and also store those values in the gateway’s local objects. Both clients can also write to other BACnet or SNMP devices. The objects or variables that are to be read or written in other devices are easily configured by the user. At the same time, other BACnet devices can query the local BACnet objects in the gateway, and other SNMP devices can Get/Set objects via the MIB.

BB3-7302 BACnet Router plus SNMP Gateway Functionality

The Babel Buster MX-73-V2C also includes an automatic table walker and flexible trap receiver that fully supports connecting BACnet to a UPS that implements the RFC 1628 MIB for UPS systems.

The MX-73-V2C is an upgrade alternate for BB2-7030-02 offering higher performance at a lower cost. Routing efficiency is improved and gateway capacity increased. The MX-73-V2C also provides a secure (https) web user interface.

Control Solutions’ Babel Buster MX-73-V2C is a an enhanced BACnet router and gateway with advanced features to support connecting BACnet IP and MS/TP to SNMP v1 and v2c.

The MX-73-V2C as a BACnet Router will route IP to MS/TP and vice versa via its local ports, and supports full router capability for multi-hop internetworks including via NAT WAN routers. Routing is simple to set up. Routing can be used without any other gateway features enabled. Routing can be configured or automatically learned.

The MX-73-V2C as a BACnet Client/Server Gateway will poll BACnet IP and/or BACnet MS/TP slaves or servers, and retain copies of selected object properties. Upstream clients may then query the MX-73-V2C to receive data originating from multiple devices.

The MX-73-V2C includes an SNMP client that can read and write MIB variables in other SNMP devices. When reading, the remote device’s data will be stored in a local object. When writing, data  will be taken from a local object and sent to the remote SNMP device via SNMP Set.

The MX-73-V2C includes an automatic table walker with multiple algorithms making it suitable for walking the sparse alarm table found in UPS systems implementing RFC 1628. The table walker can easily translate the alarm table into a series of BACnet objects for easy access by a BMS.

The MX-73-V2C includes a trap receiver supporting both v1 and v2c traps. The template driven trap receiver provides multiple algorithms for recognizing traps, and can easily place trap information into BACnet objects.

The MX-73-V2C is itself an SNMP device. Local BACnet objects can be assigned to either of the branches of the local MIB for remote access by other SNMP clients. The local data may be accessed as scaled integer or 32-bit floating point (RFC 6340). An SNMP Get to the MX-73-V2C will read local objects and an SNMP Set will write the local objects. If local objects are mapped via BACnet to write to other BACnet devices, then SNMP Set will result in writing to a BACnet device.

The MX-73-V2C can send v1 or v2c traps based on threshold rules created via templates in the MX-73-V2C’s web UI. When data in the local objects meets the rule criteria, the trap will be sent. Traps can be triggered by reading other BACnet devices or by any other source of local data including the SNMP client.

Babel Buster MX-73-V2C is UPS Friendly

The alarm table in a typical UPS system cannot be directly polled due to the fact that alarm table entries are only present while alarms are present, and attempts to poll the alarm data with no alarms present will result in errors. The table walker in the MX-73-V2C has the intelligence to scan the alarm table for alarms, and set BACnet Binary objects to Active when alarms are found, and automatically clear Binary objects to Inactive after a timeout when not found.

In addition to walking the alarm table of a UPS, the trap receiver in the MX-73-V2C can effectively translate SNMP Traps into BACnet COV notifications. The combination of trap receiver and BACnet client also means SNMP Traps can result in writing status information to objects in other BACnet devices

The BB3-73-V2C includes its own internal web server that provides a web based user interface for configuring the MX-73-V2C. Configuration is done using simple templates, and each web page has an online help section at the bottom.

CSV to XML Conversion Tool

Babel Buster Configuration Builder

You would normally use the web pages found in the gateway itself to configure the gateway. But you may be able to take a shortcut if you have a long list of registers already in CSV file format.

The Babel Buster Configuration Builder is used to facilitate building of configuration files (aka "profiles") for Babel Buster network gateways by converting XML files to CSV files and vice versa. This 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 convert that into an XML configuration file that can 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".

The Babel Buster Configuration Builder simplifies the process of making global changes to a large number of gateway register or object "maps". The gateway “converts” protocols by querying devices on one network with one protocol, and then saving that data internally so that it may be accessed on another network using a different protocol. The designation of what should be queried is referred to as a “map” in the gateway. In most applications, most or all maps are “read” maps, meaning the gateway will read data from some other device. A “write” map will write data to that device. Most often the gateway will actively read data from a device and passively wait for another device on the alternate network to query the gateway to obtain that data. But it is also possible to configure the gateway with two sets of maps, one to actively read device A using protocol A, and then actively write that data to device B using protocol B. The process can also be reversed, and can be done concurrently. You may both read and write data on one network while writing and reading data on the other network.

What to Expect from the Conversion Tool

The point of this configuration builder is to simplify the process of entering long lists of registers or objects. Where most of the parameters are the same for many maps, using a spread sheet program's "fill down" makes the process fast and easy.

There are situations where creating a CSV file for configuring some aspect of the gateway is actually going to create more work than simply using the web UI or PC based software to directly configure that aspect. Configuring the Modbus RTU port baud rate is one such example. There is only one setting. A CSV file would create more work rather than less, as intended. Therefore, the configuration builder only supports CSV import/export for those aspects of gateway configuration that involve long lists of largely replicated parameters. There are a very limited number of list type entries that are not supported in part because they are seldom used, and in part because very little of the list is replicated from one entry to the next. The BACnet Broadcast Distribution Table is one such example.

Do note, however, that if you have already done a lot of configuration, have saved that to an XML file, and want to add a list from a CSV file, you can do that. Refer to the section in the user guide that talks about modifying an existing configuration.

Configuration Service

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.

No user/password is required to open a new ticket. Once you open a ticket, you will immediately receive an email with your ticket number. Your ticket number becomes your login to review your ticket(s) later. Click the Support Ticket icon anywhere you see it.
