Control Solutions’ Babel Buster BB3-6101-V3 is a Modbus to SNMP Gateway used to connect Modbus RTU or Modbus TCP devices to your SNMP network. The SNMP manager can use SNMP Get to retrieve contents of any mapped Modbus register. In addition, the BB3-6101 uses threshold rule templates to continuously monitor Modbus data and generate SNMP Traps upon sensing of “alarm” conditions.

The BB3-6101-V3 supports SNMPv3 as well as SNMPv2 and SNMPv1. User credentials for SNMPv3 access are entered via the built-in secure web user interface.

The BB3-6101-V3 will automatically poll whatever Modbus devices and registers you tell it to, and hold a copy of the data for access by SNMP. You can provide SNMP access to Modbus coils, discrete inputs, input registers or holding registers. The BB3-6101-V3 supports 16, 32, and 64 bit integer data, 32 and 64 bit floating point, and character strings as a series of Modbus registers. The Modbus registers you want to make accessible to SNMP are configured with “read maps” in the BB3-6101.

You can also write to Modbus using SNMP Set. Simply configure a “write map” in the BB3-6101 to make this connection. SNMP can send data to Modbus coils or holding registers in the remote Modbus device.

The BB3-6101-V3 can be Modbus RTU master or slave, and can be Modbus TCP client and server concurrently. The BB3-6101’s Modbus register map is user configurable.

Control Solutions has benchmark tested a configuration in which the BB3-6101 MIB size was 1,500 variables and external SNMP manager tools could successfully walk the entire MIB in a very short time. Your MIB size may vary depending on how resources are allocated in your particular application. The resource allocation page allows you to tell the BB3-6101 how many of each type resource you want. It then calculates usage and indicates utilization as a percentage of resources available. As long as your total utilization remains at 100% or less, you can reconfigure the resources any way you like.

The MIB is divided into branches, with the 32-bit integer branch being the most universal. There are also 64-bit integer, and both 32-bit and 64-bit floating point branches as well as a character string branch. You configure the MIB by assigning local Modbus registers to positions in the MIB branch.

Traps (or SNMPv3 Notifications) are generated based on rule templates you fill in, and they reference data found in the MIB branches. In addition to sending the relevant data with the trap or notification message, the templates include user defined character string messages.

The BB3-6101-V3 is a significant enhancement over its predecessor, the BB2-6010. The hardware includes a faster processor and hardware encryption engine for efficient rendering of secure web pages and for support of encryption as needed for SNMPv3. The software includes numerous enhancements.

• SNMPv3 support (in addition to SNMPv1/v2)
• IPv6 support
• Secure (HTTPS) web server
• Higher point count, up to 1,000 MIB variables typical
• User defined register map for Modbus
• Greater flexibility in assigning local register data types
• Support for reading character strings from Modbus
• CSV import of register maps for client/master configuration
• Menu options to clear part or all of configuration

Configuration of the BB3-6101-V3 gateway is done via the web pages served by the internal web server. You simply fill in templates. The entire configuration is saved in the internal Flash file system in XML format. This file may be exported to replicate additional copies of the configured device, or for backup.

The BB3-6101-V3 includes template based rules for simple calculations and data tests. These can be used for simple data manipulation. Reformatting from one register type to another is automatic. Therefore, a simple copy rule will transform a number into an ASCII string for use in sending traps.

 Configuration Builder

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.
