Babel Buster Pro V230 BACnet to SNMP Gateway with Trap Receiver

Control Solutions’ Babel Buster® Pro-V230 is a an enhanced gateway with advanced features to support connecting BACnet IP and MS/TP to SNMP v1 and v2c. A variant of the Pro-V230 also includes support for connecting devices having a proprietary serial protocol to SNMP or BACnet IP.

The Pro-V230 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 Pro-V230 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. If more complex treatment of trap information is needed, Script Basic can be used to process traps and place resulting data into BACnet objects.

The Pro-V230 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 Pro-V230 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 Pro-V230 can send v1 or v2c traps based on threshold rules created via templates in the Pro-V230’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 Script Basic.

The Pro-V230 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 Pro-V230 can be BACnet IP and MS/TP client and server (concurrently). Maps created via templates in the Pro-V230’s web UI will read and write other BACnet devices, copying their data to local objects when read, or sending data from local objects to those devices when written.

The Pro-V230 includes template based rules for simple calculations and data tests. These can be used for simple data manipulation. If more complex formula based data treatment is needed, Script Basic has access to all local objects.

The Pro-V230-SP variant of the device repurposes the serial port to be used for a proprietary serial protocol instead of MS/TP. When used for interpreting a proprietary protocol, a Script Basic program would be written to send and receive via the serial port as applicable, and interact with the local BACnet objects (and MIB variables) under user program control.

The Pro-V230-SP allows you to BACnet enable or SNMP enable serial devices that otherwise have no network connection. Combined with rule templates, Script Basic can generate BACnet COV notifications or SNMP Traps.
