Babel Buster SP is a Modbus to Modbus and a Modbus to SNMP Gateway. Babel Buster SP is more than a protocol translator. It is a self contained server that collects and distributes data according to the rules you create. The most common use of the SP is to map Modbus RTU and/or Modbus TCP devices to SNMP. The SNMP manager can use SNMP Get to retrieve contents of any mapped Modbus register. In addition, the Babel Buster SP uses threshold rule templates to continuously monitor Modbus data and generate SNMP Traps upon sensing of "alarm" conditions. Babel Buster SP is an SNMP agent (does not include SNMP manager).

The primary applications for Babel Buster SP are serial to Ethernet conversion for Modbus devices, and SNMP access to serial or Ethernet Modbus devices. As a Modbus to Modbus gateway, Babel Buster SP will map multiple RTU devices to a single Modbus TCP server map. It can also map multiple Modbus TCP devices to a single RTU slave map. The SP can also do Modbus TCP to Modbus TCP register re-mapping to retrofit equipment to a legacy Modbus register map. The Modbus RTU port can be configured as master or slave. The Modbus TCP port can operate as both client and server (master and slave) concurrently.
