More than just a protocol converter.


Port Forwarding Protocol Converter


CommTRAX is a compact protocol converter that acts as a server, collecting data from various MODBUS RTU devices and distributing it at a low Bandwidth within a single register package.

The Modbus TCP port can operate as both client and server (master and slave). In addition, CommTRAX can use threshold rule templates to continuously monitor modbus data and generate SNMP Traps upon sensing “alarm” conditions. As a Modbus to Modbus gateway, CommTRAX can map multiple RTU devices to a single Modbus TCP server map.

The COMMTRAX is an All-in-One remote monitoring solution

Designed to provide employees and management with the information they need to make better decisions more quickly. Using only one device with built-in automation features, Network Maintenance Staff, Network Operating Centres, and Safety and Energy Committees can pull historical and real-time data from any type of critical infrastructure to remotely control and optimize operations.

COMMTRAX integrates with existing fault management process and management software.
  • Works with an intuitive Web-based interface to see site conditions anywhere, at any time on your smartphone, tablet or computer
  • Measures, calculates and provides real-time Key Performance Indicators such as AC Mains, UPS, Generator and HVAC utilization levels, Rectifier, UPS, Inverter efficiency levels and site Facility Power Usage Effectiveness as well as Data Center Infrastructure Efficiency (DCIE)
  • LiveScript allows the use of mathematical equations and logic
  • Smart alarm messages are transmitted via email, SNMP traps, text messages, and more
  • Compatible with Management Software, Automation software, PLCs and applications supporting SNMP communication



Eliminates the need for PLCs, multiple RTUs, and monitoring and metering devices
