Serial Server Modbus
Project Image
The project consisted of updating the existing firmware for Serial Server Devices through adding new partial functionality to a Modbus protocol.
The project included design and development of a Modbus gateway with a pass-through Ethernet port. The gateway supports the Modbus TCP server and Modbus RTU serial with Modbus slave devices attached to the serial ports. The gateway allows customers to replace the three box solution with a single box solution. Along with new protocol implementation, the internal web server was updated as well as the desktop utility for remote device configuration and firmware update. The created desktop automated testing utility was developed for testing the solution.
