Modbus Support for Serial Server
Project Image The main objective of the Modbus Support for Serial Server project was to update existing firmware for Serial Server device by adding Modbus protocol support. The project included design and development of a Modbus gateway with a pass-through Ethernet port. The gateway was made to support the Modbus TCP server and Modbus RTU serial with Modbus slave devices attached to the serial ports. The gateway allows the customer to replace the three box solution with a single box solution. Along with new protocol implementation, updates were made to internal web server as well as the desktop utility for remote device configuration and firmware update. Additionally PSA has implemented automated testing utility to verify the solution.
