GoModbus

A TCP Modbus client in Go

This is an expermintal TCP Modbus client written in Go for testing and protyping purposes. The code is in an alpha state, still needs some work and is provided as-is. Please keep my name in the files as the author if reused.

What is Modbus? Modbus is a popular industrial device protocol used to communicate with numerous devices worldwide. A good primer on the protocol can be found at: http://www.simplymodbus.ca/FAQ.htm#Modbus

Code structure:

  1. ModbusClient folder is where the main package is, the entry point for the project
  2. GoModbusTCP folder is where the Modbus TCP implementation resides. There is a file for each Modbus device type and a file that acts as a factory of device structs based on the user requests. This could evolve to become an API in the future

Notes:

  1. CRC not supported
  2. If enough people find that interesting, I would like to evolve this to be a Go Modbus API
  3. Code can be tested with Modbus simulators
  4. I may write a tutorial in the future covering the design details when I get a chance.
