Go modbus stack (client and server)

Go modbus server

This repo is a simplified version of github.com/simonvetter/modbus

The main changes are:

• simplified the modbus server
• removed TLS handling (this should be done in the calling application)
• added an Option interface to creating the server
• added a DummyHandler
• removed modbus client (use github.com/grid-x/modbus)

Description

This package is a go implementation of the modbus protocol. It aims to provide a simple-to-use, high-level API to interact with modbus devices using native Go types.

Please note that UDP transports are not part of the Modbus specification. Some devices expect MBAP (modbus TCP) framing in UDP packets while others use RTU frames instead. The client support both so if unsure, try with both udp:// and rtuoverudp:// schemes.

The server supports:

• modbus TCP (a.k.a. MBAP)
