White Paper: Introduction to Modbus

Close the technology gap with this introduction to Modbus. Learn how to use legacy code to solve your modern challenges.

Feb 17th, 2009

Modbus is one of the most popular protocols used in the industrial world. Supporting traditional serial protocols of RS232/422/485 and Ethernet protocols allow industrial devices such a PLCs, HMIs and meters to use Modbus as their communication method. When communicating with Modbus via serial and Ethernet networks, a communication gateway is a necessity.
