Modbus has been connecting industrial devices for more than four decades, yet many engineers use it every day without knowing how much work it does behind the scenes.

It is not a sensor or a controller. It is the communication language that allows PLCs, SCADA systems, flow meters, drives, power meters, valve controllers, and other field devices to exchange data reliably.
Whether you are reading a pressure transmitter, starting a motor, monitoring energy consumption, or controlling a valve, there is a good chance Modbus is carrying that information.
Simple. Reliable. Proven.
Sometimes, the most important technology in a plant is the one nobody notices until communication is lost.
What's the most devices you've ever connected on a Modbus network?
