Gone are the times once centralized industrial systems used Brobdingnagian cupboards with instrumentation connecting by kilometers of thick cables to sensors and actuators. Today, within the overwhelming majority of cases, it's rather more profitable to put in many native controllers, united in a very single network and causing information to the servers via economical communication protocols like Modbus. this permits saving on installation, testing, and maintenance of business instrumentation compared to centralized systems.

In this article, we’ll tell you why Modbus communication protocol is that the high selection for industrial networks and that advanced COM port program computer code can facilitate your scan Modbus messages within the simplest and most convenient means.
