How to use Proface touch screen with Mitsubishi Q series PLC

In recent years, China's manufacturing industry has developed rapidly, and the degree of equipment automation is getting higher and higher. A series of tall nouns such as intelligent manufacturing and Industry 4.0 appeared before our eyes. In order to achieve this magnificent goal, every engineering technician is working hard.

The premise of achieving this magnificent goal needs to be supported by sufficient hardware. Today we will focus on the connection between plc and touch screen. People who have worked in factories have more or less seen touch screens. You can operate the device by clicking around on such a screen. It feels amazing. How does that work?

The touch screen HMI serves as a human-computer interaction interface. Control equipment actions by issuing equipment process parameters (temperature, frequency, speed, pressure, liquid level, etc.) and equipment commands, and feedback equipment operating status in real time to achieve communication between people and production lines. The following is an example of commonly used touch screen and plc;

At present, two communication methods are widely used. One is serial communication, the other is network communication

Another way is network communication, using standard IJ45 interface. That is, the data cable can be an ordinary network cable

HMI and PLC communication settings are so simple. As long as we think more and explore more in the course of our work, the troubles will be resolved soon.
