Touch Screen and PLC Communication - Premier Cable

In practical control projects with PLC as the core, the vast majority of cases cannot do without the cooperation of touch screens or upper computers. Because we use PLC for control, the main task is to process some analog quantities, which are the values we need to monitor, such as pressure, temperature, flow rate, etc. on the equipment. Then, based on these detected values, we can control the electric valves, fans, water pumps, etc. on the equipment according to some conditions. But these values cannot be seen directly from the PLC. To see these values, you need to use a touch screen or industrial computer (which is actually a computer).

After we connect the touch screen to the PLC, we can see the data we want to see on the touch screen. In addition to data, various controlled objects on on-site devices can also be controlled through touch screens. For example, if we configure a switch on the touch screen, just click on this switch on the touch screen to start a motor on the on-site device.

Touch screens usually have a communication interface, which is used for communication with PLCs. The interface forms are mainly divided into three types: RS232, RS485, and Ethernet. It should be noted that the form of this interface must be the same as that of the PLC interface, which means that this interface is RS485. When connected to the PLC, the PLC interface must also be RS485.
