Functions of PLC

With the rapid development of automation technology, computer technology and network communication technology, the functions of PLC are increasing. It can realize not only single machine control, but also multi machine group control; It can not only realize logic control, but also realize process control, motion control and data processing. Its main functions are as follows:

1. Switching logic control

This is the most basic function of PLC. PLC has powerful logic operation ability. It provides various logic instructions such as and, or, and can realize the switch control of various connections such as series, parallel and series parallel of relay contacts. It is often used to replace the traditional relay control system. The timing and counting functions can be realized by using the timing and counting instructions provided by PLC. The timing value and counting value can be set by the user during programming or by using the digital dial switch. The value can be modified online, and the operation is very flexible and convenient.

2. Analog control

In the process of industrial production, there are many continuously changing quantities, such as temperature, pressure, flow, liquid level and speed, which are analog quantities. PLC provides various intelligent modules, such as analog input module, analog output module, analog input and output module, analog input module for thermal resistance, analog output module for thermal resistance, etc. through the use of these modules, the analog input on site is sent to CPU for processing after a/d conversion; The digital result processed by CPU is converted into analog quantity by d/a to control the controlled equipment, so as to complete the control of continuous quantity.

3. Closed loop process control

Using PLC can not only carry out open-loop control on analog quantity, but also carry out closed-loop control. Configure PID control unit or module to carry out PID control on a variable (such as speed, temperature, current, voltage, etc.) in the control process.
