过程控制

过程控制是指对温度、压力、流量等模拟量的闭环控制。作为工业控制计算机，PLC控制器能编制各种各样的控制算法程序，完成闭环控制。PID调节是一般闭环控制系统中用得较多的调节方法。大中型PLC都有PID模块，目前许多小型PLC控制器也具有此功能模块。PID处理一般是运行专用的PID子程序。过程控制在冶金、化工、热处理、锅炉控制等场合有非常广泛的应用。

数据处理

现代PLC控制有数学运算(含矩阵运算、函数运算、逻辑运算)、数据传送、数据转换、排序、查表、位操作等功能，可以完成数据的采集、分析及处理。这些数据可以与存储在存储器中的参考值比较，完成一定的控制操作，也可以利用通信功能传送到别的智能装置，或将它们打印制表。数据处理一般用于大型控制系统，如无人控制的柔性制造系统;也可用于过程控制系统，如造纸、冶金、食品工业中的一些大型控制系统。

通信及联网

PLC控制器通信含PLC控制器间的通信及PLC控制器与其它智能设备间的通信。随着计算机控制的发展，工厂自动化网络发展得很快，各PLC控制器厂商都十分重视PLC控制器的通信功能，纷纷推出各自的网络系统。新近生产的PLC控制器都具有通信接口，通信非常方便。

Process control

Process control refers to the closed-loop control of analog quantities such as temperature, pressure and flow. As an industrial control computer, PLC controller can compile a variety of control algorithm programs to complete closed-loop control. PID regulation is a common method used in closed-loop control system. Large and medium-sized PLC have PID module, many small PLC controllers also have this function module. PID processing is generally run a special PID subroutine. Process control is widely used in metallurgy, chemical industry, heat treatment, boiler control and so on.

Data processing

Modern PLC control has mathematical operations (including matrix operations, function operations, logic operations), data transmission, data conversion, sorting, table lookup, bit operation and other functions, can complete the data collection, analysis and processing. These data can be compared with the reference values stored in the memory to complete certain control operations, and can also be transmitted to other intelligent devices by means of communication functions, or they can be printed and tabulated. Data processing is generally used in large control systems, such as unmanned flexible manufacturing systems; It can also be used in process control systems, such as some large control systems in the paper, metallurgy, and food industries.

Communication and networking

PLC controller communication includes the communication between PLC controllers and the communication between PLC controllers and other intelligent devices. With the development of computer control, the factory automation network has developed rapidly, and the PLC controller manufacturers attach great importance to the communication function of the PLC controller, and have launched their own network systems. Recently produced PLC controller has communication interface, communication is very convenient.
