Process control refers to the closed-loop control of temperature, pressure, flow and other analog quantities. As an industrial control computer, PLC can program various control algorithms to complete closed-loop control. PID regulation is a widely used regulation method in general closed-loop control system. Large and medium-sized PLCs have PID modules, and many small PLCs also have this function module at present. PID processing is generally to run special PID subroutines. Process control is widely used in metallurgy, chemical industry, heat treatment, boiler control and other fields.

data processing

Modern PLC has the functions of mathematical operation (including matrix operation, function operation and logic operation), data transmission, data conversion, sorting, table lookup, bit operation, etc., which can complete 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 using the communication function, or they can be printed and tabulated. Data processing is generally used in large-scale control systems, such as unmanned flexible manufacturing systems; It can also be used in process control systems, such as some large control systems in paper making, metallurgy and food industry.

Communication and networking

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