ABB 3DDE300403CMA123 Reliable Operation Main application fields of PLC 1. Switching value logic control Replacing the traditional relay circuit to realize logic control and sequence control, it can be used not only for the control of single equipment, but also for multi machine group control and automatic assembly line. Such as injection molding machine, printing machine, stapling machine, modular machine tool, grinder, packaging production line, electroplating assembly line, etc. ABB 3DDE300403CMA123 Reliable Operation 2. Industrial process control In the process of industrial production, there are some continuously changing quantities (i.e. analog quantities) such as temperature, pressure, flow, liquid level and speed. PLC uses corresponding a / D and D / a conversion modules and various control algorithm programs to process analog quantities and complete closed-loop control. PID regulation is a regulation method used more in general closed-loop control system. Process control is widely used in metallurgy, chemical industry, heat treatment, boiler control and so on. ABB 3DDE300403CMA123 Reliable Operation 3. Motion control PLC can be used to control circular motion or linear motion. Generally, special motion control modules are used, such as single axis or multi axis position control modules that can drive stepping motors or servo motors. They are widely used in various machinery, machine tools, robots, elevators and other occasions. 4. Data processing 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., and can complete data acquisition, analysis and processing. Data processing is generally used in some large-scale control systems such as papermaking, metallurgy and food industry. 5. Communication and networking PLC communication includes communication between PLC and communication between PLC and other intelligent equipment. With the development of factory automation network, PLC now has communication interface, which is very convenient
