Application field of A-B 81001-340-71-R high-voltage frequency converter module; At present, PLC controllers have been widely used in various industries such as steel, petroleum, chemical, electricity, building materials, mechanical manufacturing, automobiles, light textiles, transportation, environmental protection, and culture. The usage situation can be roughly summarized into the following categories. Logic control of switching value; This is the most basic and widespread application field of PLC controllers, replacing traditional relay circuits to achieve logic control and sequential control. It can be used for control of a single device, as well as for multi machine group control and automation lines. Such as injection molding machines, printing machines, bookbinding machines, modular machine tools, grinders, packaging production lines, electroplating lines, etc. Analog quantity control: In industrial production processes, there are many continuously changing quantities, such as temperature, pressure, flow rate, liquid level, and speed, which are all analog quantities. In order for programmable controllers to process analog signals, it is necessary to achieve A/D conversion and D/A conversion between analog and digital signals. PLC manufacturers all produce matching A/D and D/A conversion modules to use programmable controllers for analog control. Motion control: PLC controllers can be used for controlling circular or linear motion. From the perspective of control mechanism configuration, in the early days, it was directly used to connect position sensors and actuators with switch/O modules. Nowadays, specialized motion control modules are generally used. A single axis or multi axis position control module that can drive stepper motors or servo motors.

Process control: Process control refers to closed-loop control of analog quantities such as temperature, pressure, and flow. The A-B 81001-340-71-R high-voltage frequency converter module serves as an industrial control computer, and the PLC controller can program various control algorithms to complete closed-loop control. PID regulation is a commonly used regulation method in general closed-loop control systems. Large and medium-sized PLCs all have PID modules, and currently many small PLC controllers also have this functional module. PID processing generally involves running specialized PID subroutines. Process control is widely used in metallurgy, chemical engineering, heat treatment, boiler control, and other fields. Data processing: Modern PLC control has functions such as mathematical operations (including matrix operations, function operations, and logical operations), data transmission, data conversion, sorting, table lookup, and bit operations, which can complete data collection, analysis, and processing. The A-B 81001-340-71-R high-voltage frequency converter module can compare these data with reference values stored in memory, complete certain control operations, or transmit them to other intelligent devices through communication functions, or print them for tabulation. 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-scale control systems in papermaking, metallurgy, and food industries. Communication and networking PLC controller communication includes communication between PLC controllers and communication between PLC controllers and other intelligent devices.
