Arithmetic function
The operation function of simple programmable logic controller includes logic operation, timing and counting function; The arithmetic function of ordinary programmable logic controller also includes the arithmetic function of data shift and comparison. More complex operation functions include algebraic operation, data transfer, etc. The large programmable logic controller also has analog PID operation and other advanced operation functions. With the emergence of open systems, programmable logic controllers have communication functions, some products have communication with the next machine, some products have communication with the peer machine or host computer, and some products also have the function of data communication with the factory or enterprise network. Design and selection should be based on the requirements of practical applications, reasonable selection of the required computing functions. Most applications only need logical operations and timing and counting functions, some applications need data transfer and comparison, when used for analog detection and control, only use algebraic operations, numerical conversion and PID operations. Operations such as decoding and encoding are required to display the data. Control function
The control function includes PID control operation, feedforward compensation control operation, ratio control operation, etc., which should be determined according to the control requirements. Programmable logic controller is mainly used for sequential logic control, therefore, most occasions often use a single loop or multi-loop controller to solve the analog control, and sometimes also use a dedicated intelligent input and output unit to complete the required control functions, improve the processing speed of programmable logic controller and save memory capacity. For example, PID control unit, high-speed counter, analog unit with speed compensation, ASC code conversion unit, etc.
