PLC programming is an electronic system for digital operations, designed specifically for use in industrial environments. It uses programmable memory to store instructions for executing logical operations, sequential control, timing, counting, and arithmetic operations internally, and controls various types of mechanical or production processes through digital and analog inputs and outputs. Programmable controllers and related equipment should be designed according to the principle of easy integration of industrial control systems and easy expansion of their functions.
With the rapid development of microprocessors, computers, and digital communication technology, computer control has expanded to almost all industrial fields. Modern society requires the manufacturing industry to respond quickly to market demand, producing small batches, multiple varieties, multiple specifications, low costs, and high-quality products. In order to meet this requirement, production equipment and automatic production line control systems must have high reliability and flexibility. PLC programming is a universal industrial control device based on microprocessors, which meets this requirement
PLC operates in a “sequential scanning, continuous cycling” manner. When the PLC is running, the CPU compiles a program that coexists in the user’s memory according to the user’s control requirements, and performs periodic cyclic scanning according to the instruction step number (or address number). If there are no jump instructions, the user program is executed sequentially from the first instruction until the program ends, and then returns to the first instruction to start the next round of new scanning. During each scanning process, We also need to complete tasks such as sampling the input signal and refreshing the output state.
