In operating mode, the PLC achieves control functions by repeatedly executing user programs that reflect control requirements. In order to ensure that the output of the PLC responds promptly to input signals that may change at any time, the user program is not only executed once, but continuously repeated until the PLC is powered off or switched to the STOP working mode.
The full Chinese name of PLC is Programmable Logic Controller, which is a digital operation electronic system designed specifically for application in industrial environments. It adopts a programmable memory that stores instructions for executing logical operations, sequential control, timing, counting, and arithmetic operations internally. It controls various types of mechanical equipment or production processes through digital or analog input and output.
In the input sampling stage, the programmable logic controller sequentially reads in all input states and data in a scanning manner, and stores them in the corresponding units in the I/O image area. After the input sampling is completed, it enters the user program execution and output refresh phase. In these two stages, even if the input state and data change, the state and data of the corresponding units in the I/O image area will not change.
