In order to enhance the anti-interference ability of PLC and improve its reliability, each switch input terminal of PLC adopts photoelectric isolation technology.
In order to realize the hard logic parallel control of the relay control circuit, PLC adopts a different operation mode (scanning technology) from the general microcomputer.
The above two main reasons make the I/O response of PLC much more than that of industrial control system composed of general microcomputer. Its response time is at least equal to one scanning cycle, which is generally greater than one scanning cycle or even longer.
The so-called I/O response time refers to the time required from the change of an input signal of the PLC to the change of the relevant output signal of the system. The shortest I/O response time and the longest I/O response time are shown in the figure:
Minimum I/O response time
Maximum I/O response time:
The above is the working principle of general PLC, but in the relatively advanced modern PLC, the input image refresh cycle, the program execution cycle and the output image refresh cycle have worked independently, improving the execution efficiency of PLC. In the actual industrial control application, the programmer should know the above working principles in order to write a process program with good quality and high efficiency.
