5SHY3545L0014 3BHE019719R0101 Divide a total control objective program into several program modules with well-defined sub-tasks, write and debug them separately, and finally combine them into a complete program that accomplishes the total task. This method is called modular programming. We recommend that this program design ideas are often used, because the modules have a relative independence, the interconnection relationship is simple, the program is easy to debug and modify. Especially for complex control requirements of the production process.

5SHY3545L0014 3BHE019719R0101 control system programming points. PLC control system I / O allocation, based on the production line from front to back, I / O points from small to large; as far as possible, a system, equipment or components of the I / O signals centrally addressed to facilitate maintenance. Timer, counter to a unified number, not repeated use of the same number to ensure the reliability of the PLC work operation.
