Working Principle
After power initialization, the CPU runs the system operating system and user application programs in real time. It cyclically collects data from each I/O module via the backplane bus, executes control logic and motion algorithms, and sends control commands to the execution modules. At the same time, it completes data interaction with external equipment through the communication interface, and records system operating status and fault information in real time.
