The system control center, PLC CPU module

The CPU module is the control center of the system, the user will be prepared to complete the program is downloaded to the CPU module, the CPU module after the start of a cycle of user program execution, each cycle should be read into the process information, cpu modules plc  logic calculation, output calculation results, but also the timing or by user set time, high-speed counting, event processing and communication interrupt process.

The powerful LK PLC, is the first large-scale programmable controller, system
implementation experience based on Hollysys company has accumulated fifteen years of research, high-speed counter modules development and engineering control system, in-depth study and absorb the essence of the international similar products, PLC years of intensive and meticulous farming.
