Vacuum Control System Based On PLC Distribution In Large Laser Facility

摘要

In large and high power laser facility,vacuum system is composed of some independent subsystems,and every control subsystem is composed of PLC system. All vacuum pumps is controlled by controller of each component using panels or touch screens. Each sub PLC system and main PLC system compose large laser facility vacuum control system. Main control system uses monitor computer to control each subsystem and communicates with upper control system through Ethernet.
