This paper describes a machine interlock and protection system used for accelerators based on EPICS (Experimental physics and industrial control system). The system is composed of a front-end computer and an FM-3R logic controller PLC. The alarm signal is passed by the hardware directly
and would be deal with PLC. The reporting
recording and analyst of the event are accomplished by EPICS control software. And PLC is linked to the EPICS by Internet.
