Stein, S J

The Personnel Safety System for the experimental beamlines at the Advanced Photon Source will use a large number of Allen Bradley Programmable Logic Controllers (PLC) to replace conventional relay logic. PLCs allow for the design of a very advanced safety system that can handle a large number of I/O points. Certain situations Require monitoring of the safety system from various locations around the storage ring via EPICS OPI (operator interface)consoles. This presentation covers the method of choice for transferring data from the Personnel Safety System into an EPICS database. Specifics on PLC ladder design, EPICS database design, and hardware selection are also discussed.
