Abstract
The Personnel Safety System for the experimental beamlines at the Adva nced Photon Source will use a large number of Alien Bradley Programmab le Logic Controllers (PLC) to replace conventional relay logic. PLCs a llow 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 t he EPICS OPI (operator interface) consoles. This presentation covers t he chosen method for transferring data from the Personnel Safety Syste m into an EPICS database. Specifications on PLC ladder design, EPICS d atabase design and hardware selection are also discussed.
