Status of the National Synchrotron Light Source Control System
The control system for the National Synchrotron Light Source is implemented using dual central computers and many remote microprocessors. This paper describes developments in four areas: 1) System organization. 2) Hardware status, particularly control desk and operator support facilities. 3) Central computer software system organization to support data base structures and access, and communication between application programs and hardware. 4) High level control programs which allow the operator to examine and control the transport lines and rings in terms of beam and machine parameters using mathematical models of the system. The output of these programs can be viewed on a color graphical display.
