A Fully CAMAC Interfaced Computer Control System for the Vicksi-Accelerators

The computer control system for the VICKSI-project uses CAMAC modules as the unique interface. A single loop CAMAC-Serial-Highway will control all the equipment associated with the accelerators and the beam paths. The components of the main-control-console as well as general maintenance-equipment are interfaced to the computer via a Parallel-CAMAC-Highway. No further submultiplexing is done. Special attention was given to the choice and specification of CAMAC-Modules in order to reduce the number of different types and to standardize the ports to the equipment under control. The impact on hardware (cabling, maintenance, error detection) and software design will be reviewed. The software itself is based on the use of a real-time executive in conjunction with an interpreter and a data base allowing a comprehensive addressing scheme and simple system tasks.
