Abstract
A bus-oriented computer control system has been developed for manual and automatic operation of cyclotrons. The bus is a noise-immune, optically isolated extension of a DEC LSI-11 computer bus. This simplifies the software since each device register is addressed as if it were a computer memory location. Thus the full range of PDP-11 instructions can be used to operate directly upon any cyclotron data location. Standard modules have been designed to interface power supplies and other cyclotron subsystems to the bus. They perform the functions of ON/OFF control, monitoring of interlock status, control of analog variables, and analog data acquisition. All digital data output to a subsystem can be read back for verification.
