Abstract

A machine interlock and protection system used for CYCHU-10 compact cyclotron was developed.The distributed hardware structure consists of SIEMENS PLC as the central device and monitor computer.The bus between PLC and remote partner is PROFIBUS.The program is realized by S7-Graph language using structured design method.The reliability,maintainability and expandability of the system are enhanced with the advance hardware and optimized software.The result of the application indicates that the interlock system can integrate subsystems of the cyclotron effectively and the security of system is improved.
