Fail safe upgrade of Interlock system HMS redundancy limit switch replacement Controller modification Keep CPU usage below 70%. • Utilized Watch dog • Control System upgrade 12 National Synchrotron Radiation Research Center
Fail safe upgrade of Interlock system 13 National Synchrotron Radiation Research Center
Redundancy PLC and PAC controller setup Transferred all compact RIO I/O node • from Real Time to FPGA. Programmed watch dog monitor • function by RT sub VI. This function enabled to output an alarm signal to FPGA if RT time out. Continue to Program I/O node valid • monitor, CPU loading monitor and failed signal output is wiring. 14 National Synchrotron Radiation Research Center

Conclusions 1. 6 insertion device beamlines have been available for user operation after safety interlock systems commissioned and reviewed. 2. After fail safe upgraded , a YOKOGAWA FAM3 PLC as a redundancy system which used to monitor NI cRIO 9030 status and enable to switch off TPS FE if cRIO 9030 failed. 3. In order to enhance the stability if FE interlock system, all PPS and MPS logics from RT system to FPGA are changed. 4. All FE interlock system will be upgraded on July 2017. 16 National Synchrotron Radiation Research Center
