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.

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
  • n July 2017.
