abstract = {The new MRF event timing system is one of the most important components to maintain the reliable and stable operation of the SuperKEKB project. This system is utilized to distribute high precision level timing signals and accompanying control instructions to synchronize different subsystems and machines. Event generator (EVG) generates signals of different beam modes every 50 Hz pulse which contains several event codes while Event receivers (EVR) receives them and output signals to dedicated devices all over the installation. To certain these events are consistent during the distribution, an event fault diagnosis system is essentially needed. An EVR based event timing diagnostic system is thus developed by modifying the driver support module to provide a log system of persistent event data as well as comparing the received event codes with the beam injector pattern, detecting the event timing interval fault and notifying the results by email every day. Then, we are able to locate the fault, analyze the data, fix bugs or replace hardware and resume accelerator operation quickly.},
