	We introduce the control system of the SuperKEKB collider which is based on EPICS. We standardize the CPU module so that we easily maintain our huge control system. Most Input/Output Controllers (IOCs) installed along the 3 km beamline at SuperKEKB are developed with only two kinds of CPU module. In addition to providing standard IOC for individual hardware, we develop some beam operation system which promotes the beam commissioning. The alarm monitoring system, abort trigger system, and Beam Gate system are developed by the control group. The sophisticated Beam Gate system for positron beam controls operation of both damping ring and main ring. It obviously promotes the beam commissioning at those rings. The other highlight is the precisely synchronized control system. It is necessary to realize the highly complicated control of beam injection process. We configure the dedicated network with the Event Timing System and the distributed shared memory. The distant hardware components are synchronously operated with this network. The beam commissioning of SuperKEKB has been started in 2016. The control system supports its fruitful beam operation without serious problem.

	Funding: Work supported China Scholarship Council 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.

	The timing system of SuperKEKB accelerator is used Event Timing System developed by Micro Research Finland. In this presentation, we tested the receiver on Zynq7000 evaluation board. The serialized event data are transferred from Event Generator to Event Receiver by using GTX transceiver. So, we selected Zynq7000(7z030) as receiver, because the FPGA has the GTX. And also, Zynq is mounted on arm processor, it is easily able to control received event data stream by using EPICS ICO. Finally we are aiming to combine event system and RF or BPM system in one FPGA board.
