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.
