  Sungkyunkwan University groups have been developed advanced radiation therapy machine named dual-head radiation therapy gantry for reducing the treatment time by up to 30%. The main difference between previous radiation therapy machine is using two electron LINAC as X-ray sources at radiation therapy. In support of this system, control system based on SCADA and hardware development was implemented. The control system consists of supervisory computers and local controllers and the control network was ethernet and software was written by labVIEW. An overview of this control system is presented in paper.

  Ethernet POWERLINK (EPL) is a communication profile for Real-Time Ethernet. The communication profile meets real-time demands for the distributed system composed of multiple controllers. EPICS is a wildly used distributed control system in large scientific facilities. We design a distributed IO system based on EPL under the EPICS architecture and establish the prototype system composed of a PC and six FPGA boards. In this system, an EPICS driver based on openPOWERLINK is developed to monitor the system status. In this paper, the communication mechanism of EPL, the design of system architecture, the implementation of EPICS driver and the test results of prototype system will be described.
