Building a high power spallation target is one of the critical issues in Accelerator Driven System (ADS). The control system which was built based on the real-time distributed control software of experimental physics and industrial control system (EPICS) was attempted for the experimental target prototype. There are several sub-systems in the target system, e.g. the elevating system, the vacuum system, the heat-exchanging system. As an IOC, each sub-system was finally integrated into the control system of the target by different drivers and methods because different hardware devices were used for each sub-system. The ’SLS s7 driver’ which was devel-oped based on the Ethernet Interface was used for the communication between the Siemens PLCs and the Hu-man Machine Interface (HMI). The interfaces between Labview and EPICS were used for the NI (Nation-al Instruments) DAQs systems. In addition, the driver developed by ourselves was used for devices with serial ports, e.g. RS-232 or RS-485/422. The control system was finally proved stable and could basically meet the ele-mentary requirements of the spallation target system.
