The PF (Poloidal Field) control system is one of the most important control systems in HT-7 Tokamak. Most of parameters such as plasma current, plasma horizontal position and plasma vertical position will be monitored. For the purpose of long-pulse discharge and the more precise control to plasma, the real-time operation system VxWorks is applied, instead of the behindhand and unbefitting DOS operation system. This paper describes the de- velopment process of HT-7 PF control system based on VxWorks on Intel X86 platforms. The method of using hard- ware cards in VxWorks, and the network communication with other operation systems are discussed especially. Re- sults of the comparison between VxWorks and DOS operation systems are given too.
