The run-time data and machine parameters of the BEPCII is distributed over different platforms and stored with different softwares. Some is stored in various SCADA logging files, and some is stored in the EPICS archiver files. Now the EPICS data are stored in Oracle. No general method was provided to access these data. The OPC technology can solve this problem. Originally based on Microsoft's OLE COM (component object model) and DCOM (distributed component object model) technologies, the specification defined a standard set of objects, interfaces, and methods for use in process control and manufacturing automation applications to facilitate interoperability. We have developed EPICS/OPC Server and Oracle/OPC Server. With the help of these two servers and SCADA OPC Servers, it’s easy to get the data mentioned above on a Windows system. This paper describes the development of the two OPC servers and OPC applications at BEPCII.

In the upgrade project of Beijing Electron Positron Collider (BEPC)II, a novel DCS(Detector Control System) for the Beijing Spectrometer (BES)III is developed. In the system, nearly 7000 data points covering dozens of physical parameters need monitoring or control. The upper system is mainly developed by LabVIEW and OPC. The lower system mainly used Embedded system, MCU, and PLC, etc. These technologies reduced the cost greatly without any lose in system functions or performance. This paper will give a detailed introduction to the system architecture and advanced technologies we used or invented.
