Using JAVA for process control requires the access to I/O-Hardware. This problem is addressed in several ongoing standardisation efforts for Real Time Java. A spin-off of these standardisation efforts is the Siemens product JFPC (Java for Process Control), which is based on the ideas of OPC (OLE for Process Control). It is available under the proprietary RT kernel RMOS and under Windows NT. Based on a contract with Siemens, ZEL - the central electronics facility of Forschungszentrum Juelich - has implemented JFPC under Linux. Additionally, several JFPC providers accessing industrial components via PROFIBUS DP have been implemented. The paper will present the status of the different standardisation efforts for Real Time Java It will describe the structure of JFPC and its implementation under Linux. Experiences and performance results will be discussed.
