In order to obtain high quality products many sensors are included into modern production systems. The Information Sharing Platform (ISP) is a software tool, which allows recording, storing and analysing of the data obtained from different signal sources. Due to its modular structure with standardized interfaces, individual connector plug-ins can be implemented, so that the ISP can connect to every sensor system, machine control and data acquisition system on the market. High sophisticated knowledge extraction algorithms can be implemented within this tool for online and offline data processing and analysis. User defined algorithms and functions can be loaded at runtime.
