ProtoLink enhanced a client’s existing process control application by giving it the ability to expose the collected data to 3rd party applications through OPC.
A company that specializes in signature-based process control approached ProtoLink to discuss extending an existing application that performed high speed data collection and display. After analyzing both the capabilities of their current application and their target market, ProtoLink determined that the best solution was to enhance their existing application by giving it the ability to expose collected data to third party applications through OPC.
ProtoLink implemented a multithreaded architecture to efficiently transform the application into an OPC server, using memory-mapped files to transfer the data from the hardware interface thread to the user interface and OPC server threads. ProtoLink personnel also provided support in DCOM configuration and troubleshooting.
