In April of 2004, Software Toolbox attended the OPC Interoperability workshop in Los Angeles, CA. We tested the Instrumentation ActiveX controls' OPC client capabilities against the following OPC Servers. Do note that if your OPC Server is not listed, that only means that your vendor was not present for testing and does not mean that the IOComp controls are incompatible.
