January 2002 OPC Interop Workshop At this year's workshop, we tested the Instrumentation ActiveX controls' OPC client capabilities against a wide array of OPC servers. The primary functionality we tested was subscription reads as that is how these ActiveX controls get their data from OPC servers - via subscribing to the tags of interest.  The entire workshop was done via DCOM connections over a 100 Mb network with all client and server machines on the same subnet ( approximately 60 computers ). Below is a list of the OPC servers that we tested with. If you want to discuss the particular results with a server listed, please contact us. Out of respect for the OPC server vendors, we are not publishing their failures here for they may have remedied them by the time you visit this page.  If your OPC server vendor is not listed it does NOT mean that our Instrumentation ActiveX controls will not work with it - if the OPC Server follows the specs, these ActiveX controls should work fine all the same. It only means that vendor was not present at the Interop Workshop. If your OPC Server vendor has never attended an OPC Interop workshop, you as their customer should encourage them too -- it's a great technical session and a great opportunity for them to test out their products with others - we'll be there doing the testing so you as the customer don't have to! We tested with the following OPC servers. If you will be using one of these servers and wish to discuss any server side issues that were seen (that may be resolved by now by the server vendor), please contact us.  ABB Inc Process Portal Server ABB Inc Quality Control Object Server (AccuRay) Amersham Biosciences UNICORN 4.1 Aspen Technology Inc.
