We are using the OPC COM Tunneler to access tags in an OPC DA 2.0 server. One of the tags we need to access is, according the the device vendor, a two dimensional array. It appears the OPC COM Tunneler cannot read this tag. I have done some research and I can’t seem to locate any client that can …

You might try a different tunneler, such as this one: https://www.unified-automation.com/products/wrapper-and-proxy/uagateway.html I have very little OPC Classic experience so I’m not sure I can be much more help.

If needed, could @Colby.Clegg help or know more?
