Replied by support on topic Reading multiple items from a remote server
Hello,

you need to use an appropriate overload of the ReadMultipleItems, for example:

[]).html

And you can construct the ServerDescriptor using a machine name and a ProgID: opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...ptor~_ctor(String,String).html

Let me know if you need further help with that.

Best regards
