Does anyone know of a good way of getting a display name without running a browse via system.opc.browse (or browseSimple)? My available inputs are opcItemPath and opcServer.
Hmm, I don't think this is possible any other way. The only time the DisplayName attribute is read is during a browse, and there isn't a way to read anything but the Value attribute via scripting.

For the ignorant among us, what is an "OPC display name"?
It's an attribute of the OPC tag available on the OPC server containing a string alias for the tag, accessible by running a method on a system.opc.browse output
