Hello,

you can find this out yourself by constructing a ServerDescriptor, settings its Host property, and serializing it into XML.

The information you need will be contained in the same UrlString element as you have listed above, and will look similar to this:
  • opcda://hostNameOrIPAddress/OPCLabs.KitServer.2

subscribing to multiple tags using xml on remote server was created by rotem
Hi,
i on upgrading an 5.23 application to 2017.2, i have used the XML to build the list of tags
i have tried to use your sample of xml file to read multiple tags,
but in the example i havent found any parameter for server IP/HOST,
the SubscribeFromXml xml example:
<ServerDescriptor xmlns="http://schemas.datacontract.org/2004/07/OpcLabs.EasyOpc.DataAccess.OperationModel">
  <UrlString xmlns="http://schemas.datacontract.org/2004/07/OpcLabs.BaseLib">opcda:OPCLabs.KitServer.2</UrlString> 
  </ServerDescriptor>
what do i need to add for the server IP/HOST ?

in the 5.23 version i have added my own data fields into the xml, but the 2017.2 version is more strict on parsing, can i implement this here as well ?

Thanks
