ReadMultipleItems documentation: www.opclabs.com/files/onlinedocs/QuickOpc/Latest/Reference/Q...e97-51b2-5eff-394ade5fb64f.htm

In short, the server identification is in the ServerDescriptor property inside each element (DAReadItemArguments: www.opclabs.com/files/onlinedocs/QuickOpc/Latest/Reference/Q...417-103a-2c5c-a623fa258780.htm ) of the input array. In the MachineName property of ServerDescriptor, you can have a computer name, but it can also be a numeric IP address, expressed as a string.

You need to construct an array of DAReadItemArguments, and in each of them, specify what you want to read and how - including the server address.

I hope this helps; if you run into problems, let me know.

Hi, I am using your Quick OPC C# library for building an evaluation application before making a purchase, I was wondering How can I connect to the OPC server running on other machine when I am trying to read multiple values. When I use DAVtqResult[] results = client.ReadMultipleItems(PROGID, Item); method there is no overload for mentioning the server IP address. Please help
