Hi All


I have a question related to OPC DA and HDA. PI OPC DA interface gets data directly from OPC server but HDA server is an intermediate i.e. instrument ID is different for OPC DA and OPC HDA. I would like to know best possible ways to use OPC HDA if OPC DA is offline or failed. As instrument id is different for OPC DA and HDA interface(getting data from different OPC server). Is there any way to configure OPC HDA inteface to get data for the same points with different item id?
