I am using Kepare to create an OPC UA Connection to a plastics press. I know very little about OPC UA outside of the configuation. Far as understand it to make a connection you simply open some ports and pretty much browse to the the tags you want. I posted a photo the error pretty much showing the process.
So I can select tags when I browse to the PLC. I select the ones I want then I click OK. To check my tags I run the OPC QC and I get the error noted. The actual error is "Expected data is unavailable for the requested time range due to an un-mounted volume". If anyone could provide some insight it to what this errir I would really appreciate it." I don't know if it is client side or a server side issue.
The Error Mean : "BadDataUnavailable" that is not much help to me.
I would like to know, in human terms, what the error is and what could be causing it. I would really apprcate any insight you could provide.
