OPC UA: allow historical data access
allow historical data access with custom time ranges, like OPC HDA
We have a feature in the upcoming 1.2 release of the connector that will allow you to collect data from OPC UA tags that do not have current values but do have history. We would poll these every 60 seconds (default) to find new data.
Was that part of this request in any way? Can you describe in more detail what you would like as a feature that prompted you to vote for this time?

Hey Chris, the OPC HDA interface allows back-filling by entering a custom time range, ie start and end time. The OPC UA Connector with historical access does not allow this; it starts back-filling at the last time it lost connection to the UA server, back-fills and then begins its realtime historical retrieval. The customers would like the ability to back-fill using a custom timerange, like the OPC HDA interface.
