Hi @pturmel
Thank you for your comments
- The tags are set to discrete for the historian
- The OPC UA client never lost connection, only the edge to the central gateway (which hosts the OPC-UA client). We understand that OPC-UA HA is not implemented, but queues are implemented and should buffer the data as specificed and requested by the client.
- Thats the options we checked, but it was not working as expected. We found something in the documentation which explains the issue and will now check if the interval sample mode without interpolation works:
Does anybody know why there are gaps in the tags exposed via OPC-UA after flushing the data from the edge? The most historical data can be exposed via OPC-UA, but there are these longer gaps (15-20sec) which are not explainable for us.
Is there maybe a queue between an Ignition Tag and an OPC-UA node which gets full before the OPC-UA server is able to publish the data? Just a guess
