We have a some troubles with sample mode in tag history configuration.
We’re using a WAGO PLC that comes with his own OPC-UA server inside the PLC himself.
When we historize tags with sample mode “On change”, the date of the trend came from the PLC, but if we do it with “Tag group”, the date came from the ignition server.
We searched in the documatation but we didn’t find anything about it.
Do you have any information about this?
