OPC UA Historical data

[Johnny07]

Hello, i am testing with an OPC UA simulator (PLCNext).

i am able to get realtime data from the (Virtual) PLC  write values to the (Virtual) PLC.

for us it is neccesary that in case of communication loss, data is saved on the PLC and when the connection is back the data needs to be collected in Geoscada.

I was able to store this data on the (Virtual) PLC, and i can read it with UaExpert as historical data.

im am not able to get this data in Geoscada, is it possible to get this (missing) data in GeoScada?

If yes what configuration must implement?

Greetings,

Johnny

The Geo SCADA OPC UA client driver supports the "Data Access" specification (part 8), it doesn't support the "Historical Access" specification (part 11).
