errors with HistoryReadRawModified on UAexpert 1.2.2-175

[dasamara]

Hello,

We are using UAexpert OPCUA client with a COTS OPC-UA server product that supports historical data access. However, with UAexpert 1.2.2 175, there is always an error "HistoryReadRawModified has bad status BadServiceUnsupported".

Upon my request, the vendor of the COTS OPC-UA server we are using has tested their application with UAexpert 1.2.2-175 as well as an older version -- UAexpert 1.2.0-132.

It appears that the historical data access works properly with 1.2.0-132, but not with 1.2.2-175.

Can you help us understand if this makes sense based on your knowledge of the changes to UAexpert between these versions?

Hello Dean,

between UaExpert versions 1.2.0 and 1.2.2 nothing changed in the way HistoryReadRawModified is being called. If possible, please contact the vendor of the UA server again for checking the behaviour on server side if this UA service is being called.

Best regards
