Unable to read STRING data from OPC UA server using RUT951

Networking Solutions Issue
1

I am using a RUT951 as an OPC UA client to read data from a Turck PLC (TBEN-L4-PLC-11).
Issue:
The RUT951 cannot read STRING values. The result is always empty.
Other data types such as BOOL, INT, and REAL are working correctly.
I have tested the same OPC UA server using UAExpert, and STRING values are read correctly.
Question:
Is this a limitation of the RUT951 OPC UA client, or is it a known issue?
Is there any configuration or workaround to read STRING values?
Thank you,
