Does anyone have experience with the Qt OPC UA Viewer application given here? With this application, using the open62451 backend, I am able to connect to the OPC UA server on ctrlX CORE and read nodes, but I am unable to enable monitoring. Typical log output is: Warning: Could not add monitored item for QOpcUa::NodeAttribute::Value of node "ns-2;s=plc/app/Application/sym/UserVarGlobal/Value" : BadInternalError This issue is not present on other OPC UA servers that I have tried, including the server on XM22 (14VRS firmware), the sample OPC UA C++ Demo Server (Windows) available from Unified Automation, and the public simulation server available here from Prosys. In these cases I can connect and enable monitoring successfully. See attached videos. UaExpert connects and monitors nodes on ctrlX CORE successfully and I have tried to implement the settings used there in my Qt OPC UA Viewer source -- all to no avail. See images below. The ctrlX CORE server settings and debug output verifying the monitoring parameters are attached. If anyone can shed light on this issue, it would be greatly appreciated. Qt 6.4.2; open62451 Git-Revision: v1.1.2-8-ge941fc23; OPC UA Server app 1.18.1
