Good day.
We have problems with the request to the OPC HDA server with the "Bounds"option. The HDA server WinCC needs to return the two correct values, but returns null values as "bad."
Found problem with clients: WinCC OA OPC HDA Client, Matrikon OPC HDA Explorer.
Screenshots of the test project with the request through the standard panel, and the log file are attached.
