On opening a project in PowerConnect, you get the error:
Problem in TMaterial.ReadFromXMLDoc.
The requested value BS_5950 is not found
[NL]: De aangevraagde waarde BS_5950 is niet gevonden.
The project you’re trying to open was made in version 2018 (or newer), while you try to open it in 2017 (or older). BS 5950 is a British standard implemented in 2018. Older versions of Diamonds don’t recognize it resulting in the error.
