Looks like the HMI components are not found or cannot be loaded at design time.
Updating the NXRD file was a good idea. Just to make sure: Have you used an HMI version matching the CpStudio version? (Only the first two places are relevant, patches are compatible. e.g. CpStudio 5.8.x works with HMI 5.8.y)
Is your project (including the Std folder) located on a local drive? I have seen this problem (or at least a similar one) when projects were located on a network drive.
Next you could check some files in the <Station>\Hmi folder:
The file OpCon.HMI.Modulo.csproj contains reference paths from the Hmi folder to the dll files in the Std\Hmi_Vx_y looking like this:
<Reference Include="OpCon.HMI.Interfaces"> <HintPath>..\..\Std\Hmi_V5_8\OpCon.HMI.Interfaces.dll</HintPath> <CopyLocal>True</CopyLocal> </Reference>
The red path has to be correct (especially the version). The paths are automatically adapted when updating a project to a later CpStudio version, so they should usually be correct, but when using Source Code Control systems and not committing everything, the files can be inconsistent.
In the same folder, check the file VisiWinNETSmart.config. It also contains information about the HMI files:
<Assemblies> <Assembly alias="OpCon.HMI.Modulo.Forms" assembly="OpCon.HMI.Modulo.Forms, Version=5.8.0.0, Culture=neutral, PublicKeyToken=4241dc8872ae9833" /> <Assembly alias="OpCon.HMI.Modulo.StdWindows" assembly="OpCon.HMI.Modulo.StdWindows, Version=5.8.0.0, Culture=neutral, PublicKeyToken=4241dc8872ae9833" /> <Assembly alias="OpCon.HMI.Modulo.Shared" assembly="OpCon.HMI.Modulo.Shared, Version=5.8.0.0, Culture=neutral, PublicKeyToken=4241dc8872ae9833" /> </Assemblies>
Again, the red versions should be automatically adapted when converting a project.
Apart from that, we have had issues with files that were downloaded from an untrusted source (Internet, SharePoint, other shared storages). Usually I would think that this also causes errors on the target system, but who knows...
