Hi guys

Im currently running into an issue installing AS4.12.8.41 on a clean Windows 11 installation.
My project was building and running on the same installation on Windows 10 just fine, throws the following DTM warnings and errors.

Warning - The configured placeholder DTM is not installed on the system. Therefore no placeholder DTMs will be inserted by the scan for unknown devices.
Warning - Unable to export configuration.
Error - No data was exported from the supplied DTM.

IODD DTM Configurator shows no issues with the file.

I already tried the following steps:

  • unload and reload the DTM file
  • delete hardware component and insert it again
  • uninstall the complete AS solution and reinstall it
  • uninstall the B+R DTM Software and install the newest version from br-automation website

I’m currently out of options and would be grateful for any suggestions from the community :wink:

Hi guys

With the help of B&R Support we found the solution…
Older Versions of DTM require .NET 3.5

This can be checked with PowerShell command “Get-WindowsOptionalFeature -Online -FeatureName NetFx3”

It needs to show “State” → Enabled

.NET 3.5 can be enabled via the “Windows Features” settings.

Next restart your system.
Delete and reload the IODD file with the B&R tool IODD DTM Configurator.

Now, the errors should disappear.

Cheers
