Generation of new ar-config fails when trying to configure io-mapping

Hi guys, I’m new to B&R and working on a project for my bachelors degree which involves the usage of mappIO.
I’m trying to create a completely modular ar-config with new io-mapping.

If I load a xml-file which only changes the ar-config, the new config generates without any issues. It’s only when I try to change the IO-mapping of the inputs or outputs of a module MpIOImport gives out an error. (-1064120318 Error creating import data)

This is an example of a xml-file which results in a properly generated ar-config and
another xml-file which results in an error upon loading onto the CPU.

(the Master Configuration Value of MpIOImport is set to None)

I had several ideas about what causes this behaviour but ruled out the simple ones and to be honest I lack the deeper knowledge to really nail down or explain the problem any further, which is why I am here.

For hints of any kind or a simple nudge in the right direction I would be forever grateful!

Hi,

first, I would propose to check the logger. Some mapp components add additional info about the error cause into the logbook.

Best regards.
