@Jan_Zimmermann : Would be interesting to understand which interface cards are present inside the ACOPOS (one seems to be the resolver card 8AC122.60)
Most probably the first card inside the ACOPOS is the 8AC140 which is plug-in CPU which has onboard also an ProfibusDP interface.
This would be the link to the GSD package for this type of CPU ( 8AC140.6x-x GSD Package | B&R Industrial Automation)
