With SINAMICS Integrated, all frames must be operated in isochronous mode on OB Servo
(OB 91) or isochronous mode interrupt OB (OB 6x). STEP 7 checks compliance with this

Exception: If you insert a SIMATIC Drive Controller in your project from the module

configure any other drive objects, you can also compile and download to the device
without isochronous mode.
