The system of position control is quite different in Beckhoff compared to Siemens.
In a Beckhoff controller with Beckhoff drives on Ethercat, the CSP profile transmits each cycle the position to the drive. The drive interpolates and generates a velocity from that position signal.
In siemens with drives on Profinet, when DSC is used, a velocity signal is sent to the drive as velocity precontrol and a position error is sent to the drive for positon control in the drive.
Does someone knows the pro's and con's of both system?
