4.1 CANopen – Communication profile
The CANopen communication profile (defined in CiA DS-301) regulates the devices
data exchange. Here real time data (e.g. position value) and parameter data (e.g.
code sequence) will be differentiated. To the data types, which are different from the
character, CANopen assigns respectively suitable communication elements.
