MC_CamOut	Deactivates a master-slave coupling.
MC_CamIn	Activates master-slave coupling with a certain cam plate.
MC_CamScaling	Scales a cam plate coupling.

Multi Cam Plates

Function Block	Description
MC_CamIn_V2	Several cam plates can be superimposed.
MC_CamAdd	Adds a cam plate to a multi cam.
MC_CamExchange	Exchanges a cam in a multi cam.
MC_CamRemove	Removes a cam from a multi cam environment.
MC_CamScaling_V2	Scales a cam plate coupling.

Motion Functions

Function Block	Description
MC_ReadMotionFunction	Read the data of a motion function.
MC_ReadMotionFunctionPoint	Read the data of a motion function interpolation point.
