The data structure for parameterization of a digital cam controller is usually an ARRAY OF MC_PathCamSwitch. A further structure PATH_CAMSWITCH_REF refers to this structure.

Name	Type	Description
FirstOnPosition	LREAL	First position from which the cam is switched on.
LastOnPosition	LREAL	Last position up to which the cam is switched on. The cam function is inverted, if LastOnPosition < FirstOnPosition. LastOnPositionis is not used for time cams.
FirstPathId	UDINT	Unique ID that continually increases over the path and belongs to the relative path until the cam switches on.
LastPathId	UDINT	Unique ID that continually increases over the path and belongs to the relative path until the cam switches off.
CamSwitchMode	E_CamSwitchMode	Digital cam type (position cam, time cam or brake cam).
Duration	LREAL	Duration defines the switch-on time of the cam in [s] and is only used for time cams.

TYPE E_CamSwitchMode :
(
    CAMSWITCHMODE_POSITION, (* position cam *)
    CAMSWITCHMODE_TIME,     (* time cam *)
    CAMSWITCHMODE_BREAK     (* break cam *)
);
