The data structure for parameterization of a digital cam controller is usually an ARRAY OF MC_CamSwitch. A further structure 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.
AxisDirection	E_CamSwitchDirection	AxisDirection defines in which axis travel direction the digital cam is active (positive, negative or both directions).
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_CamSwitchDirection :
(
    CAMSWITCHDIRECTION_BOTH,     (* digital cam will work in both directions *)
    CAMSWITCHDIRECTION_POSITIVE, (* digital cam is just working in positive direction *)
    CAMSWITCHDIRECTION_NEGATIVE  (* digital cam is just working in negative direction *)
);
END_TYPE

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