5.3.1 Data flow
The characteristics (curves) are entered or imported in the »Cam Designer« by means of graphical
objects (point, line, polynomial). The transmission of the cam data to the controller(s) – together
with the corresponding parameter set – is effected via the »Engineer« by executing the command
Transfer parameter set to the device. Afterwards the parameter set and the cam data have to be sa-
ved in the memory module with mains failure protection (e. g. with the device command
C00002 = "11: Save starting parameters").

Tip!
The characteristics (curves) can also be entered directly via the parameters of the basic dri-
ve function "Cam data management" (LS_CamInterface SB) if cam data have already been
downloaded to the controller.
Selection of the cam data to be used within the application
Within the application the selection of the data to be used is then carried out via the product num-
ber and the track number which have been defined for the axis in the »Cam Manager«:
• The selection of the product number  is effected globally for the application via the input
CAM_dnProductNumber of the LS_CamInterface SB:
• The selection of the track number  of the characteristic, however, is effected individually via
the input dnTrackNumber of the corresponding entity of the L_CamCurve FB.
