Master Cam input: Master signal at the curve input
(C3Cam.StatusMaster_PositionCamUnits o3030.24)
Master signal: Master signal of the acquisition (C3Cam.StatusMaster_Position
o3030.1)
Slave: Signal at the curve output (C3Cam.StatusOutput_CurvePositionUnits
o3032.24)
Only with absolute master reference, a given curve can be started at any position.
This position corresponds to the offset value if the events "Start Source
C3_MasterControl" and "Start C3_CamTableSelect" take place at the same point
in time. Alternatively, you can preset the start value of the master position
acquisition with the C3_SetMaster.
Typical application: Shifting an open, s-shaped curve in the master reference
system.
The offset is added to the current value of the master signal at the start time of
CamTableSelect.
Relative slave reference
Relative slave reference can be established with MC_CamIn.
