MLPrfReadIOffset
Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Returns the Input Offset value of a selected CAM Profile The position of a slave axis is mathematically linked to the position of a master axis. Example: A system where two rotating drums turn at a given ratio to each other. A more advanced case of electronic gearing is electronic camming. With electronic camming, a slave axis follows a profile that is a function of the master position. This profile need not be linear but it must be a mathematical function..

Returns the Input Offset of the selected CAM Profile. |
Remarks
- Offsets can be changed on the fly to modify the CAM Profile while maintaining its shape.
- A change in input offset is equivalent to shifting the CAM Profile on the X or Input Axis.
