The optimizer must then send this spline segment to the motion controller. Assuming that the
optimizer cannot use RMCWin to download the spline, there are two methods of doing this. The
first is to use the Add Spline Point, Set Spline Interval, and End Spline Segment commands. The
second is to use the Spline Download Area. An example of the steps required to do each is
shown below:
Downloading with the Spline Download Area:
You should look over Downloading Splines to the RMC for details used in this example. To use the

for other communication module addressing formats.

Now that the RMC knows the number of points we will download and the intervals between these
points, we can download the point positions:
