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
Spline Download Area for this example, you need only write two blocks of data to the RMC's Spline
Download Area. First, you would write the following data to give the count and time intervals.
Addresses are given in Modbus (RTU, TCP, and Plus) format. See Downloading Splines to the RMC
for other communication module addressing formats.
Address Value Description
12289 1 Format of interval data (one value per interval)
12290 400 Interval between points 0 and 1
12291 200 Interval between points 1 and 2
12292 200 Interval between points 2 and 3
12293 200 Interval between points 3 and 4
12294 200 Interval between points 4 and 5
12295 200 Interval between points 5 and 6
12296 200 Interval between points 6 and 7
12297 400 Interval between points 7 and 8
Now that the RMC knows the number of points we will download and the intervals between these
points, we can download the point positions:
