Figure 7-2. Contoured Move Algorithm

Clear the buffer that stores

contoured move points

Start Motion

Configure the buffer

on the device

Perform Measurements

(Optional)

Set Operation Mode

Specify absolute or

relative contouring

Check the buffer on the device

Number of points consumed

Write Buffer

Write remaining points

to onboard buffer

Write Buffer

Write the array of points and the
number of points you are writing

Restore Operation Mode

Set operation mode back to absolute

position to clear contouring data

• Set the Buffer Type as Position

Total Points is the total number of
countoured points you want to load
Buffer Size is the size of the buffer you
want to create on the device
• Set Old Data Stop to TRUE if you do
not want old data to be used
Requested Interval is the time interval
between points
