NI Motion Controller Architecture

Functionally, the architecture of the NI 73xx motion controllers and the NI SoftMotion Controller is generally divided into four components: supervisory control, trajectory generator, control loop, and motion I/O. For the NI SoftMotion Controller, the motion I/O component is separate from the controller. The following figures demonstrate how the components of the 73xx and NI SoftMotion Controller interact.
