Abstract

A system that enables controlling motion over a network comprises an interface that receives motion control data that includes a time stamp from the network. Additionally, the system includes a motion control component that utilizes the received motion control data to update properties associated with the motion control component based at least in part on the time stamp. The system can also include a clock that is synchronized with disparate clocks associated with disparate motion control components located on the network.
