1. An industrial device, comprising:

  • a memory that stores executable components;

    a processor operatively coupled to the memory that executes the executable components, the executable components comprising;

    a cloud interface component configured to communicatively couple the industrial device to a cloud platform that executes a motion planning system, to send feedback information indicating a current state of an industrial motion device to the motion planning system via the cloud platform, and to receive, from the cloud platform, a coarse interpolated motion profile generated by the motion planning system based on the feedback information, the course interpolated motion profile defining a trajectory as a set of position or velocity values over time at a first update rate;

    a synchronization component configured to synchronize an internal clock of the industrial device with a master clock associated with the motion planning system;

    a fine interpolation component configured to interpolate additional position or velocity values between the set of position or velocity values to yield a final motion profile comprising an updated set of position or velocity values over time at a second update rate that is greater than the first update rate; and

    a control component configured to control motion of the industrial motion device in accordance with the final motion profile.
