Abstract
An improved system and method for monitoring operation of movers in an independent cart system reduces the required communication bandwidth for monitoring operation of movers in a system where control is distributed among multiple controllers spaced along the track. As the mover is travelling along the track segment, each distributed controller monitors at least one operating characteristic of the mover. As a mover travels along the track, each distributed controller transmits the operating characteristic to a successive distributed controller, such the monitored operating characteristic is transmitted along the track as the mover travels along the track. At a reduced rate or upon request from a central controller, each distributed controller may transmit the status of a mover present on the corresponding track segment controlled by that distributed controller to the central controller.
