Abstract

Systems and methods for synchronizing motion connection communication to time-aware network for industrial systems. One system includes an electronic processor configured to determine a controller Qbv configuration for an industrial controller included in a TSN. The electronic processor is also configured to determine, based at least in part on the controller Qbv configuration, a first start of a Qbv slot for isochronous traffic for an industrial device included in the TSN. The electronic processor is also configured to adjust, based at least in part on the first start of the Qbv slot for isochronous traffic for the industrial device, network scheduling for the industrial device. The electronic processor is also configured to deploy the adjusted network scheduling to the industrial device.
