Abstract: A method and system for communication between a motor controller and an analytic module includes a Single Pair Ethernet interface with power supplied over the two data lines. The analytic module, in turn, connects to a motor or other devices proximate the motor. The analytic module receives input signals from the motor or different types of sensors or devices. A processing unit in the analytic module may perform some initial processing on the incoming data. The processing unit is configured to transmit either the raw input signals or processed data via the Single Pair Ethernet connection back to the motor controller or to other controllers in the system with the motor controller acting solely as a pass-through gateway. The analytic module unit may be configured to transmit data at different update rates. One of the update rates may be synchronized to an update period in the motor controller.
