1. A motor drive, comprising:
- a controller configured to generate a control or communication signal for transmission to a component of an automation system coupled to the motor drive; and
an interface configured to receive from the component an operational condition signal indicative of a fault in the component, wherein the controller comprises a processor configured to;
analyze the operational control signal;
access at least one rule comprising input information of a type of fault of the component;
determine a likelihood of a solution to remedy the fault causing the operational control signal utilizing the at least one rule; and
generate a weighted likelihood ranking value to be displayed on a display, wherein the weighted likelihood ranking value is related to the likelihood of the solution to correct the fault, wherein the weighted likelihood ranking value is generated utilizing weight information of the at least one rule.

Abstract
An automation network that utilizes motor drives to diagnose faults, and provide potential solutions to a user. The fault status and/or diagnostic remedies may be displayed via a user display integrated with (e.g., in a single cabinet with) the motor drives and/or coupled to (e.g., in an external device separate from) the motor drives. As such, a logic process or other algorithm may be executed by the motor drive to determine a potential set of solutions for any given fault, based on, for example, determined errors and likelihood of causes for presentation to a user. In this manner, motor drives may allow for user corrective actions to be communicated to a user.
