• performing a connectivity check to obtain CAN connection status data and ethernet connection status data for the plurality of devices;
• analyzing the CAN connection status data and the ethernet connection status data to determine one or more components of the industrial machine that are a likely cause of a device connection issue;
• determining a physical location of the determined one or more components within the industrial machine;
• and
• outputting a solution to the device connection issue to a user based on the analyzed data, wherein the solution provides the determined physical location of the determined one or more components.
