1. An on-machine diagnostic logging system comprising:
- interface circuitry for receiving control and monitoring signals from machine control devices that control or monitor operation of a machine system;
a processor for receiving the control and monitoring signals from the interface and for processing the signals at least partially independently of a remote control and monitoring system; and
a memory circuit for storing the control and monitoring signals received by the processor;
wherein a subset of the control and monitoring signals are transmitted to the remote control and monitoring system, and the diagnostic logging system receives and stores signals not part of the subset, and wherein the interface circuitry is configured to be interrogated for access to control and monitoring signals stored in the memory circuit.

Abstract
A logging system is provided for a distributed automation application, such as an on-machine motor controller or the like. The logging system can access raw data, processed data, event data, error data, and so forth from a controller local to the applicational power to a load, such as an electric motor. The logging system can also access information and place information on a network to which the controller is linked. Logging system may also monitor and log data directly from sensors. Information and data stored in logging system may be interrogated and accessed either remotely via a network, or locally, such as through a local access port.
