    摘要: Providing diagnostic functions for a distributed directory employed in an industrial control environment is described herein. By way of example, status of directory entries can be monitored, updated based on activity within the control environment, and propagated to entities coupled with the environment by way of distributed directory nodes. Directory entries can be validated over time and optionally flagged as valid or deleted if invalid. In some aspects, validation can occur via direct communication with entities coupled to the control environment. Changes to directory entries can be tracked, and can be propagated through the distributed directory. Further, automatic reconfiguration of control entities can be implemented based on the changes, resulting in a dynamic and self-adapting control environment.

    摘要: The claimed subject matter provides a system and/or method that facilitates employing safety within an industrial environment. An enhancing component can implement at least one of a security level, authentication, authorization, or an access right to a validated action to at least one of the controller or the controller engine instance. The enhancing component can further separate two or more entities within the industrial environment, the first entity related to process control and the second entity related to process safety. Additionally, the enhancing component can employ at least one of a backup controller or a backup controller engine instance in the event of at least one of a software error or a hardware error within the industrial environment.
