Systems and methods for queuing an action in industrial automation systems

Abstract

The subject invention relates to a system and methodology facilitating automated manufacturing processes in a regulated industrial controller environment, wherein operator commands are tied to one or more signature requirements before the requested commands take effect in a batch system. In one aspect, a system is provided for signature processing in an industrial control environment. The system includes a queuing component to hold a pending request for an action. A signature component then determines when an electronic signature is completed for the action, wherein a batch processor executes the action from the queuing component after the electronic signature is completed. A policy component can be provided to define one or more conditions for completing the electronic signature.

Description

PRIORITY CLAIM[0001]This application claims priority to U.S. patent application Ser. No. 10 / 953,944, filed on Sep. 29, 2004, entitled “SYSTEMS AND METHODS FOR QUEUING AN ACTION IN INDUSTRIAL AUTOMATION SYSTEMS.” The entirety of the aforementioned application is incorporated by reference hereinTECHNICAL FIELD[0002]The subject invention relates generally to industrial control systems, and more particularly to a system and methodology that enables industrial automation equipment to be regulated according to applicable standards via the employment of electronic signatures, wherein operator actions requiring signature verification are queued pending outcome of a completed signature or cancellation thereof.BACKGROUND OF THE INVENTION[0003]Industrial controllers are special-purpose computers utilized for controlling industrial processes, manufacturing equipment, and other factory automation, such as data collection or networked systems. Controllers often work in concert with other computer...

Problems solved by technology

However, these signatures may be lacking several key features required under 21 CFR Part 11.

For example, the meanings of the signatures are not presented to the signers nor recorded, and in some electronic event journals it may be difficult or impossible to determine if an electronic signature was properly obtained or not.

In view of the above, many modern industrial automation systems are not equipped to process, record, and document required signature activities.

Attempting to manage such activities from various locations can be a challenge even for the most sophisticated of automation systems.

Moreover, current systems that may utilize some form of electronic process validation do not predicate such validation on the actual verification of a signature before continuing further system processing.
