Abstract
The subject invention relates to a system and methodology facilitating automated manufacturing processes in a regulated industrial controller environment, wherein a centralized signature component generates signature events to remote locations and validates signatures required to satisfy such events. A system for distributed signature processing is provided. The system includes a signature component to determine when to generate one or more electronic signature events and to validate electronic signatures that have been received from various local or remote locations. An application layer distributes interface components to the locations in order to facilitate generation of the electronic signature events and validation of the electronic signatures.
