Audit trail in a programmable safety instrumented system via biometric signature(s)
First Claim
1. A safety audit system that facilitates recording configuration changes to a manufacturing system, comprising:
- an identification component with a biometric sensor to sense and record biometric data for a user; and
a safety system component that tracks a configuration change(s) performed on the manufacturing system associated therewith.

Abstract
System(s) and method(s) that facilitate utilizing biometric sensors (e.g., fingerprint, hand scan, voice recognition . . . ) in manufacturing systems in order to maintain accurate safety audit trails. A safety audit system, utilizing a biometric sensing device, facilitates determining if a user is allowed to access and change the configuration of the manufacturing system. Once a user is allowed to change the configuration (e.g., programmable electronics, tooling changes, software updates, etc.) the changes are automatically recorded in a safety audit database. Automatic storage of configuration changes mitigates manual recording of changes thereby enhancing the safety audit data often necessary to meet safety standards for manufacturing systems.
