Safety Signature Match

FactoryTalk® Design Studio™

validates the safety signature within the safety target controller against known

FactoryTalk® Design Studio™

-issued safety signatures.

When a mismatch of safety signatures occurs, a warning shows that an internal error has occurred that requires you to delete the safety signature. You can either delete and regenerate the safety signature before deployment, or acknowledge the warning, deploy the safety application (which deletes the safety signature), then regenerate the safety signature.
