Abstract
Re-certification of a control program loaded in a safety controller is avoided through the use of a digital snapshot and digital signature, the snapshot providing a rapidly loadable memory image file and the signature providing a confirmation that the file loaded matches a previously certified copy so as to avoid the need for time consuming re-certification.
