Abstract

In order to operate a safety control in an automation network having a master subscriber which implements the safety control, the safety control is assigned an identifier. When loading the safety control, the master subscriber checks whether the stored identifier in the safety master subscriber matches the identifier calculated form the safety control, and the automation network changes to a safe state if it is determined that the identifier differs.
