Abstract

For the purpose of controlling safety functions as part of a system controller which is not oriented to safety functions in an automation system, the invention provides safety modules having a sound functionality and provides a safety protocol which transmits data in the form of safety messages, wherein input and output parameters from each safety module are encapsulated by the safety protocol, and the individual safety modules are logically combined with one another in terms of data and flow by means of a data transmission link in line with the system's safety functions which are to be controlled, the data interchange taking place between the safety modules on the basis of the safety protocol.
