A method and apparatus for monitoring a safety condition of a device, receive data from a plurality of operating-state detectors of the device selected on the basis of a specific configuration of the device to signal dangerous operating conditions of the device. Furthermore, to eliminate the need to completely redesign a safety monitoring program in response to modifications or expansions of the device, all the safety parameters are stored in one memory. The use of an exchangeable memory further simplifies modification of the system. A specific identifier is employed to rule out the use of an incorrect memory and a check sum for the memory contents allows detection of any unauthorized change in the memory contents.
