A method for creating a user program for a safety controller designed to control an automated installation having a plurality of sensors and a plurality of actuators involves several programming steps. The user program comprises a first program portion, in which safety-related program variables are processed in failsafe fashion, and comprises at least one second program portion, in which non-safety-related program variables are processed, wherein failsafe processing is not necessary for the non-safety-related program variables within the second program portion. The method steps involve a step of defining a number of safety-related program variables, a step of defining a number of non-safety-related program variables, a step of selecting a safety-related program variable from the number of safety-related program variables, a step of selecting a first non-safety-related program variable from the number of non-safety-related program variables, wherein the first non-safety-related program variable is repeatedly assigned an instantaneous value when the user program is executed, a step of defining at least one assignment condition which is processed when the user program is executed, a step of defining an association which associates the selected first non-safety-related program variable with the selected safety-related program variable, wherein the instantaneous value of the selected first non-safety-related program variable is assigned to the selected safety-related program variable depending on the assignment condition, when the user program is executed.

The present invention describes a method for configuring a station connected to a field bus, wherein a logical address is allocated to said station. The method comprises the steps of: transmitting said logical address from an address-allocation unit to said station; transmitting a physical address from said address-allocation unit to said station, said physical address corresponding to an assumed physical position of said station relative to said field bus; verifying said physical address being transmitted to said station based on an actual physical position of said station relative to said field bus; and storing said transmitted logical address in a memory of said station depending on the verification of said physical address.

The present invention describes a control system for controlling safety-critical processes. The control system has a first control unit for controlling a safety-critical process and at least one signal unit linked to the safety-critical process via I/O channels. It further comprises a field bus connecting said first control unit and said signal unit, and a bus master for controlling communication on said field bus. Said first control unit and said signal unit each comprise safety-directed arrangements for ensuring failsafe communication among each other. Said bus master is connected to said field bus separately from said first control unit and said signal unit.
