The invention relates to a method for programming a safety controller, comprising the following steps: determination of logical connections between input signals on the safety controller and allocation of logical products (M4, M5) to output signals from the safety controller. The determination of the connections and the allocation is thus achieved by pre-defined function-specific program modules (62-72, 76-80), selected from a number (60) of such program modules. The invention is characterised in that each selected program module (76, 78, 70) is uniquely allocated to a defined function group (54, 56, 58). A first function group (54) comprises program modules (76) which accept input signals to the safety controller and produce first intermediate parameters (M1, M2, M3), based thereon. A second function group (56) comprises program modules (78) which logically connect the first intermediate parameters (M1, M2, M3) to each other and produce second intermediate parameters (M4, M5) based thereon. A third function group (58) comprises program modules (80), which allocate the second intermediate parameters (M4, M5) to the output signals of the safety controller. The invention further relates to a corresponding device and corresponding computer programs.
