1. A method for the programming of a safety controller to be interconnected with encoders and actuators, comprising the steps of: preparing a wiring plan wherein the safety controller is shown with its connection terminals at least schematically on a graphic programming interface, said wiring plan preparation comprising: selecting the encoders and actuators with reference to encoder symbols and actuator symbols; andshowing wiring symbols on the programming interface which connect connection terminals of the encoder symbols and connection terminals of the actuator symbols to the connection terminals of the safety controller;configuring or preparing a program such that program parts are automatically activated or compiled which are provided for the evaluation of the selected encoders and for the control of the selected actuators; andautomatically associating parameters with these program parts which correspond to the connection terminals with which the respective encoder symbols and actuator symbols are associated. 2. A method in accordance with claim 1, wherein relative positions of each of the connection terminals shown on the graphic programming interface correspond to actual physical relative positions of each of the connection terminals. 3. A method in accordance with claim 1, wherein a physical model of the safety controller and the connection terminals of the safety controller is shown on the graphic programming interface. 4. A method in accordance with claim 1, wherein: a set of available encoder symbols and actuator symbols is shown on the programming interface; andat least one encoder symbol and at least one actuator symbol is selected from the set. 5. A method in accordance with claim 1, wherein the wiring symbols are automatically shown on the programming interface after selection of the encoder symbols and actuator symbols has taken place. 6. A method in accordance with claim 1, wherein the shown connection terminals of the safety controller are associated with a plurality of units physically separate from one another on the safety controller. 7. A method in accordance with claim 1, further comprising: printing out or displaying the wiring plan after the preparing of the wiring plan, with each of the connection terminals of the safety controller, encoders and actuators being shown, in each case according to their physical arrangement, including the connections between these connection terminals. 8. A method in accordance with claim 1, wherein an encoder-specific or an actuator specific element description is associated with each encoder and with each actuator in the form of a data set, said element description defining properties of the respective encoder or actuator. 9. A method in accordance with claim 8, wherein a program part is activated in dependence on the element description and evaluates or controls the respective encoder or actuator. 10. A method in accordance with claim 8, wherein parameters are derived from the element description which configure a program part which evaluates the respective encoder or controls the respective actuator. 11. A method in accordance with claim 8, wherein the element descriptions are stored in a programming device; or in that the element descriptions are stored in the associated encoders and actuators from where they are transferred to a programming device for programming purposes. 12. A method in accordance with claim 8, wherein the element description of the encoders includes at least one of the encoder-specific pieces of information named in the following: Number of the channels to be evaluated;Demands on the input terminals of the safety controller to be connected;Type of the evaluation (equivalent/ambivalent);Test configuration;Present connection terminals;Physical arrangement of the connection terminals; andEncoder marking. 13. A method in accordance with claim 12, wherein information from the Test Configuration lays down how many and which output connection terminal or terminals of the safety controller the encoder has to be wired with. 14. A method in accordance with claim 8, wherein the element description of the actuators includes at least one of the actuator-specific pieces of information named in the following: Number of the channels to be evaluated;Demands on the output terminals of the safety controller to be connected;Type of the control (equivalent/ambivalent);Present connection terminals;Physical arrangement of the connection terminals; andActuator marking. 15. A method in accordance with claim 1, wherein parameters are associated with activated or configured program parts which correspond to those connection terminals of the safety controller to which the respective encoder or actuator is connected. 16. A method in accordance with claim 1, further comprising the step of forming a data set having a description which defines properties of a respective encoder or actuator associated with at least one safety controller. 17. A method in accordance with claim 16, wherein a configuration of an encoder or of an actuator is carried out on the basis of the element description of a module in dependence on properties of the module. 18. A method in accordance with claim 1, wherein a program tool is deposited in a memory of the safety controller and is loaded into a programming device selected from the group consisting of a PC, a laptop and a handheld, before starting the programming.
