The invention relates to an apparatus for the generation of a program for a programmable logic controller having a programming input unit for the selection and compilation of a plurality of symbols, a generation unit for the generation of a program code for the programmable logic controller from an arrangement of symbols compiled at the display unit of the programming input unit. In accordance with the invention an investigation unit for investigating the resulting possible influences of input signals of the programmable logic controller, onto output signals of the programmable logic controller at the actuator outputs from the arrangement of symbols generated by the program code or compiled at the display unit of the programming input unit is provided. In accordance with the invention an implementing unit for implementing the possible exertion of influence in a matrix and a display unit for the display of the matrix are also provided. The invention further relates to a programming device for a programmable logic controller having such an apparatus for the generation of a program, a corresponding method for programming a programmable logic controller and a corresponding computer program product.

Programming programmable logic controllers using exertion influence in establishing matrix parameters

A safety controller () having at least one input () for the connection of a sensor (), at least one output () for the connection of an actuator (), at least one communication interface () for the connection of a further safety controller (-), to exchange control relevant information as well as having and also having a control unit () is provided which is configured to carry out a control program which generates a control signal at the outputs () in accordance with predeterminable logic rules in dependence on input signals at the inputs () and/or in dependence on the control relevant information. In this respect the communication interface () is configured for the connection of safety controllers (-) in a line arrangement, in which each safety controller (-) has a neighboring safety controller (-) arranged as a predecessor and/or a neighboring safety controller (-) arranged as a successor, and the logic rules process control relevant information of a connected predecessor and/or a connected successor and communicate the so determined control signals as control relevant information to a connected predecessor and/or a connected successor.
