Abstract
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.
