  • Publication number: 20110098830
    Abstract: A safety controller (10) is set forth having at least one input (18) for the connection of a sensor (20), at least one output (22) for the connection of an actuator (24), at least one communications interface (30) for the connection of a further safety controller (10a-d) to exchange control-relevant information and having a control unit (14) which is made to carry out a control program which generates a control signal with reference to presettable logic rules at the outputs (22) in dependence on input signals at the inputs (18) and/or in dependence on the control-relevant information. In this respect, the control program, when it determines that an expected safety controller (10a-d) is not connected, uses predefined information instead of the safety-relevant information to be transferred from the expected safety controller (10a-d).
