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).

Abstract: A modular safety device (10) is set forth for the safe deactivation of actuators (22, 24) which form a hazard source, said safety device having a control module (12) with a central safety controller (26), at least one connector module (14) of a first type with inputs for the connection of sensors (18, 20) and outputs for the connection of actuators (22, 24) as well as a serial communications device (28) for the exchange of data between the control module (12) and the connector module (14) based on a first communications protocol, in particular a bus.

Abstract: The invention relates to a control system, in particular to a safety control system, comprising at least one sensor, at least one control module for the reading out of the at least one sensor and for the generation of a control signal, wherein the at least one control module has at least one connection for a cable which can be connected to the control module. The control system in accordance with the invention furthermore has a data memory module which is mechanically connected to the cable to be connected to the connection and a data memory unit for the storage of configuration data of the control. A communications path is provided for the transfer of configuration data between the at east one control module and the at least one data memory module, wherein the cable is not provided, or is not only provided, for the data transfer between the data memory unit of the at least one data memory module and the at least one control module.

Abstract: A coupling apparatus is described for the connection of devices such as sensors, actuators, contact free protection devices (electro-sensitive protection equipment ESPE), light barriers or controls to a bus system. The coupling apparatus includes at least one connection unit at the bus side for the connection of the coupling apparatus to the bus system and at least one connection unit at the device side for the connection of a device to the coupling apparatus. The connection unit at the device side includes n (n>1) contact elements of which each has one pre-defined functional property from a set of m (m>1) pre-defined functional properties. At least some of the contact elements are designed as variable contact elements to each of which one of the pre-defined functional properties can be variably assigned.
