Abstract: A safety switching apparatus for safe disconnection of an electrical load in an automated installation has at least one input for connecting a signaling device. The safety switching apparatus has an evaluation and control unit and at least one switching element controlled by the evaluation and control unit in order to interrupt an electrical power supply path to the load. The switching element is a changeover switch having at least two mutually alternative switching paths, with a first switching path being located in the electrical power supply path to the load and with a second switching path leading to a monitoring unit.

Abstract: The present invention describes a method of allocating a defined user address to a safe bus user when connecting it to a field bus of a safe control system. The method comprises the step of sending out a first registration message from the safe bus user to an administration unit connected to the field bus. The first registration message contains a predetermined universal address. The method further comprises the step of sending out an address allocation message from the administration unit to the safe bus user, wherein the address allocation message contains the defined user address. Finally, the method comprises the step of storing the defined user address in a memory of the safe bus user.

Abstract: An arrangement for controlling an automated system, having a number of sensors and actuators, in particular for controlling a railroad system. A programmable control unit runs a user program to process input data from the sensors and to generate control commands for the actuators. The sensors and the actuators are connected to a remote I/O unit, which is connected to the control unit via a communication network. The control unit and the I/O unit interchange data messages in order to transmit the input data and the control commands. The arrangement has a remote disconnection unit, which is coupled to the remote I/O unit independently from the input data and control commands. The control unit is designed to integrate specific verification data for the disconnection unit into the data messages for the I/O unit. The disconnection unit is designed to deactivate the I/O unit depending on the specific verification data.

Abstract: In a method for transmitting data in a control system, a first station generates a data frame having a plurality of data fields. At least one data field to be filled with transmission data is clearly assigned to each further station. The data frame is transmitted as an outgoing data frame from one station to the next, with every further station filling the respectively assigned data field with transmission data. The last station returns the data frame as a returning data frame to the series of stations. The stations read extraneous transmission data from the data fields in the returning data frame. Preferably, the respective data fields are individually assigned to the stations.

Abstract: The present invention relates to an apparatus for controlling safety-critical processes. The apparatus includes at least one safe control unit for controlling the safety-critical processes and at least two safe signal units which are connected via I/O channels to the safety-critical processes. The safe control unit and the safe signal units are connected to a common fieldbus. The safe signal units communicate with the safe control unit, but not with one another, when the apparatus is in the control mode. The safe signal units have an evaluator for evaluating a fault message which is broadcasted across the fieldbus, as well as a switching device which autonomously change the safety-critical process to a safe state when a fault message which is evaluated as being relevant occurs.

Abstract: The present invention relates to an electronic safety switching device having at least a first and a second signal processing channel. The channels can be supplied with input signals for signal processing, and they provide redundantly processed output signals. According to one aspect of the invention, the signal processing channels are arranged monolithically on a common semiconductor substrate. The semiconductor structures of each signal processing channel are spaced apart physically by a multiple of their width from the semiconductor structures of every other signal processing channel.
