A head module for a modular control device includes redundant channel units, each including a processing unit and multiple failure revelation units. The head module includes a bus disconnection unit configured to shut down a communication bus. The failure revelation units are configured to monitor a state of the channel units. The processing units are configured to continuously stimulate the failure revelation units. At least one of the processing units is coupled to signal wires of the communication bus to provide a communication link to one or more peripheral modules of the modular control device. The failure revelation units are further configured to control, based on the stimulation and the monitoring, the bus disconnection unit.

A control device for controlling a technical installation includes a guard module. The control device has a modular structure with an input module, which receives an input signal representing a state of the technical installation, and an output module, which outputs an output signal controlling the technical installation based on the input signal. A guard module is integrated into the modular structure to monitor operability of the input module and the output module. The guard module confirms the output signal of the output module based on its monitoring of the input module and the output module. Within the modular structure, the input module and the output module form a first potential group. The guard module forms a second potential group within in the modular structure. The second potential group is independent of the first potential group.

A device for open-loop control or closed-loop control of a technical installation has a first backplane module, a second backplane module and a third backplane module which are configured to be positioned side by side on a mounting rail in a longitudinal direction. The first backplane module has a first main body and a first contact part. The second backplane module has a second main body and a second contact part. The third backplane module has a third main body and a third contact part. The main bodies each have an upper side comprising insertion openings which are configured to receive electrical contacts of separate electronic modules. The contact parts form a bus line in the longitudinal direction such that plugged-in electronic modules can be electrically coupled to one another by means of the contact parts. The second main body further has a receptacle, in which the second contact part is arranged in one of at least two defined variants. In a first variant, the second contact part has an electrically conductive connection to the first contact part and to the third contact part. In a second variant, the second contact part has an electrically conductive connection to the third contact part, but not to the first contact part.

A process data transmitter transmits process data at defined recurring time intervals as a serial transmit data stream including data symbols at a defined symbol rate. A process data receiver samples the serial transmit data stream at a sampling rate which is higher than the symbol rate by a defined factor to thereby generate a serial receiver data stream having a plurality of sampling values per data symbol. The process data receiver subdivides the serial receiver data stream into data packets, each of which has a defined first number of sampling values. The process data receiver selects a defined second number of sampling values from the respective data packets. The second number is smaller than the first number by the defined factor and the sampling values selected from each data packet are equidistant from one another. The process data receiver processes the selected sampling values as received process data.

Method and apparatus for transmitting process data in an automatically controlled installation

A control apparatus has at least one module including first, second and third module parts. The first and second module parts can be mechanically and electrically combined to form a first combined arrangement. The first and third module parts can be mechanically and electrically combined to form a second combined arrangement. The first module part comprises a securing element with an engagement section moveable between a first position, wherein the first and second module part are secured together, and a second position wherein the first and second module parts can be detached from one another. The securing element includes an actuation section. In the first position, the actuation section is located in a first spatial region and, in the second position, is located in a second spatial region. The third module part has a blocking section, which, in the second combined arrangement, occupies at least partially the second spatial region.

A safety circuit assembly for switching on or switching off a hazardous system in a failsafe manner has an evaluating device which is designed to produce a redundant switching signal. The evaluating device is connected to a signaling device via a first and a second line forming a pair of lines. The signaling device has an actuator which can be switched between a defined first state and at least one further state. The evaluating device produces a first defined pulse signal and transmits the first defined pulse signal to the signaling device using the pair of lines in a first direction. The signaling device produces a second defined pulse signal, which is a predefined replica of the first pulse signal, and transmits the second defined pulse signal to the evaluating device using the same pair of lines when the actuator is in the defined first state.

A control apparatus has a number of modules arranged next to one another in a longitudinal direction. The modules each comprise at least one module part having a housing. Furthermore, the module part comprises a first electrical bus connector on a first side of the housing for electrical connection to a first neighboring module part adjacent in the longitudinal direction, and a second electrical bus connector on a second side, opposite the first side, of the housing for electrical connection to a second neighboring module part adjacent in the longitudinal direction. The module part further comprises at least one movable element, movable between a first position and a second position. In the first position, the movable element provides an electrical connection between the first bus connector and the second bus connector and, in the second position, provides an insulation point between the first bus connector and the second bus connector.
