Method for operating a redundantly configured automation system which includes has a first subsystem, a second subsystem and a third subsystem, wherein a sequence program is implemented in each of the subsystems of the automation system and is executable in a runtime environment to fulfill automation tasks, and wherein a data memory is implemented in the subsystems in each of the automation systems, where the sequence program includes at least a first subprogram and a second subprogram, the data memory in each of the subsystems includes at least a first submemory and a second submemory, the first subprogram and the first submemory are synchronized with a first synchronization clock between the first and second subsystems, and the second subprogram and the second submemory are synchronized with a second synchronization clock between the first and third subsystems, and where the first and synchronization clocks differ from one another.

Redundantly configured automation system and method using three subsystems

An automated method determines a safety zone for a robot. The robot carries out operations along a specified trajectory. For collision-free operation, a safety zone is determined by: dividing the specified trajectory into a plurality of subtrajectories; determining a plurality of fine-grained envelope cuboids around extreme points of each subtrajectory; and determining a number of optimized envelope cuboids from an enlargement of individual fine-grained envelope cuboids in relation to the volume occupied by the enlarged fine-grained envelope cuboids. The optimized envelope cuboids determined in this way form the safety zone for the trajectory. This automated method can be expanded to multiple trajectories of a robot, multiple robots, and replanning a trajectory for an occupied semaphore zone.

A real-time automation device includes a real-time databus, and a memory device, wherein the databus is configured to transmit values associated with defined bus variables and configured to communicate a value associated with a bus variable from a bus variable source in accordance with a bus database via a databus to a bus variable receiver associated with the bus variable in accordance with the bus database such that, following transfer of the value from the bus variable source to the databus, the value is transferred within a predefined time period to the bus variable receiver, wherein the memory device also includes a software application which receives values associated with the bus variable from the databus or sends values associated with the bus variable to the databus, and wherein the automation device registers the software application as a bus variable receiver or as a bus variable source for the bus variables.

A method for operating a programmable logic control device to which a current input data set having state data regarding a peripheral component is provided cyclically by a communications bus after each bus cycle terminates. A first program instance of a control program is cyclically processed by a control device. The program cycle duration is longer than the bus cycle duration and, therefore, between the beginning and end of the program cycle, the communications bus provides at least one current data set that cannot be taken into account by the first program instance. To reduce the latency with which a control device reacts to a change in the input value of a peripheral component. at least one other program instance of the control program is cyclically processed so that it is temporally offset by less than one program cycle duration relative to the first program instance.

Method for anticipatory regulation of energy flows in an electrical supply grid of an automation installation, which includes a number of connecting devices that are connected to the electrical supply grid, wherein the connecting devices exchange information with respect to their energy requirements or their energy supply among one another and the connecting devices exchange energy among one another based on the information.

Decentralized energy management in automated industrial installations using self-organizing networks

A method for operating a multi-core processor system, wherein different of a program are each executed simultaneously by a different respective processor core of the multi-core processor system includes inserting a breakpoint in a first of the threads for interrupting the first processor core and instead executing an exception handling routine. At least one processor core to be additionally interrupted is determined with the exception handling routine on the basis of an association matrix, and an inter-processor interrupt (IPI) is sent to the at least one processor core by the exception handling routine in order to interrupt the at least one processor core.

Multicore processor system having an error analysis function

A method for regulating process, production, and/or actuating installation includes recording observation data records at installation components of the installation by respective recording units of the installation. The method also includes transmitting the observation data records to a central control apparatus of the installation via a field bus. The method further includes forming, at the control apparatus, associated actuating data record based on the transmitted observation data records. The method also includes transmitting the actuating data records to actuating units of the installation via filed buses. The method also includes adjusting the installation components from the actuating units based on the transmitted actuating data records. The observation data records are encrypted at the respective recording units before transmitted to the control apparatus The actuating data records are formed from the encrypted observation data records without decrypting the encrypted observation data records during the process of forming the actuating data records.

Tamperproof regulation of a process, production, and actuating installation

An industrial robot with a robotic arm and a data recording module connected to the robotic arm is described. The data recording module is designed for a wireless communication and has a self-sufficient power supply with a converter unit by which mechanical energy is converted into electrical energy, the energy from the movement of the robotic arm being used therefore.
