  • Patent number: 10996659
    Abstract: A plurality of hardware units of a redundant automation system each include a plurality of processor units that each execute a group of tasks, where groups of tasks executed on different hardware units receive the same input signals directly or indirectly from a managed industrial process, and determine the same output signals for the managed industrial process, where however, only the tasks of one of the groups executed on different hardware units each output their output signals to the managed industrial process, where the groups executed on different hardware units synchronize with one another via a respective communication link, and where the groups of tasks executed on the same hardware unit exchange data between themselves on a pair basis via a respective pair of intermediate storage units.

  • Publication number: 20200394111
    Abstract: A method for operating a redundantly configured automation system which has a first subsystem and a second subsystem, wherein one of these subsystems operates as the master and the other of these subsystems operates as the slave, where in the event that the master fails the slave takes over the function of the master, and where the first subsystem receives a data packet generated by an external data source and forwards the data packet only at a level of the physical layer and the data link layer to the second subsystem before processing of the data packet occurs in the first subsystem at a higher layer than the level of the physical layer and the data link layer.

  • Publication number: 20190302742
    Abstract: Method for setting up a redundant communication connection, and failsafe control unit, wherein a transport and/or switching functional unit of a communication device utilizes at least one communication network address associated with a primary control device and/or a secondary control device to set up two communication connections to a failsafe control unit that includes the primary control device and the secondary control device, where data transmitted via a first communication connection are forwarded from the primary control device to the secondary control device via a first synchronization connection such that data transmitted via a second communication connection are forwarded from the secondary control device to the primary control device via a second synchronization connection.

  • Patent number: 10365618
    Abstract: A method with which one subsystem of a redundant automation system that is provided with a first subsystem and a second subsystem is operated as a master and another subsystem is operated as a slave, where the subsystems are provided with transmission and reception tasks to transmit and receive messages, and where messages are also interchanged with program path synchronization during a temporally asynchronous run through a program path in the master and the slave.

  • Publication number: 20170351252
    Abstract: A method for operating a redundant automation system having a plurality of subsystems, wherein one subsystem of the plurality of subsystems operates as a master and assumes process control and the other subsystem operates as a reserve during redundant operation, where measures are provided by which the availability of the redundant automation system is increased, and where regardless of whether transient errors occur on the subsystem of the plurality of subsystems operating as the master or on the subsystem operating as the reserve, a total failure of the automation system is largely avoided.

  • Patent number: 9524259
    Abstract: A method for operating an automation device having a CPU module that is configured to effect read or write access to local peripherals that are each provided with two interface modules that are each wired up in ring form to an input/output controller, wherein peripheral access operations are executed via one of the rings or via both rings, and wherein a redundancy manager that is provided for each ring is used to logically interrupt the respective ring in a normal mode and to initiate ring reconfiguration for this ring in the event of a physical ring interruption so as to provide a basis for allowing peripheral access operations during the actual period of this ring reconfiguration.

  • Patent number: 9405644
    Abstract: A redundant automation system having a plurality of automation devices which are connected to one another comprises a plurality of master devices and a slave device. Each of the plurality of automation devices processes a control program in order to control a technical process. At least one of the plurality of automation devices operates as a slave and at least two of the plurality of automation devices, each operates as a master. The plurality of master devices is each configured to run a respective master program and to process processing sections of the respective master program of the respective master program, and the slave device is configured to process a corresponding slave control program for each master control program run by the plurality of master devices and, if one of the plurality of master devices fails, to assume the function of the failed master.

  • Patent number: 9389971
    Abstract: A redundant automation system and a method for operating the redundant automation system which is provided with a first subsystem and a second subsystem that each process a control program while controlling a technical process, one of these subsystems operating as a master and the other subsystem operating as a slave, and the slave assuming the function of the master if the master fails such that it becomes possible to dispense with temporally synchronous communication between the participants with regard to the synchronization of the program processing in the two subsystems, thus reducing the communication load.
