20130290776 | Redundant Automation System and Method for Operating the Redundant Automation System - 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. | 10-31-2013 |
20130318041 | Method for Operating a Redundant Automation System - A method for operating an automation system having at least two subsystems which are each provided with a control program, wherein relevant data from one subsystem is transmitted to the other subsystem within the scope of an updating phase of the automation system to transfer process control from a solo mode of one of the subsystems to a redundant control mode with another of the subsystems so as to facilitate updating. | 11-28-2013 |
20140058533 | Method for Operating a Redundant Automation System - A method for operating a redundant automation system provided with a first subsystem and a second subsystem, wherein one of the subsystems is operated as a master (M) and the other subsystem is operated as a slave (S), the subsystems (M, S) are provided with transmission and reception tasks to transmit and receive messages, and wherein messages are also interchanged with program path synchronization within the scope of a temporally asynchronous run through a program path in the master and the slave. | 02-27-2014 |
20140316578 | Method for Operating an Industrial controller and Industrial Controller - Regarding a method for operating an industrial controller, a control program executable in a processor that is arranged in the industrial controller is subdivided into a main block and several program blocks. The program blocks are processed under event control that takes a processing priority into consideration. The processor includes a multi-core processor having a plurality of independent sub-processors. The method includes assigning the main block to a first sub-processor, and executing a part program associated with the main block in the first sub-processor. The method also includes assigning each of the several program blocks to the additional sub-processors, and executing the part programs associated with the program blocks in the respective sub-processors. The method further includes operating a control device to evaluate as input variables the processing priority and an event assigned to the respective program block, and switching the sub-processors into active or inactive state using the evaluation. | 10-23-2014 |
20150095690 | Redundant Automation System - 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. | 04-02-2015 |
20150120013 | METHOD FOR REPRODUCING THE SEQUENCE OF A PROGRAM IN AN AUTOMATION DEVICE - A method for reproducing the sequence of a program provided for process control in an automation device, wherein a program that corresponds to the program in the automation device with regard to process control is provided for processing using a backup device, where suitable measures can be used to image the complete history of the automation device and to reproduce the sequence of the program so that with regard to the processing of the program, it becomes possible to subsequently and repeatedly approach any desired time in the past and to reproduce all associated data. | 04-30-2015 |
20150134082 | METHOD FOR OPERATING AN AUTOMATION SYSTEM - A method for operating an automation system provided with a first subsystem and a second subsystem which each process a control program in order to control a technical process, one of these subsystems operating as a master and the other subsystem operating as a slave, wherein measures are provided which make it possible to provide diagnostic and/or test data for diagnostic and/or test measures during control operation, in which case it is not necessary to dispense with a breakpoint function. | 05-14-2015 |
20150154130 | METHOD FOR OPERATING AN AUTOMATION DEVICE - 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. | 06-04-2015 |
