| 摘要 |
The invention relates to a system (10) having at least two physically redundant controllers (22, 24, 48, 50) which is provided for applications that need to be continuously operable in spite of hardware faults, maintenance or replacement achieving high availability and/or functional safety and having at least one control unit (22) which is actively participating in the control loop and n redundant units (24) that are kept synchronized in stand-by, whereas . the execution of the software is replicated among the controllers (22, 24, 48, 50); . the controllers (22, 24, 48, 50) referred herein are any kind of stored program control computer used for discrete automation and motion, process and power systems automation inter alia; and . the controllers (22, 24, 48, 50) are being equipped with central processing units (CPUs) (38) featuring a plurality of cores (40, 42) organized within a single piece of silicon, being already known as multi-/manycore processors (36). Furthermore the invention relates to a method for operating the system appropriately. |
