REDUNDANT AUTOMATION SYSTEM WITH A PLURALITY OF PROCESSING UNITS FOR EACH HARDWARE UNIT

The present invention relates to a plurality of hardware units (2, 3) of a redundant automation system, wherein each include a plurality of processor units (4, 7) that each execute a group of tasks, where groups of tasks (G1, G2, G3, G4) executed on different hardware units (2,3) receive the same input signals (E1, E2) directly or indirectly from a managed industrial process (1), and determine thesame output signals (A1, A2) for the managed industrial process (1), where however, only the tasks (G1, G2, G3, G4) of one of the groups executed on different hardware units (2, 3) each output theiroutput signals (A1, A2) to the managed industrial process (1), where the groups executed on different hardware units (2, 3) synchronize with one another via a respective communication link (14, 15), 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 (16, 17, 18, 19). 本发明涉及一种冗余的自动化系统的多个硬件单元(2、3)，它们分别包含多个处理器单元(4
