Automation system for use in automation technology has a redundant central unit comprising two identical central units that are synchronized so that they execute the same programs and commands in a synchronized manner
Central unit comprises first (1) and second (1') central units linked together. The linking of the units is such that when a task (2, 3) executes in the first unit corresponding tasks (2', 3') are synchronously executed in the second unit. A synchronization unit (4) generates internal synchronization signals for the first central unit and external signals for the second unit. A task scheduler (10) will only authorize a task to run when both internal and external synchronization signals have been activated.
