ABSTRACT:
An update method is described for a supplementary automation system, which is to be coupled to a starting automation system, where the starting automation system controls a technical system. In the present invention, updating takes place free of update-interruption as opposed to interrupting program execution by the starting automation system, performing the updating and resuming program execution by both automation systems. In one embodiment, a non-time-critical system state is awaited and then updating is performed. In a second embodiment, the updating is interspersed in small time slices into the program execution.
