Abstract
A method and an engineering system that reduce the configuration complexity with regard to a possible expansion of the automation device are provided. The automation device includes slave units and a master unit (7, 15) connected to the slave units via a bus. The slave units include one or more slave units (11, 12, 16, 17) and one or more reserve slave units (13, 18). The configuration of a reserve slave unit (13, 18) enables the master access time interval (20) and the slave access time intervals (21, 22, 23) to be expanded for a possible expansion of the automation device. As a result, a configured automation device of this type can be expanded by an additional slave unit without additional configuration or reconfiguration.
