Modular automation system and method are disclosed. A central automation device can be constructed and upgraded using one of a plurality of selectable and variously upgradable baseboards. The automation device can be upgraded using one of a plurality of central units which have uniform external dimensions yet differing data processing power and data storage capacities. At least one input/output expansion device can be directly coupled onto the central unit. Each of the selectable baseboards has a field bus connection interface for a standard field bus connection to a decentral input/output unit.
