Abstract
An expandable automation system includes both a programmable controller that is capable of stand-alone operation, and a modular programmable controller. The programmable controller that is capable of standalone operation has an interface, such as a multipole plug connector, for connecting expansion units. The modular programmable controller consists of a central processing unit and expansion modules. The expansion modules of the modular programmable controller can be used as expansion units for the programmable controller that is capable of standalone operation.
