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.
Claims12
