Abstract

An electric control device generates control signals that control electrical devices. The control device has a multiplicity of control modules. At least some of the control modules have a comparator for comparing two values and they function in dependence on the various outcomes of comparison. One of more global comparators are provided for certain comparisons in the control device. Each of the global comparators operates on several or all of the control modules. The control modules operate not only in dependence on the comparisons in their respective comparators, but additionally in dependence on the comparison results in the global comparator.
