ABSTRACT:
A passive programmed array is provided for each printed circuit board of a control system. The passive programmed array provides the logic connectors for the circuit elements mounted upon the printed circuit board, and includes an electronic key to ensure that output from a particular printed circuit board will be enabled only when the appropriate passive programmed array is connected.
