Planar4 systems integrate inputs, logic processing and outputs on every module. The application-

specific programming of the systems is accomplished without software, instead using various wiring

techniques such as solder, Termipoint or Wire Wrap on the backplane bus board. All modules can

be used in a redundant structure in order to increase availability.
