A printing press programmable logic conversion apparatus and method involves the replacement of a series of OEM relay logic printed circuit boards with a single programmable logic controller or PLC. The PLC is connected into a rack which includes a plurality of male edge connectors attached together and spaced apart to replace the OEM PC boards. The PLC is preprogrammed to emulate the replaced OEM PC boards such that, by removing the OEM PC boards and simply plugging in the PLC rack in their place, an older press can be converted to PLC control within a matter of minutes.
