Abstract

A programmable logic controller is disclosed which comprises a router having a router backplane which is connected to the programmable logic controller. The router backplane is further connected to a plurality of network ports. The programmable logic controller or network port communicates the network message to the router and the router communicates the network message only to the programmable logic controller or the network port for which the network message is intended.
