1. A switch fabric for an industrial control system, the switch fabric comprising:
a serial communications interface for connecting a plurality of slave devices to a master device in parallel, the serial communications interface configured for transmitting information between the plurality of slave devices and the master device;
a parallel communications interface for separately connecting the plurality of slave devices to the master device, the parallel communications interface configured for simultaneously transmitting information between the plurality of slave devices and the master device, and transmitting information between individual ones of the plurality of slave devices; and
a support frame to facilitate interconnection of the plurality of slave devices and the master device, the support frame comprising a plurality of slots, each slot of the plurality of slots for receiving a respective one of the plurality of slave devices, each slot of the plurality of slots associated with a unique identification, wherein, when a slave device is coupled with the support frame at a respective slot and identifies itself to the master device using a unique identification, the unique identification of the slave device is associated with the respective slot.
