Abstract
An I/O device is configured to couple a plurality of process control field devices to a process controller controlling a process in an industrial process plant. The I/O device includes a backplane and a plurality of electronic marshalling component (EMC) slots. The EMC slots are each configured to receive a respective EMC and to receive either of (i) a first-type EMC associated with a first communication protocol or (ii) second-type EMC associated with a second communication protocol. The I/O device also includes I/O processor module slots, each communicatively coupled, via the backplane, to each of the EMC slots and to each of a first one or more connectors and a second one or more connectors in each of the EMC slots. The I/O device further includes communication ports, each communicatively coupled to the I/O processor module slots via the backplane.
