Operating at selectable baud rates up to 500 kbps, the scanner manages cyclical, polled, strobe, and Change-of-State (COS) messaging protocols to minimize network bandwidth usage. Integrated backplane interface circuits exchange input\/output image tables directly with SLC 5\/03, 5\/04, or 5\/05 processors at maximum backplane bus communication velocity. Onboard logic provides transparent network pass-through execution, allowing programming software to configure downstream field devices across the SLC backplane without disconnecting physical network nodes.
