Overview
The 140CRP31200C is a Schneider Modicon Quantum Ethernet RIO head module with conformal coating, wired as a daisy chain loop and speaking Ethernet IP/Modbus TCP across its four ports. It is discontinued as of 2022-03-30, so new builds should move to the active 140NOC78000C, which adds redundant ring topology and an embedded web server while keeping the same protocol and IP20 enclosure.
