Configured for Ethernet remote input/output data collection and deterministic routing in Modicon M580 and M340 networks, the Schneider Electric BMXCRA31210 (BMXCRA31210 Ethernet Remote IO Drop Adaptor) provides direct physical/electrical execution. The module gathers input data from local X80 modules, publishes it to the remote I/O head adapter, and updates output modules via three RJ45 communication ports operating at 10/100 Mbit/s over IPv4 network topologies.

This module executes real-time data transmission across EtherNet/IP deterministic networks utilizing a Rapid Spanning Tree Protocol (RSTP) ring topology. The internal hardware processes up to 1024 discrete channels and 256 analog channels with fixed 10 ms time-stamping intervals. Network routing and determinism are sustained through dual dedicated RIO ports alongside a single insulated service port configuration, preventing message collision and ensuring uniform backplane bus throughput to the connected PAC.
Q: Does the module support Configuration Change On the Fly (CCOTF)?
A: Yes, the hardware architecture permits configuration modifications and module extensions during active runtime execution without interrupting the existing backplane bus state.
Q: What is the designated power source for this adaptor?
A: The module operates on an internal current draw of 1200 mA at a regulated input voltage of 3.3 VDC derived directly from the Modicon X80 rack backplane.
