The Original New Schneider Electric BMXNOM0200 is a 2‑port serial link communication module for the Modicon X80 I/O platform, designed to enable robust serial connectivity between Modicon M340 and M580 Programmable Automation Controllers (PACs) and field devices such as drives, HMIs, barcode readers, weighing systems, and third‑party instrumentation. The module provides two independent serial channels configurable for RS232 or RS485 with support for both Modbus RTU (master or slave) and Character Mode protocols. It is installed in a standard X80 rack slot and powered via the backplane, making it a simple‑format, dedicated module for building serial communication links in industrial automation systems.
