Function and Positioning

This module serves as a key multi‑serial communication expansion component for B&R industrial control systems. It establishes reliable serial data links between the main controller and field devices via RS232 and dual RS485/RS422 ports. It supports point‑to‑point and multi‑drop network topologies, enabling connection with serial‑based HMIs, printers, scanners, sensors, and third‑party controllers. The independent galvanic isolation per channel eliminates cross‑interference and common‑mode voltage risks, ensuring stable communication in noisy industrial sites. It reduces the main CPU’s communication burden and improves system networking flexibility.
