Function and Positioning

The B&R 3IF672.9 acts as a versatile and cost-effective communication hub for mid-range industrial automation systems. It provides one RS232 port for point-to-point connections with HMIs, scanners, printers, or legacy serial devices, and two electrically isolated CAN interfaces for CANopen or CAN 2.0 network communication. It facilitates reliable data exchange between PLCs, servo drives, sensors, and distributed I/O modules. With hot-swappable capability and a compact design, it simplifies installation, maintenance, and system upgrades without halting entire production lines.
