Main Features and Advantages
Dual CAN Channels with Full Isolation: The B&R 3IF672.9 features two independent CAN interfaces, each electrically isolated from the PLC bus and from each other. This isolation architecture prevents fault propagation between network segments, ensuring that a disturbance on one CAN channel cannot affect the other or the host controller. The CAN controller (82527 type) supports standard CAN protocols with external bus termination wiring options .
Flexible RS232 Serial Interface: The B&R 3IF672.9 provides a 9-pin DSUB RS232 port based on the ST16C650 UART controller with 32-byte FIFO buffers for both transmission and reception. Supporting data rates up to 115.2 kBit/s and configurable data formats (5-8 data bits, parity options, 1-2 stop bits), this interface accommodates a wide range of serial devices including programming terminals, modems, and legacy peripherals. The RS232 port can also serve as an online interface for system configuration and diagnostics .
Network-Capable CAN Architecture: The B&R 3IF672.9 supports network-capable CAN operation, allowing multiple modules and devices to communicate across a shared bus topology. With maximum transmission distances of up to 1000 meters at reduced baud rates, the module enables distributed control architectures in large industrial facilities. Status LEDs for each interface provide immediate visual feedback on data transmission activity, simplifying troubleshooting and commissioning .
Seamless System 2005 Integration: Designed specifically for B&R System 2005, the B&R 3IF672.9 inserts directly into interface module slots without requiring external adapters or additional mounting hardware. This plug-in design preserves rack space and maintains the compact footprint of the host CPU or interface unit .
