FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can B&R 7IF311.7 replace an RS485 interface module?
No. It provides RS232, which has different electrical signaling and topology from RS485 or RS422; match the installed device and wiring.
What communication settings must match on B&R 7IF311.7?
Confirm baud rate, data bits, parity, stop bits, handshake and the application protocol at both endpoints.
Why can B&R 7IF311.7 transmit but receive no data?
Check TX/RX crossover, signal ground, connector pinout, handshake lines, frame settings, cable condition and whether the external device is addressed or enabled.
Why can communication become unreliable after extending the cable connected to B&R 7IF311.7?
Check the cable length, baud rate, shielding, signal ground, routing and connector condition. B&R documents a distance of 15 m at 19.2 kbit/s; higher baud rates, electrical noise or unsuitable adapters can reduce the reliable distance.
What should be recorded before replacing B&R 7IF311.7?
Record the CPU slot, cable and pinout, remote device, communication parameters, handshake use, protocol settings and application function.
How should the RS232 cable for B&R 7IF311.7 be routed?
Follow the documented cable and grounding practice, keep it away from motor and switching conductors, and avoid unverified adapters that change the pinout.
What should be tested after installing B&R 7IF311.7?
Verify two-way data exchange, protocol framing, timeout and recovery behavior, diagnostics and the actual machine function that depends on the serial device.
