Product pictures

Product Overview: B&R 7IF321.7

Parameter Specification
Manufacturer B&R Industrial Automation
Model 7IF321.7
Product Series 2003 Series PLC System
Device Type Serial communication interface module
Interface Type 1× RS485 / RS422 serial port

Application & Fault Scenarios

Typical Uses: Adds RS485/RS422 serial communication capability to B&R 2003 Series PLC systems. Connects to serial devices such as barcode scanners, weighing scales, temperature controllers, and third-party PLCs for data exchange. Software-configurable between RS485 and RS422 modes.
Common Field Issues:
  • No communication established → verify RS485/RS422 wiring polarity (A/B or TX+/TX-); confirm baud rate, parity, and stop bit settings match the connected device; check if termination resistor is required for long cable runs.
  • Intermittent data errors → check for ground loop issues; verify cable shielding is properly grounded at one end only; ensure RS485 bus does not exceed maximum node count (typically 32 devices without repeater).
Note: The 7IF321.7 is part of B&R's 2003 Series modular PLC family. It requires a compatible 2003 Series backplane (e.g., 7BP701.0, 7BP702.0) for installation. Configuration is done via B&R Automation Studio software.
