Installation Guide

1. Install the BMXNOC0401 in any standard slot of the Modicon X80 rack
2. Connect Ethernet devices to the four RJ45 ports using shielded CAT5e or higher cable
3. For daisy chain: connect downstream devices to available ports
4. For ring topology: close the loop by connecting the last device back to the module
5. Configure IP addresses and protocol settings in EcoStruxure Control Expert
6. Verify port link LEDs indicate proper connection and data activity

Selection Tips

• Choose BMXNOC0401 when four Ethernet ports are required in a single X80 slot
• For single-port Modbus TCP, consider BMXNOE0100
• For FactoryCast web server functionality, evaluate BMXNOE0110
• Verify target devices support EtherNet/IP or Modbus TCP as required
• Plan cable routing to leverage daisy chain or ring topology for cost savings
