Remote IO — Beijer Electronics Connection

Overview

System setup — SMX-RNS20 reading Modbus TCP data directly from Beijer modules (no PLC required)

Beijer Electronics controllers (X2, E-series) support Modbus TCP as a standard communication protocol. Use the SMX-RNS20’s Modbus TCP driver to read coils, discrete inputs, holding registers, and input registers from any Beijer controller that exposes a Modbus TCP server.

For the Beijer NA-9289 adapter, refer to the dedicated manual available in the Downloads section.

Beijer Controller Configuration

• In EXOR / Beijer MAKE (or your applicable IDE), enable the Modbus TCP Server on the controller’s Ethernet port.
• Set a static IP address on the same subnet as the SMX-RNS20 LAN port.
• Note the Modbus TCP port (default: 502) and the addresses of registers you want to read.

SMX-RNS20 Remote IO Configuration

1. Log in to the SMX-RNS20 web interface and navigate to Remote IO → Connections.
2. Click Add Connection and select Driver: Modbus TCP.
3. Enter the Beijer controller’s IP address and port (default 502). Set the Unit ID (Slave ID), usually 1.
4. Add data points: select Function code (FC01 coils, FC02 discrete inputs, FC03 holding registers, FC04 input registers), set the start address and quantity.
5. Save the configuration. The SMX-RNS20 will start polling the Beijer controller at the configured interval.
