## Question

How do Roll-2-Roll sensors connect to my PLC or industrial network?

## Short Answer

1DC sensors connect directly via EtherNet/IP, PROFINET, EtherCAT, Modbus/TCP, or CC-Link IE Field Basic. ODC sensors connect through SCU5 or SCU6x controllers with the same protocol options.

## Detailed Answer

Roll-2-Roll® sensors offer two integration paths, both providing real-time edge positions, width measurements, and inspection alerts to your PLC without middleware or custom drivers.

### 1DC Sensors — Direct PLC Connection

The 1DC has a built-in controller with an M8 4-pin network connector. It connects directly to your industrial Ethernet network via:

- EtherNet/IP
- PROFINET
- EtherCAT
- Modbus/TCP
- CC-Link IE Field Basic

This makes the 1DC ideal for OEMs and integrators who want a single-device solution with direct PLC communication.

### ODC Sensors — Via SCU5 or SCU6x Controller

ODC sensors connect to an SCU5 or SCU6x controller via M12 12-pin Quick Disconnect Sensor Cable (up to 10 m). The controller then provides the network interface:

- SCU6x — dual industrial Ethernet ports, 4 digital inputs (NPN/PNP/dry contact), 3 digital outputs, plus web browser dashboard for remote diagnostics
- SCU5 — single Ethernet port (EtherNet/IP, PROFINET, or EtherCAT depending on variant) plus analog outputs (±10V, 0–20 mA)

Both paths deliver edge positions, width data, and inspection signals — including splice alerts, flag detection triggers, and defect notifications — directly to Rockwell, Siemens, Beckhoff, or any EtherNet/IP-compatible PLC.
