How to Connect EtherNet/IP to Cloud SCADA

EtherNet/IP and Allen-Bradley

EtherNet/IP (built on the Common Industrial Protocol, CIP) is the native network for Rockwell Automation controllers. Reading a ControlLogix or CompactLogix over EtherNet/IP gives you the same tags the PLC exposes, which is why it is the direct path to monitor Allen-Bradley equipment. Merobix reads EtherNet/IP among its broad protocol-driver coverage.

Monitoring Without Touching Control

A monitoring platform only reads - it does not change the PLC logic. Merobix polls the EtherNet/IP device for the tags you select and presents them in the cloud, so your control program keeps running exactly as before. On mixed fleets, EtherNet/IP sits alongside Modbus, S7, and DNP3 in the same platform, so Allen-Bradley and non-Rockwell devices land in one dashboard.

How to Connect EtherNet/IP Devices to Merobix

1. Confirm the protocol and connection. Identify that your device speaks EtherNet/IP and how it is reached - a direct IP address, a serial connection, or through a cellular gateway at the site.
2. Establish connectivity to the cloud. For remote sites, a cellular edge gateway reads the local device and connects outbound to the cloud - no fixed IP, no inbound firewall rule, no VPN. On networked sites, a direct connection works.
3. Map the tags you care about. Select the registers, points, or nodes you want to monitor - pressures, levels, flows, states, alarms - and map them to named tags with engineering units. Merobix configures this for you as part of onboarding.
4. Set polling or report-by-exception. Choose how data is collected - scheduled polling for reliable links, or report-by-exception to conserve cellular data and battery on remote sites.
5. Verify data and set alarms. Confirm live values match the field, then set alarm thresholds. Sub-30-second SMS and email alarms are included, so the data is not just visible - it reaches someone when it matters.
