How to Connect IEC 60870-5-104 to Cloud SCADA

IEC 60870-5-104 in Telemetry

IEC 104 is the network (TCP/IP) profile of the IEC 60870-5 telemetry standard, widely used for power utility and pipeline remote monitoring. Like DNP3, it timestamps events and supports spontaneous (report-by-exception) transmission, which suits wide-area telemetry with many remote stations.

Bringing IEC 104 Into the Cloud

Merobix supports IEC 60870-5-104 among its drivers, so devices and RTUs speaking IEC 104 can be read into the managed cloud, in parallel with a legacy host if needed. For sites with mixed telemetry protocols, IEC 104 sits alongside DNP3 and Modbus in one platform, so the whole network reports to a single web dashboard.

How to Connect IEC 60870-5-104 Devices to Merobix

1. Confirm the protocol and connection. Identify that your device speaks IEC 60870-5-104 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.
