Remote Virtual LAN

– PLC Remote Upload & Download –

With Virtual Ethernet and Virtual Serial Port, engineers can remotely access PLCs, HMIs, and serial devices for programming, maintenance, and debugging as if they were on the same local network.

Drag & Drop Programming

– Low-code visual programming –

Using Node-RED visual programming, the EG8200Mini-104 gateway allows users to build automation workflows through drag-and-drop configuration. It supports integration with sensors and third-party platforms via protocols such as MQTT and JSON.

PREGUNTAS FRECUENTES

Q1: What network options does the EG8200Mini-104 edge IEC 104 Gateway support? How can I use it in a substation without Ethernet?

A: EG8200Mini-104 IEC 104 Gateway offers very flexible networking options, fitting a variety of industrial site scenarios:

• • Wired (RJ45): Connect via the Gigabit WAN port or 100Mbps LAN port to your local network.

  • Wi-Fi: Supports dual-band Wi-Fi (2.4GHz & 5GHz) as a client to connect to existing wireless networks.

  • Cellular (4G LTE): Built-in 4G Cat.1 module—just insert a SIM card, and your gateway can send data over the mobile network.

So even in older substations with no network cables, you can still use 4G to reliably send data back to the control center.

Q2: How do I use the EG8200Mini-104 IEC 104 Gateway to read substation digital and analog data? Is it complicated?

A: Configuration is straightforward using the visual Nodo-RED tool—no coding required. Here’s the core workflow:

1. Network setup: Ensure the gateway is on the same network as your substation devices (e.g., protection relays). You can adjust the LAN IP via the management interface.

2. Add nodes: In Node-RED, drag an IEC104 Client node from the left palette into your workflow.

3. Configure connections and points:

• • • In the node settings, enter the remote 104 slave’s IP address and port (default is 2404).

    • Digital inputs (DI/status points): Go to the “Digital” tab, add the points using the slave’s point addresses (like 1, 2), and assign names.

    • Analog inputs (AI/measurements): Go to the “Analog” tab, add the points with the corresponding addresses (like 16385, 16386) and names.

• 1. 4. Deploy & verify: Once deployed, the gateway will automatically read data at the configured intervals. You can monitor real-time values in the debug panel.
