How MultiNode works

MultiNode LAN 4TE is a DIN-rail device that uses powerline communication (PLC) to send data over low-voltage mains.
Master node: The central controller of the network.
Regular nodes: They connect to the master through PLC. A regular node can automatically switch to a repeater role if needed.
Isolation: Regular nodes talk only to the master, not to each other.
Application devices (e.g., a charging station) connected to a regular node can only reach application devices connected to the master. Devices on diﬀerent regular nodes cannot connect directly.
The master node has a built-in web interface for setup and management; no extra tools are needed.

Step-by-step instructions

Plan your network
- Power supply considerations: Each power rail needs a circuit breaker. You can use one breaker for both the charging station and MultiNode, or separate breakers. MultiNode is powered by L1/N, e.g., from the charging infrastructure’s mains circuit.
- Distance: Large networks may need repeaters. The best range is up to 50 m per hop. 50–100 m may work, but over 100 m is not recommended.
- Circuits: One three-phase circuit for all devices gives the best results. Multiple circuits cause signal loss and noise. This can be solved with repeaters or by splitting networks via Ethernet.
- Topology: The network self-organizes into a tree: the master node is at the root, with regular nodes automatically acting as repeaters when needed.
- Master node placement: Place it where Ethernet is easy to reach, and signal paths are short. It is strongly recommended not to place it in the distribution unit.
- Load management in EV charging scenarios: Since regular nodes connect only to the master, EV charging scenarios need careful upfront planning. For guidance, see the user manual on the product website.
Electrical installation
- DIN-rail mounting and proper wiring must be carried out by a qualiﬁed electrician, in compliance with standards.
- Connect the MultiNode devices to the mains.
- It is recommended to record each device’s serial number, MAC address, and installation location (e.g., parking spot, ﬂoor number) to support maintenance.
  You can provision the devices either before or after electrical installation, depending on what works best for your workﬂow.
Connect your laptop
Connect your laptop to the device you want to use as the master node, e.g., the device next to the Internet gateway, with an Ethernet cable. By default, all MultiNode LAN 4TE devices start as regular nodes.
Open the web interface.
- Open a web browser and enter: http://devolo-xxxxx.local.
- Replace xxxxx with the last 5 digits of the device’s serial number.
Run the setup wizard.

When you open the web interface of a factory-default device, it automatically redirects you to the setup wizard.
- Click the button “Create a new network”. This sets the connected device as the master.
- On the above screen, wait for all nodes to join the network, then click “Continue. On the next screen shown below, enter the settings and click “Save and apply to all nodes in the network”:
  - Powerline domain name: Choose a clear name for the MultiNode network to help identify it.
  - Powerline password: Protects the powerline domain.
  - Seed: A number from 0 to 59 that uniquely identiﬁes a PLC network. It is recommended to leave this on automatic.
  - Admin password: Protects the MultiNode network management channel.
  - Web interface password: Protects access to the web interface.
- After the conﬁguration is applied to all nodes, you will be automatically redirected to the Overview, which lists all nodes in your MultiNode network as shown below. It is recommended to provide meaningful names to nodes, e.g., include a referencethe physicalical installation location.

FAQ

Can I use MultiNode with older firmware versions?

MultiNode is designed to work best with firmware version 7.16.5 or newer for optimal performance and compatibility.

Do I need to configure each device individually in the network?

No, you can use the setup wizard to configure multiple devices simultaneously for easier network setup.
