DSO RTU

EME eCON+ panel

Interfacing Fluvius telecontrole through an EME eCON+ panel over Modbus TCP.

The EME eCON+ is a telecontrole panel that relays the grid operator's Fluvius telecontrole signal to the controller over Modbus TCP, as an alternative to a direct Netflex link. The grid operator is still Fluvius; only the way its signal reaches the EMS differs.

The eCON+ converts the Fluvius signal for the controller and writes the production back.

To use it, set the telecontrole provider to EME eCON+ under Configuration → Grid & market → DSO RTU settings.

EME eCON+ requires a recent controller version. If the option does not appear in the dropdown, update the controller first.

Connection settings

Unlike the IO-based operators, the eCON+ carries only a Modbus connection, so there are no IO-port or switch-position assignments to configure. You provide:

Setting Description
IP address The address of the eCON+ panel on the local network (required).
Port The Modbus TCP port. Leave empty to let the controller use its default.
Slave ID The Modbus unit ID. Leave empty to let the controller use its default.
Mode The Fluvius telecontrol version the panel exposes: TC4 or TC5. This must match how the panel is configured; the controller reads a different set of values per mode.

TC4 vs TC5

How much the eCON+ conveys depends on the mode:

  • TC4: the basic set, a single active-power limit (as a percentage of the asset's maximum production) and a single reactive-power target.
  • TC5: the full set, emergency stop for production and for consumption, separate maximum grid injection and consumption limits, a reactive-power band, per-asset production/consumption caps, and the control reasons behind them.

If the mode configured in the platform does not match the mode the eCON+ panel reports, an incident is raised. Set the mode to match the panel.

Once connected, the grid states received through the eCON+ drive the same curtailment of PV, batteries, EV charging and loads as any other telecontrole provider.
