# EM24

### Configuration <a href="#configuration" id="configuration"></a>

Check that the Carlo Gavazzi meter is set to read both import and export power. An unsuitable mode may lead to:

* Missing readings of feed-in, or
* Feed-in being counted as offtake (on top of the ‘actual offtake’)

You can set this in the ‘MEASurE’ configuration menu on the energy meter. This should be set to ‘b’.

Warning

**Warning**

This setting may not be present on MID certified models (model numbers ending in PFA and PFB).

{% hint style="info" %}
**NOTE: RS485 Device Addresses**

* You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
* Use lower addresses first (1, 2, ...)
* For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits.

Set the Modbus address through the power meter's “Address” configuration menu.
