# ABB

Our EMS supports integration with EV chargers from ABB. ABB provides a broad range of AC and DC charging solutions for residential, commercial, and public charging.

The charger communicates with our EMS for monitoring and smart charging control.

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

After the electrical installation of a charger is complete, follow these steps to configure the charger:

1. Download the configuration app from ABB
2. On the dashboard, select "Configure a charger."
3. Enable Bluetooth on your phone, as this is necessary for the app to communicate with the charger during the commissioning process.
4. Choose a charger from the available list.

5. You can also select a charger by scanning the SN barcode with the app.
6. Be sure to scan the charger's SN bar code, which usually begins with "TAC" (although this may vary depending on the product variant).

7. After selecting a charger to connect to, enter the PIN.
8. Select below the option "EDIT CURRENT CONFIGURATION" - or if the charging station has not yet been configured, then select "Start from scratch."
9. Make sure your phone or mobile app is connected to the Internet for PIN validation.
10. Throughout the process, the app will display a pop-up confirming that all settings will be applied to the charger simultaneously once you get to the last step.

13. Select "Local controller" and then "Modbus TCP/IP"
14. You must set a fixed IP address in the charging station within the same network range as the controller.
15. Important: Always choose 502 as the server port.
16. For home and small business networks, a typical setup is with e.g. fixed IP address 192.168.1.50:
    * IP address: 192.168.1.50
    * Mask address: 255.255.255.0
    * Gateway address (the address of your router): 192.168.1.1
    * Server Port: 502
