Step-by-step guide:

  1. Log on to the DLM Master charger by doing as described in Connecting to charging controller with laptop
  2. Open the "operator" page and find the following parameter "Meter configuration (Second)" Set this parameter according to the type of meter installed. For more information on different types of meters, see the information box below.
  3. After this, find the "External Meter Support" parameter on the "operator" page and switch it to "on"
  4. Furthermore, the following parameters are set according to the installation:
    1. "Main distribution Limit (L1/L2/L3)"
    2. "External Load Headroom (L1/L2/L3)"
    3. "External Load Fallback (L1/L2/L3)"
    4. "External Meter Location"
    5. External Load Averaging Length (sec)
  5. For more information about these parameters, see description below.
  6. When information is filled in, select "Save & Restart" Once the charger has restarted, confirm that the DLM-Master is communicating with meter by looking at the "DLM" tab

Beskrivelse av parametere:

"Main distribution Limit"

Current limit for DLM available for distribution to EVs and additional energy loads. This value is typically higher than the 'EVSE Sub-Distribution Limit' above. An external meter is required to detect the energy consumption of the additional load. 

"External Load Headroom"

Safety margin to avoid transient overload situations. The algorithm will keep headroom towards 'Main Distribution Limit'   

"External Load Fallback"

In the error case, where the external meter is disconnected or fails, 'External Load Fallback' is assumed as consumption of an additional consumer. Setting to a high value will result in no current available for the EVSE sub-distribution in that particular situation. Thus, charging would stop

"External Meter Location"

Specifies, how the external meter is connected: in case the external meter measures the energy of chargepoints and additional consumer altogether, the value shall be set to 'Including EVSE Sub-Distribution', otherwise to 'Excluding EVSE Sub-Distribution'.

"External Load Averaging Lenght"

Meter values will be averaged in order to avoid transients.

External current meter Modbus:

Both Modbus and Modbus over TCP/IP are supported. In the case where a Modbus meter is installed, a suitable Modbus cable must be installed between the DLM Master and Meter, preferably with end sleeves to the following ports in the DLM Master charger shown below:

21B and 21A connection.

It is also important to set Modbus parameters in the meter accordingly

Adress: 2

Baud rate: 9600

Parity: None


External Power meters TCP/IP:

When using Modbus over TCP/IP, you must ensure that the current meter is connected to the same IP network as the DLM Laderne is connected to. Furthermore, the Meter must be assigned a fixed IP. This is done either in the network's switch or locally in the current meter. When using Modbus over TCP/IP, the DLM Master must also be configured so that it knows the IP of the Meter.

Follow the user manual for the power meter when configuring it.

when using the Phoenix Contact EEM-MB371, configuration is done by connecting the laptop to the meter with an Ethernet cable.

In order to be able to communicate with the meter, the laptop must be set with a fixed IP. In Windows, Ethernet Settings can be found by searching in the start menu.

Click on "Change adapter options"

Here you right-click on the icon for the network card the cable is connected to and select "properties"

Then you will find Internet Protocol Version 4 (TCP/IPv4) in the list

select Properties/Egenskaper

Then select "Use the following IP address:"

Fill in with IP: 192.168.1.50

Subnet mask: 255.255.255.0

Select ok and close the windows. Open a web browser and open the address:

http://192.168.1.2

The default setting for the password is “adm1n”.

Log in with information from the user manual for the meter and change the parameters according to the installation.
