MODBUS register set

INTEGRATE AN EXTERNAL METER

Make sure that you have a connection to the station. If you do not have a connection, see Establishing a connection to the charging station

The following meter models are compatible:

Modbus TQ EM300-LR (TCP)

Modbus TQ EM410/EM420 (TCP)
Modbus IPD Control (TCP)

Modbus Janitza UMG 512/96 PRO (TCP)
Modbus Janitza UMG 605 PRO (TCP)

Modbus Phoenix Contact EEM-MB371 (TCP)
Modbus Siemens 7KM2200 (TCP)

Click on LIST MANAGEMENT in the main menu on the left.

Scroll to External meter support and select On. Select the meter you would like to set up in the dropdown under External meter configuration.

Once you have selected a compatible meter, two additional lines will appear below it. Then look up the IP address assigned to the meter in your network router and enter it under IP address of external meter. The port number should be set to 502.

Then enter the maximum available current (in amperes) at the house connection in the next item Mains connection current limit (L1/L2/L3) [A]. Once for each phase. In our example, this is 160 A.

Next, set the safety margin for the external load (L1/L2/L3) [A] to the safety distance (buffer) to the maximum value in amperes per phase. In the example, this is 10 A.

Then enter the external load assumed in the event of a fault in amperes per phase in the drop-out level of the external load (L1/L2/L3) [A]. In our example with 9999 A, the assumed load is in-finite, so all charging points would be switched off.

Example: If you enter 20 A per phase here, the mains connection current limit is reduced by 20 A in the event of a fault.
Then set under External meter topology whether the meter only measures the external loads (Without charging station sub-distribution) or whether the meter measures the external loads and the charging station sub-distribution (Including charging station sub-distribution) together.

CONFIGURE LOAD SHEDDING

Ensure that the two potential-free contacts are connected correctly in accordance with the installation instructions. Make sure that you have a connection to the station. If you do not have a connection, see Establishing a connection to the charging station

Click on LIST MANAGEMENT in the main menu on the left

Without load management

Scroll to the Local section. Set energy management from external input to Activate ‘Opto 1 In’. With current limitation for energy management from external input, you can set how many amps the station’s power should be reduced to. In other words, 0 stops the charge in the event of a load shedding, 10 would reduce the power to 10 amps.

Finally, press Save and Restart at the bottom right.

With load management

Scroll to the Dynamic load agent area.

Open the drop-down status of external input 1 and select ‘Opto 1 In’.

Next, set the polarity of the external input. The external input can respond to a low-active (“Normally open”) or a high-active (“Normally closed”) signal. This setting must be selected in consultation with the responsible energy supplier.

Finally, you can define the current offset. In other words, how much each individual phase should be reduced in the event of load shedding. You should also discuss this setting with your energy supplier.

Here is another example: 16 A are distributed to the charging network. The current offset is set to -10 A. As soon as the load-shedding signal from the energy supplier is received, the power is reduced by the current offset. 16 A – 10 A = 6 A This means that load management continues to run at 6 A after shedding.

Finally, press Save and Restart at the bottom right.

Important: If you cannot save, scroll to the Local area and set the status of external input 1 to Switch off, then it will work.

ACTIVATE PLUG & CHARGE (ISO 15118)

ESTABLISHING A CONNECTION TO THE CHARGING STATION

The following options are available to establish a connection to the charging station:

Access via USB

Insert the micro USB plug of your cable into the corresponding port on the controller. This is labeled with the word “CONFIG”. Here you will find a photo of the controller and the corresponding micro USB port. Plug the other end of the cable into your PC. You can now enter the local IP address of the charge controller in the address bar of your browser: http://192.168.123.123/.
Access is via the operator access. Username: operator Password: JuiCeMeUP!

Access via Ethernet

Dynamic IP

Plug the Ethernet cable into the socket provided. If the charge controller receives an IP address from a DHCP server (standard configuration), which may be part of a network router, for example, you must research the IP address there.
Static IP

With a static IP configuration, use the configured static IP address.

A permanent static second IP address is configured on the Ethernet interface of the controller to enable configuration if both of the described paths are not possible or accessible for you. This IP address is 192.168.124.123. To do this, you must manually configure your PC to an IP address in the same address space and with the same subnet mask. For example, you can use the address 192.168.124.100 and the subnet mask 255.255.255.0.
The web interface is then accessed with the URL http://IP-Adresse/operator, i.e. in the last example with the URL http://192.168.124.123/operator.
Access is via the operator access. Username: operator Password: JuiCeMeUP!
