Danfoss X-Gate Gateway Solution
Equipment
This guide focuses at the current moment on the integration of the AK2 controller via CAN bus to the X-Gate. For the integration of the X-Gate with a BMS, PLC, SCADA, etc., please refer to the User Guide.
This guide also does not cover how to obtain the ED3/ED4 file.
What is needed
- X-Gate + power supply 24V AC/DC
- AK-PC 78x family (080Z0192) + power supply 24 AC/DC
- Display MMIGRS2 (080G0294) + ACCCBI Cable Telephone (080G0076)
- Cables for the wiring
Wiring with the MMIGRS2
General overview
2a. Connection between AK-PC 78x family and MMIGRS2
CANH-R connection should be done only on the first and last element of the network. AK-PC 78x is terminated internally and the last element of the network will be the X-Gate therefore do not terminate the display. Also do not connect a separate power supply for the display. Supply comes directly from the controller via cable.
2b. Connection between MMIGRS2 and X-Gate
Terminate the CANH-R on the X-Gate. Do not connect a separate power supply for the display.
Wiring without the MMIGRS2 (direct)
Terminate the CANH-R on the X-Gate. Do not connect a separate power supply for the display.
Skip chapter 4 if the MMIGRS2 is not being used.
Settings in MMIGRS2
Required App version: 3.29 or higher and BIOS: 1.17 or higher.
Depending on the configuration of AK-PC 78x, the main screen will appear slightly different. To access the MMIGRS2 display settings, simultaneously press 
the and the 
for a few seconds.
The BIOS displays “MCX:001” in the top right corner, indicating the CAN address of AK-PC 78x. The “50K” displayed represents the CAN baud rate.
These are the default settings, and no changes are needed. If for some reason you are seeing something different you can check the following settings:
- under “COM Selection,” choose “CAN” from the available options: CAN, RS232, and RS485
- Back in the BIOS menu: Press the down arrow to access the CAN settings. These settings control various aspects of CAN communication: Node ID, Baud Rate, Active Nodes, Diagnostics, and LSS.
- In Node ID you can select the CAN address for the display itself which is as default 126. In Baud rate we need to select 50K:
- under “Active Nodes,” you can see the connected devices:
Before the X-Gate configuration
After the X-Gate configuration
Settings in X-Gate
Access you X-Gate and log in using your credentials (default user: admin; password: PASS).
- Ensure that you have version 5.22 or higher:
- Go to Files and upload the CDF file (or ED3/ED4) for the pack controller:
- Go to “Network Configuration” and add a node with the following settings:
- Node ID: 1
- Description: (Enter a descriptive name – this field cannot be blank)
- Application: Select the appropriate CDF file.
- Protocol Address: Leave empty.
- In the Network Overview, access the X-Gate settings by pressing the arrow next to it:
- Go to Client fieldbus and enable CAN bus (G36):
- Go to “Supervisor Settings” from the Main Menu and verify that the CAN Baud Rate (SU4) is set to 50kbps.
- Go to the Network Overview, it can take 1-2 minutes to load the page. The question mark symbol next to the AK-PC 78x should now be replaced with an arrow, indicating a successful connection:
- Go to the Pack Controller settings. You should see various values displayed. Note that some values might appear as “NaN” if the corresponding functions are not used in the Pack Controller.
