DISCLAIMER: The Octopus Gateway is no longer available through AiElements – please contact our support team (support@ai-elements.com) about connecting your Aquametro CONTOIL VZO 4 / 8 liquid fuel meters to the AiElements energy management platform through another gateway device (Carlo Gavazzi, Schneider, Accuenergy and more) available though AiElements.

1 Electrical Wiring

Make sure that all devices are powered off before any wiring is done.

The Acuvim II’s RS485 terminals of communication are A, B, and S (14, 15, 16):

  • A is differential signal +

  • B is differential signal –

  • S is connected to the shield of the twisted pair cables

—
If you have received a RS485 cable with your Octopus, you must connect as follows:

Yellow wire = A
Blue wire = B
Red wire = S/GND

If you are building your own RS485 cable, please follow the colour code and sequence below.


—

Cut/isolate the other wires before powering up the Octopus to avoid unexpected shorts.

You can then click the RS485 cable to the Octopus RJ12 connector.

2 Meter Modbus setting


You must set or check your meter’s Modbus address and baud rate via the meter display.

1. Pressing “H” key and “V/A” key simultaneously on the meter will go to the menu selecting mode. Cursor “Meter” flashes in this mode.

2. Press “P” key or “E” key to move the cursor to “Setting”.​

3. The Password page will appear, press “V/A” to validate

4. Press “P” key or “E” key to move the cursor to “System” and press “V/A” to validate

5. The meter shows the Address Value (this is the Modbus Address of the meter) –> Set it to 1 or other value and write it down

6. Press “P” key to move to next screen. The meter shows the BPS value (this is the baud rate of the serial line) –> Set it to 9600 and write it down

3 Octopus Software Configuration

3.1 Request the Octopus Software Tool (Windows)

3.2 Connect your Octopus to your computer

Connect your computer running the Octopus Software Tool to the same network as the Octopus.

3.3 Configure your deployment setup


Launch the AiElementsTool.exe Software Tool and create a new Branch, using the “+” button. Fill the “Branch Name” field with a short name for your project, and insert the serial number of your Octopus Gateway that you can find on its sticker or on its box.

Select the correct timezone in the Timezone dropdown menu. If you cannot find your city select the closest city to your site location which is in the same timezone.

Click on Network Configuration to enable Internet access for your Octopus. You can enable DHCP to get the Octopus to connect to the Internet automatically (Tick DHCP, click on Discover, and click on Set when the Octopus IP address is shown). For LAN access with manually assigned static IP addresses, you will need to get network parameters from your IT department and enter them here.

If you use a GPRS sim card for Internet access, you must enter your APN name and APN credentials here.

You must now set up the AiElements URL where data collected will be sent to. Click on Services button, and set the following:

  • Enable Service 1

  • Set AiElements as Service Name

  • Enter octopus.ai-elements.com as Service Host Address (IMPORTANT: When using GPRS Sim cards or when your firewall does not support the use of URLs, you must enter 52.50.202.103 as Service Host Address.)

  • Set 4401 as Port

  • Click OK.

You must click OK to create the Branch.

Once back to the Octopus Software Tool landing page, you can select your Branch and click the “Add” button on the right side to register the Accuenergy AcuVIM-II meters connected to the Octopus.

Find your meter in the drop-down menu and click Add.

At the next screen, you must enter the meter name, its Modbus address, baud rate, and whether it is connected to the Octopus Gateway via RS485 or via the LAN (RTU485 or LAN).

The device name must be a unique name identifier. Unless a convention has been pre-agreed with us, we ask you to use the following naming convention for choosing your unique name identifiers:

OctopusID-counter nameofdevice

(for example use 230007E7-1 Plantroom for the Plantroom meter if this is the first device configured via the Octopus Gateway ID 230007E7 and if Plantroom is the name you want to see in the dashboard for that meter. The next device will use the -2 counter extension etc)

Make sure to insert a space between OctopusID-counter and nameofdevice



For RS485 connections, you must set the same serial line settings registered within your meter and click OK.

IMPORTANT: Set the response time to 500 if using multi-channel meters or daisy chain configuration, to allow all the Modbus devices to return measurement in time.

For LAN connections, you must enter your Modbus device’s IP address and click OK.

The next screen shows you all the parameters available for that Modbus device. You may unselect some parameters if you are not interested in all measurements. Click OK to save your configuration.

The Modbus device now appears in the list of devices registered within your branch.

You can now add more meters if you have a daisy chain.

Once you have all your devices created, you must deploy your configuration onto the Octopus Gateway. Select your branch and click on the Deploy button.

On the pop up window, leave the default settings and click on Deploy.

Your Octopus Gateway is now configured for data collection from all the devices connected. We recommend that you save your project should you need to modify the configuration as a later stage. You will then be able to update an existing project when you add new meters.

5 – Check that the Octopus is collecting data from the meter

Launch the CDT.exe Software Tool, enter your Octopus serial number and click on Connect.

Once connected, click on the Real-Time tab, and verify that you are getting new event logs for the various electrical parameters every few seconds. This confirms that the Octopus is getting the readings from the meter via Modbus. You can then close the CDT tool. Verify your project file settings if you don’t see any data coming in.

5 – Submit your Octopus project to AiElements


Submit your Octopus .iwtx project file to AiElements via:

Octopus .iwtx Project File Submission Form

AiElements will use your project file to double check that the setup is correct and that data is being received from your Octopus Gateway unit and correctly showing in your dashboard. You will then receive access to your AiElements dashboard, and from then on you will be able to log in to your AiElements Dashboard at http://dash.ai-elements.com and get started!
