DM1000 ETHERNET

[pinias]

Does anyone knows if there is a manual/procedure to use the ethernet on the DM1000 or DM12000?

I wonder what the capabilities for this feature are

Thanks

As far as what I have heard, Ethernet is now more like a valued item on the DataSheet than feature to use. Danfoss included it for a future purposes.

Hi There,

Does any one knows if the ethernet function on the DM700 or DM1xxx now works?

and how to use that of course.

Danfoss already sells the DM700 with the ethernet port

Thank you

Any updates on this?

I too would like to use the ethernet interface to communicate with other IP devices. I have not seen anything in documentation on how to achieve this.

Has anyone gotten any info from Danfoss or had any success doing this?

Hello,

As far as I know Ethernet should work on the DM1000 and some models of the DM700.
What I understand you have to enable it in the template. In the outputs page there is a Ethernet page, and the enable signal needs to be set to True.

If you don't get it to work, please contact PLUS+1 Helpdesk: https://www.danfoss.com/en/products/dps/software/software-and-tools/plus1-software/#tab-support


Have a nice day.

Hi Tor,

Thanks for the response. I have had an open ticket with helpdesk about this for a few days. Have not heard anything and that is why I posted in the forum.

I am aware of the ethernet output page and how to enable the interface, but how do I use it?

Where do I configure messages or packets to be sent and received and then used within PLUS+1 code? I would like to be able to send/receive data on the ethernet interface and I have not seen anywhere on how to do that with PLUS+1.

What protocols are available on the ethernet interface?

Thanks.

In case anyone else is interested in using the ethernet interface on the DM series displays, I received a reply from helpdesk on how to test. There were actually examples already in the hardware tab, I just did not look there. I will attach the screenshot on where to find the examples for TCP/UDP.

EXPERIMENTAL annotation fills me with great confidence... makes me all warm and fuzzy, yay

[Beezkneez]

Haha yes exactly!

I will say that so far testing has gone well. I am no expert on TCP/UDP but so far I have been able to successfully exchange data between the DM1200 and my computer with a basic python script using the socket library.

Great stuff.

Any chance you would be willing to share the .p1p and python script you are using there Beezkneez?

[Beezkneez]

Hello Mike_vd,

I'd love to share. I will again state that I am no expert, so this could be done better I am sure. It worked for what I was trying to prove before building the real deal though.

I opted for UDP because I do not care too much about packet loss. My application will be sending the same message over and over that contains operational values from the machine. I did also test with TCP and it worked fine, just don't need the extra bells and whistles TCP provides at this time.

I will attach a few screenshots. You will have the P1P so it should all be in there but just for future experimenting I thought I would mention a few things. When you change the message length on the PLUS+1 side you also need to edit the message length in the POU. Also, I start off with an empty array and insert data into it. I had never used it before but you can add an array file to GUIDE by right clicking on the project (you may already know that). The DM1200 project is too large to post so I will paste a google drive link below. The google drive folder contains the P1P and python scripts I was testing with.

You can either modify the network settings on your computer to match what is in the test project or modify the project and python script to match your computer, whatever you prefer. If all goes well you should see the output from the python script in the screenshot I attached.

Hope this helps!
