License / Re: The whole lisencing structure of Danfoss is plain out stupid.

Yeah can do that but I do use function blocks, and this renewal process is stupid. Thankfully it seems to be changing for the better and I have contacted a company in Denmark that might help me get this resolved, thanks to Tor's suggestions that he emailed me. Just very infuriating having to wait months for something like this, putting projects on hold.

I use it heavily when dealing with math/equations and real numbers (two reasons because my math isn't great and guide doesn't handle real numbers)
I've also use it extensively for creating CAN message buffers/FIFOs.

Modify existing or optimizing code it is very useful.

It's also been able to convert existing guide screen shots or .scs files into ST code.

I update the LLM as I go when i find limitations of GUIDE.
For example, using words like DATA and OVERFLOW in ST will cause an error on compilation as those works clash with the C code complier.

Thanks for sharing! I've been doing some similar LLM experimentation by writing some skills to read/write the PLUS+1 GUIDE PLCopenXML files directly in order to avoid having to copy/paste between the LLM. In the absence of official MCP support, this is the closest I've gotten to something that truly ends up saving time because it enables refactoring in a way that the PLUS+1 IDE does not. I don't have enough confidence in it yet to share it, but thought I'd mention that it's possible and am curious if you tried going this route.

One thing I found is that LLMs seem to have a rough time understanding the cyclical nature of PLC programming, especially related to timers.

There is a similar thread over on PLC Talk that I've been following. It is an interesting read related to this topic: https://www.plctalk.net/forums/threads/does-anyone-here-use-ai-to-help-write-structured-text-codesys-beckhoff.148970/

Hello Lukey,
Have you run any tests?
For creating functions?
For modifying the program?
For optimization?

Thank you.  ;)

I created my own GPT to assist with Danfoss Plus+1 Structured Text Coding.

I've uploaded all the manuals and have worked out some of the nuances of ST in Guide that don't align to IEC 61131-3 language. (limitations and syntax's)

If you have any feedback or find any holes that need to be fixed please let me know so i can update the LLM.

When I've been in trouble in the past, I just got a trial licence. It gives you 30 days for them to get their act together.

PLUS+1 CS Hardware / Re: CS10 M2M Connection
« Last post by G30RG3 on March 30, 2026, 05:44:39 PM »
Disclaimer: I do not have the CS10's available to test any more, and am not sure if following was with the CS10's or the WS103's I used before.
To be able to connect a Wifi-Bridge, I needed to deactivate the bluetooth mode.

PLUS+1 CS Hardware / CS10 M2M Connection
« Last post by SJones on March 30, 2026, 05:00:24 PM »
i have been using the CS10 to setup a CAN Wireless bridge for over a year and have not had many issues,  setup was generally pretty easy.  However, I am now setting up the M2M connection with the latest version 125 CS10 program that is factory installed and I can not get the two CS10 to connect.  Just wondering if anyone else is experiencing any issues with the new version and if you found any work arounds yet.    When scan the Wifi networks with the CS10 in station mode, I can find the other CS10 but when I enter the password and click connect, it does not connect.  Best guess I have as of now, is that it is a password issue.

Hello samuelhj,

I am sorry to hear that you are having trouble getting licenses for the tools, and it shouldn't have to be that way.
The license model is changing and from what I understand the next step is for the user to be able to buy licenses/renewals online. Unfortunately I don't have any dates on when this will happen, but if I'm not mistaken,  it's only details left  to get it up and running??

I wonder if you could contact another Danfoss distributor?

Have a nice day.

I did, and they were unable to help (Win10  - OS wasn't supported any longer)
As the laptop was quite old, I replaced the hardware, and the issue did not reoccur, making me wonder what went wrong. It looked like a browser-license manager hick-up that tried to open a web page in Chrome / Edge but didn't receive a response from Danfoss, so the page timed out, and the Lic. Manager crashed. Guide and Service tool failed to load because of the "invalid license"
