Hello,

I am working on an internal tool that converts .dbc files into POUs that can imported into GUIDE as a single source of truth for CAN communication. I have the actual CAN communication functionality implemented using the functions provided Middleware_CAN_Base_Public (from the middleware library), but along with this I would like to implement a sort of "watchdog" that monitors for connectivity issues. I was initially trying to use time.h (the standard C99 header), and it did not work. I currently have this set up by passing OS.ETime into my POU and saving that to a static variable when the corresponding CAN message is received. From there I compare the passed in value to the static variable, and if a certain amount of time has passed since the last message was received an output variable is set to true indicating a timeout or communication error.

Now, it would be really nice if I could get the OS.ETime value directly from within the POU instead of requiring it to be passed in (there will be many POU calls so the fewer manual routes I have to do the better). The "OS C APIs in PLUS+1 GUIDE" section in the GUIDE user manual gives me hope that it is possible because it states "The presence of an APIs sub-node under the HWD node within the Project Manager tree indicates that the used HWD offers OS C API support for your project."

But I am also doubtful for my situation because I am using an MC050-110 (MC050-110/112-0_nl ver:70089372v230), and I do not see the aforementioned "APIs" sub-node under the HWD node. Is the API functionality missing from this controller or am I just missing something?

Any help would be greatly appreciated.

Thanks,
JT

Hey There,

I guess it is what it is but just in case.

I believe until early this year it was possible to open a file for the MC050-010 controller and get it modified if needed and compiled again for download.

now it seems it is not longer supported by GUIDE,

The question is, do you know if there is a way around to get a MC050-010 project file updated and compiled?

Otherwise I guess it will go to the recycling bin -the controller-

Thank you

Hi Rem,

Good that you found a solution to your question.

Regarding HWDs that support UDS?
When the Cyber Resilience Act (CRA) is kicking in at the end of 2027 all Danfoss products will have UDS support.   As far as I know no released product support UDS yet.
I was hoping to find some kind of plan/timeline to when different hardware will be updated, but no luck.  I believe this is hidden deep down within the developer groups.

This is unfortunately the best answer I have for you at this time.

Have a nice day.

Hello,
I'm looking to disable the functions of a p1d file so I can send it to a student without them being able to download the lhx file or copy the program.
I thought about sending them an scs file, but since it's a screen, they won't be able to view the user views.

Is there a solution?

Thank you.
Have a nice day

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.
