You need to use function block for the joystick so it's linear 0-100%.

Then the PWM block to drive the valve.
You also need to figure out the dither frequency, see this post: https://www.plus1forum.danfoss.com/index.php?topic=1816.msg6167#msg6167

General controls / Re: Parameter programming of PVEH-CC series 7.
« Last post by samuelhj on October 10, 2025, 06:44:10 AM »
I'm adding some information to this thread for anyone wondering about this or other parameter pages.

After downloading the stuff you need for your sensor or whatever you are working with in the Plus1 download centre:
Within Guide, you can open service pages for DOWNLOADABLE content by going through these steps:
On the right panel you can select HARDWARE. Find the hardware you previously downloaded in the update centre. Select the tree, go down from there to each substep and find the hardware you downloaded and hopefully there's a service page for that particular hardware. A bit hectic but works.

Had to reconfigure some sensor someone sent me and took be ages to figure this out, probably missed the pdf that explains this somehow...

Hope this helps someone in the future.

General controls / Danfoss RedCAN
« Last post by samuelhj on October 10, 2025, 06:36:18 AM »
Hello.
I'm wondering if anyone has any information on Danfoss's RedCAN.
I can't really find anything on the internet about it, apart from it being a standard someone implemented in the DP6xx displayes?

Here are links to Danfoss videos...

The cost of the QT developer is significantly cheaper if your company revenue is < 1M per year.

Hello,
Thank you for your question. It’s a very interesting topic.

I would also like to have information about development with Qt. What are the advantages? What are the possibilities? Are they different compared to the Guide?

Could an admin share information from Danfoss with us?

Have a nice day

Displays / Re: Writing an LHX to Dp6xx
« Last post by Rem on October 08, 2025, 09:34:01 AM »
Hello,

Do you only have the LHX file and not the P1P file?
In that case, you can only download the LHX to a similar screen.

If you have the P1P file, you can then modify the hardware file in your program for a 610 screen (or another type) and try to compile it.

Have a nice day.

Displays / Writing an LHX to Dp6xx
« Last post by samuelhj on October 08, 2025, 08:16:37 AM »
Hello.

I have an LHX file from a legacy project (Pistenbully groomer) but the display is broken.
can different hardware versions be programmed from the same LHX file (They are not using the extra features of the 620 and 610 display) to the a replacement display if the hardware version is not matched?
I see a lot of 610 displays around but not too many 600 displays.
So question basically boils down to, can it mismatch hardware version but still be downloaded?

PLUS+1 GUIDE / Re: A system with multiple controllers - GUIDE project architecture
« Last post by Lukey on October 07, 2025, 02:06:47 AM »
I have had to use controllers when using some library blocks that only work with controllers.
1 example was a Danfoss orbital motor rotary sensor, the feedback i required from the input was the .per, which from memory is time between pulses, this function is not available on the expansion modules.

My program architecture is to always have 1 master/controller and the rest of the modules being of first preference expansions or else controllers(via rx/tx) that are simply remote I/O.

The issue i have is having multiple controllers requires multiple projects, this is tedious, I was hoping for a better way.
I thought the Modules feature of GUIDE would address this, however i have yet to find a practical application where i would implement different Modules in 1 GUIDE project.

When we can use the IO modules we do so, but they do not always suit.

I have also been creating a GUIDE project per ECU, then writing CAN TX/RX to communicate among them.

I'm curious what the additional controllers are providing that the IO modules don't already provide. Is it just a need to distribute logic? So far I've tested one MC and several IO (combination of IOX and OX) and didn't seem to hit a roadblock that would require a controller instead of an IO module.

Quote from: Fredrick on October 03, 2025, 10:07:19 AM
In multi-ECU systems, I typically designate one ECU as the primary controller, while the remaining units operate as distributed I/O modules. The control logic resides entirely within the primary ECU and is communicated via CAN to the secondary ECUs

In the case of a controller, a display, and IO modules, I've taken a similar approach. However I have found it tedious to write the CAN messaging between the controller and display whereas the IO modules come with that already included.
