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.

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.

Displays / Re: DM1200T Displaying Licence PDF

Been a while since I worked on a new project involving these displays, but if I recall correctly you need to delete the licence page within the main Application.

Displays / DM1200T Displaying Licence PDF
« Last post by NickHankin on October 03, 2025, 10:03:14 AM »
Hi,

I'm a very new user of Plus+1, this may be a really obvious solution.

I am programming a DM1200T to be used as a display for giving live sensor readings on a vehicle.

Whilst waiting for the screen to arrive, i developed the programming for a 430 screen and tested it. This is worked well.

I made the same program on the DM1200T template and when it arrived, i uploaded the program using the service tool and the file downloaded successfully. But the HMI is only showing the licence agreement PDF. I can scroll though it but that's all i have.

Am i missing something with the new type screens that i must do in the programming, or have i got a faulty unit?

Thank you, nick

Controllers / Re: How to recover MC050-120 after power supply shutdown during software downloading
« Last post by Tor on September 23, 2025, 08:29:27 AM »
Hello anpham,

This sounds strange.  Does the Service Tool state that the unit is in Bootloader or isn't the unit found?

Some things to check.
- Recovery ECU  (already done)
- Check cables and connectors
- Test with a second controller to check that all connections and tools are working.

If you don't find a solution, please create a case for PLUS+1 Helpdesk:  https://www.danfoss.com/en/campaigns/dps/plusplus1-support-form/

Thank you.

Has anyone used QT design studio for Danfoss HMI development?  Any thoughts or comments around the ease or speed of development?

Controllers / How to recover MC050-120 after power supply shutdown during software downloading
« Last post by anpham on September 22, 2025, 11:43:52 AM »
Hi,

I had an accident with the power supply during software downloading to MC050-120. I tried to used the "System/Recover ECU" to recover it but was not successful.
Is there anyway other way to recover the MC050-120?

Best regards,
