Hello gregbosma,

I guess you are talking about "Add page port matching".
You can find the setting in the options menu in the CAD segment.  See Image and/or the User Manual.

Have a nice day.
PLUS+1 GUIDE / How to stop automatically generating ports on page interface
« Last post by gregbosma on April 23, 2024, 08:32:47 PM »
Hi there!

Whenever I go to Page Interface Editor, I notice it automatically adds a bunch of bus ports and wire ports that I don't need. Is there a setting somewhere to disable this feature?

Communication / Messages from e Wheel
« Last post by SuperVinay on April 23, 2024, 09:53:37 AM »
Hello PLUS +1 Community,

I am completely new to this controller and CAN.
I am trying to control an electric motor using Plus +1 and Danfoss e-Wheel, I have MC024-120 controller.
I want to read CAN messages from e-Wheel and after some logic send an Analogue signal which will control the electric motor.
The firs issue is CAN messages from e-Wheel, as for example it is U16 signal for steering position, where values 0-4095 contains information of the steering position and 4096-65535 means no information. But when i read messages of specified Bytes using CAN explorer, it fluctuates a lot from 0 to 65000. It gives the correct values also but it fluctuates to point 0 and 65000.
I don't understand what to do now. I am attaching a screenshot here, in that the Red line is steering position, which gives correct value for most of the time stamps but then you can see it just fluctuates. Same happens with Velocity signal. As per e-Wheel catalogue, it sends message in 50ms, so i have same as Log Period in Service tool. Even if is limit the output it does not solve the problem as there will be an output corresponding to maximum the messages of 65000 value should be excluded completely, but also there is 0 which is not correct value but is there. I tried decoding the bits and only taking 12 bits, but of course it does not solve the issue.

I will be hugely grateful if anyone can help me here. Ultimately I need analogue signals to control an electric drive.

Thanks in advance.

I am developing an application that activates on/off valves sequentially, a pulse starts the sequence, write true to activate valve 1, cylinder 1 activates sensor 1 and turns off memory 1 (write false), I use the lowering button of the memory 1 so that memory 2 writes tru and activates valve 2 and so on until the entire sequence is executed. all memories have the same connection and configuration (bool). The problem occurs in memory 45, the name assigned to the first memory is MT1_B1 for routine 1, MT2 _B2 for routine 2, etc. The problem occurs to me in step MT45_B4. Is there any restriction on the names used for these components? Another possible problem is that I develop the application using an hwd file for mc012_110 (it is the hardware that I have available to run and monitor in servicetool), then I copy the routines and paste them into the program to use on the machine, which is a mc050_110, both files are compiled without errors, the drivers can be loaded into the controllers, both drivers can be monitored without problem using service tool, but on the field hardware (mc050) the routine is interrupted at step MT45_B4. Is there any restriction on the maximum number of memories and/or their names?
There is lots of ways to bake the NV cake, best read the help file to determine which 1 suits your application.

Select the function block in the component library
"Non-Volatile Memory Dynamic" or "Non-Volatile Memory Dynamic with Default" in particular
They are found in Component > Connections > Non-Volatile Memory Dynamic

Once component is selected press your F1 key on the board, this will pop up help file and the examples on how to use can be found in there, look in the menu on left, Example 1, 2 and 3 etc.

Thank you for the reply.

I'm still not quite sure how I use the None-volatile Memory Dynamic.

Any way you could provide an example on this? :)
Displays / DP610 Display issue, white screen
« Last post by samuelhj on April 22, 2024, 12:41:21 AM »

I have a DP610 display in an old snow cat for a ski resort here where the screen it self is just white on bootup, all the buttons work and apparently the manufacturer does not have these displays or anything to replace it.

I'm wondering if anyone knows what TFTs these displays use or if anyone has encountered this issue and figured out a solution? My guess is the TFT itself is gone bad (although it might as well be the TFT driver or ribbon cables etc)

The display uses J1939 to read information from a Cummins diesel engine and the hydraulic system (ran by old MC510 controlers).

The ski resort is ran by volunteers so I'm doing this pro bono just to help them out. Any information or help appreciated. :)
Controllers / Re: PWM output, proportional Valve
« Last post by samuelhj on April 22, 2024, 12:25:10 AM »
Hello I am new to Danfoss! THANK YOU FOR ANY HELP!!

I am trying to control a proportional valve with a PWM signal, the valve requires a 0 to 600mA.

What are the steps involve in this. as simple as possible?

1. Scaling. the valve is inversely proportional so 0mA= 3000PSI and 600mA=0PSI, I can use y=mx+b or scale function from library.
2. is there a function block needed to output a PWM? or can I send the scaled value to the Multifunctional Output?
3. how is the ping configuration done? Output mode option 3,4 or 5?

Thank you again !!

Since I recently had to deal with Bosch-Rexroth valves that wanted PWM signal, I'll share my insight on this, be aware I don't know your specific valve type so milage may vary.
The datasheet for the valve should at least have some guidelines on how to drive the valve via PWM.

What worked for the specific valve I was working with (which was contrary to the datasheet for that valve) was

Config per output:
PinConfig = 5
DitherAmp = 600 (60mA)

Config per group (you'll see this under the main page for Outputs)
CurChgLim = 111 (default)
DitherFreq = 150 (150Hz)
ReqFreq = 1000 (1kHz)

After messing around with the settings for a bit this proved to be very smooth way of controlling the valves in question.

I used the PWM driver from the function library (really worth the investment to save time).

Be mindful that not all outputs on all the danfoss controllers support dither and such (like MC050-118 does not support dither on output 41 and 46 iirc).

I am getting this on a project after updating to 2024 version
*** ERROR 587 *** [PLUS1_IDE] INTERNAL: Unexpectedly reached else in {TXmifPresenter.GenerateOutput}
Same project was working fine in 2023 version. What is wrong?

1. As a beginner yes I would use the scale Fb this is
2. Yes there is a PWM_Driver function block found in the outputs library, see attached
3. Ping config 3 is a good starting point, see attached
