Graph time scale

Conrad Elektro 3 years ago in IQANdesign • updated 3 years ago 6

Hello, We like the possibility to add graphs with IQANdesign. How can we set the time scale of the graph so that it starts again after 1 second instead of 50 seconds? We like to monitor a movement in 1 or 2 seconds. With the time scale of 50 seconds we can not see the result properly. Is it possible to change it or is there a workaround?


Backlight auto-adjuste

Florent Mirieu de Labarre 4 years ago in IQANdesign • updated 4 years ago 3


My customer use product during the day and the night. The problem is in night the backlight is too hight. It is possible to change with the menu, or with a button to switch in night mode. it's work but is not auto-adjuste.

Three possibility to do an auto-adjust-backlight

1 - add a light sensor (light Garmin GPS)

2 - add a function who calculate the sunrise and sunset with latidude/longitude in input. I have made this fonction it is works great. But if the system loose date or the customer change place (it is possible with our product), it doesn't works. Like that there a number 3

3 - add a GPS module on your module (now a GPS module is very low cost (5$)), like that always on time, you have the real speed, and you can use the auto-adjuste-module



Simulink --> C-Code --> IQAN MD4 Display

Fero Freitag 4 years ago in IQANdesign • updated by Gustav Widén (System support) 4 years ago 1

We have created a software model in Simulink and Stateflow. For developing the prototype we have a CAN interface used. Thus, we could create a complex algorithm. By code generator we have created from the algorithm C code. Now to the question: Is it possible to C code to be loaded on the display MD4?


How do master modules behave when they become optional

Kevin Arscott 4 years ago in IQANdesign • updated by Gustav Widén (System support) 4 years ago 6
We are using a system with two master modules, MC3 and MD3. I have several questions regarding how the system behaves when disconnected. We are intending on having only the MC3 set as optional as all the fault logging is done within the MD3.

What happens if the can line is disconnected when the system is live? Will we get any errors within the MD3 or notification to say that its been disconnected?

Also we are having an APP out sent to the MD3 to we are able to flag the disconnection of the modules in the MD3. Will the MD3 be able to pick up the APP in has dropped to low after a disconnect? Im assuming we could have a similar setup on the MC3 logic also?

unable to update/download project with MD4 ethernet connection

David Dufour 4 years ago in IQANdesign • updated by Leon Valentin Novac 4 years ago 26

I'm actually try to send my project to multiple master configuration.

I have this configuration :

Enclosure 1
MC3 (0) + MD4 (1)

Enclosure 2
MD4 (2) + MD4 (3)

Enclosure 3
MD4 (4) + MD4 (5)

Enclosure 4
MD4 (6) + MD4 (7)

I set the can bus A as Diag network, can bus B as master bus.

Also, I have 4 XA2 connected on the can bus C on the MC3 unit.

I used all node tag without termination.

when I have a success (I need to power down 2 or 4 MD4 to be able to transfer the program),
I got MD4 with version number on the right bottom of the screen.

there is a limitation of the number of equipment who can be updated over the ethernet connection of a MD4 ? is the Can bus adapter will be safer and more stable ?

Also, I tried to transfer the program with all MD4 on the project and I always have the same issues.

Once time I got 2 MD4 with the normal startup page but without communication with the MC3.

Any idea ?



remote connection message on MD4

Frank GUO 4 years ago in IQANdesign • updated by Anders Båth 3 years ago 7

Is it possible to have the 'remote connection acceptance' message turned on or off? I am connecting to a MD4 remotely using network. Every time, it will ask to accept the remote connection. Would like to see if that message can be turned on or off somewhere.


MD4 display orientation

Kevin Arscott 4 years ago 0
The display isn't mounted centrally in the MD4 housing therefore you get thicker bezels around the top and sides of the display. Can the display orientation go one step further and rotate 180 degrees so we have the thin bezel edge around the display at the top rather than the bottom?

Although it doesn't seem like much, it would look aesthetically more pleasing on a project we have coming up.

Array channel as app-out function

Jan Gillesen 3 years ago in IQANdesign • updated by Gustav Widén (System support) 3 years ago 9

Is it possible or will it be possible to feed a complete array channel through an app-out / app-in function? We cannot manage to do so right now.

Using an array channel we could combine a lot of low priority data into a single app-out.

( We've tried using a parallel J1939 can line in the software but cannot combine it with a master and diagnostics line. )


Auto-save measure files in IQANrun

Jan Gillesen 4 years ago in IQANrun • updated by Ulrik Zakariasson (Software development) 2 years ago 5
We sometimes lose our measure data when accidentally navigating to an adjust group or another page directly after doing measurements. An auto-save function, or a pop-up when stopping a measurement would be very helpful.

It would also be useful to add more metadata to a file, for instance Machine ID, software version, time stamp or certain machine settings. 

Measure & Adjust Groups - Appearance Customisation - MD4

Nick Pridham 4 years ago in IQANdesign • updated by Ulrik Zakariasson (Software development) 2 years ago 4
I had a Human Factors change request on a project: The request relates to viewing lists of measure and adjust values on the MD4 screen.

  1. Theme choices: Example alternative lines show white text black background then black text with white background as a way of making long lists more readable.
  2. Font size and colour
