MD3 Adjust groups

Masia Jean-Baptiste 3 years ago • updated by Ulrik Zakariasson (Software development) 3 years ago 3


Is a first time I have this problem wich the MD3 .
When I want adjust my parameter since the MD3, is not possible.
In my programme, I Have créated the adjust groups ("Réglages")
with a PIN code

When I look the MD3, I have a green clamping for indicate to the user that there is a PIN code.

with the Up and Down button , i select my adjust group and i push on the ok button and i write my PIN code.

After, I Want select the Function parameter but it's not possible. I am blocked and I have another green clamping.

When I look my adjust parameter, Enabled is on YES .

Its possible to tell me why my Fonction parameter is boqued ?

For information, I have a 4.03.27 Iqan Version

Thank you for you help.

One reason: Are the parameters in a function group, which is disabled?


Eliminate a wasted J1939 CAN BUS

Forrest 3 years ago • updated by Ulrik Zakariasson (Software development) 2 years ago 1

I run a dedicated J1939 Bus to speak with the Vehicle CAN. I imagine most do it this way.

Now that I have to cover for the possibility of both 250kbs and 500kbs J1939 vehicle CAN buses, and do not want to have multiple versions of software floating around if I can help it (tried it, can be a bit of an unneeded mess), I am running out of CAN Buses on my MD3s.

The way it is now, I am planning on setting up 2 vehicle can buses, each with their own "engine", then pick which engine to enable in the settings (250kbs, 500kbs, or disabled). Unfortunately, that leaves me with a wasted Bus since I can not run both the 250 and the 500 to on the same physical CAN Bus pins. An empty Bus might even throw an error. I haven't tested it yet.

It would be nice to be able to select J1939 bus speed in the software settings or be able to disable the unused bus in the settings. Either would free up a bus on the MD3 so I wouldn't have to put absolutely everything else (Master, Expansion, Diagnostic, and J1939 components) all on the same physical bus.


IQAN Network Key Not Recognised Error

Kevin Arscott 3 years ago • updated by Gustav Widén (System support) 3 years ago 1

Hi we have had a customer report 'IQAN Network Key Not Recognised' error appearing on MD4-7 with a 3 master system (2 x MC3). We are currently unable to access logs and see if this error has logged. There is no photograph of the error displayed on the screen, the operator only recalled it after the shift, therefore the error may have been worded slightly different.

Is there information on this type of error and what it means? I have looked through the manual and cannot find anything along these lines. I wondered if it was a project ID mismatch error?


MC3 failure reaction

What happens if the application running on the MC3 crashes? Does the safety ASIC reacts and brings all of the outputs to a safe state (unpowered)? Thanks!


digits pin code

jan 3 years ago • updated by Ulrik Zakariasson (Software development) 3 years ago 1


Is there any way to add more digits as 4 to the pincode

Wilfried 3 years ago

Standard, every pincode in IQAN has 4 digits, so standard, it is not possible to have more digits

This is my système

In my log fil, i have toow calculateur

Coffret démarrage log = MD3

When the Log MC3 is full, the MD3 not saved the news erreur yet the log full behavior is put on Continue logging.

In the help his write :

Continue logging makes the log delete its oldest records to make room for newer. Use this option if it is more important to see the latest events.

Why my news erreurs is not saved ?

In IQAN design how do I select from a joystick input or potentiometer input to drive a the same current output

tcelectronics 3 years ago • updated by Gustav Widén (System support) 3 years ago 2

I'm trying to select from two different inputs to drive the one output, using a joystick for travel mode input and a potentiometer for sweep mode input. IAny ideas or any programming examples.


Software version running on machine?

Kevin Arscott 3 years ago • updated 3 years ago 9

We have a machine in the field running 3.19 and we need to update the software remotely. To avoid updating the firmware (it takes too long and sometimes fails half way though updating) i need to revise the software using the correct version of IQAN Design originally installed on the machine. The machine appears to be running on firmware version in the MD3 and in the MC3. This is a multi master system.

Can anyone confirm which version of 3.19 I need to build the software change into to prevent having to update the firmware in the machine please? There are multiple versions of 3.19.9 and if I choose the incorrect one it will update the firmware.

I have tried to simulate 3.19.7 and 3.19.9 and use IQAN Run 3.19 to look at the firmware revision but the firmware does not appear to match what we have running in the machine. When I simulate I get 3.19.2.


Fault code on MC3

Kevin Arscott 3 years ago • updated by Vivek 1 year ago 11

We are getting fault code 2 orange / 1 orange / 1 orange / 9 orange / 4 red / 1 orange on MC3 controller. Does this error code mean internal error/OSC (4:1 in MC3 manual)? If so is there any way of getting more information on why the controller is switching off and more details on that specific error code? Fault appears to be random and only sometimes goes into error state, sometimes module boots fine with no issues or error codes. System is 1 x MD4, 2 x MC3. Intermittent fault present on both MC3 controllers. Both MC3 controllers have CAN Open device attached to each. We have used these CAN Open devices before with success.


MDL USB plug

Jon 3 years ago • updated by Ulrik Zakariasson (Software development) 3 years ago 2

Does anyone have the pin out for the MDL side of the USB connection? A previous employee had de-pinned the MDL end for some "testing" purposes but never put it back together or wrote down the pin out. I have searched threw any literature I have to no avail.

Arno Heeren 3 years ago

Hi, you find some information about the USB connection on page 18 and 19
