Simulate I/O diagnostics cases for HS or LS digital output on MC4X

Fredrik Lorenc 3 years ago in IQANsimulate updated by Gustav Widén (System support) 5 months ago 4

It is possible to simulate different I/O diagnostics cases for i.e. current outputs on the MC43 by left-clicking on them and selecting status. A list of different I/O faults appear for the given output. However, when trying to do the same for a HS, LS or HS/LS digital output, the "Status" option is grayed out. I find this strange as the manual for the MC4X states that there are diagnostics for these output types as well.


IQANsimulate 4.00 released

Gustav Widén (System support) 5 years ago in IQANsimulate updated 5 years ago 0

Highlighted features

Signal generator

It is now possible to control the value of a simulation item using a signal generator. The signal generator contains a table with time/value pairs.

Import of measure file creates simulation items for each channel in the measure file that can be simulated (inputs). Values from the measure file are also imported so that you can play back a measured scenario.

Interface to other simulation software

ActiveX support implemented. Makes it possible to read and set values from external software, e.g. Microsoft Excel. There is an example file for this under the examples folder.

Remember input values and settings between simulations without having to save

Simulations can be manually saved as .isa4 files. There is also an automatically saved simulation, that stores the input values and all the settings between the simulations. When launching IQANsimulate, there is an option to select whether to use a saved simulation file or create a new one.

Keyboard shortcut for small input changes

In the simulation group view the arrows are used to select channel. Ctrl+arrows are used to change the value of the selected track bar. Added shift+ctrl+arrows to change values in raw value steps of 1 (smallest step available).

Possible to add channels to simulation group while simulating

You can now drag a channel from the functionality viewer to a simulation group without having to stop the simulation first. There is also a default simulation group, so it is not necessary to first creating a simulation group.

"Set value" function more accessible

Added a small popup below selected channel containing controls for setting values on the channel. Same method used for physical channels and for the "set value" function for stored and adjustable channels.

For more details, see release notes.


How is it possible to press 2 finger push button on md3 with simulator 5.06

claudio 1 year ago in IQANsimulate updated by Chris Litwin 1 year ago 1

Hello, how can I control (press) at the same time the F1 and F4 buttons of an MD3, using the 5.06 simulator. Thank you


Simulator 5.06 no shows software with mc43

claudio 1 year ago in IQANsimulate updated by Gustav Widén (System support) 1 year ago 1

how do for increase timer in software per ECU MC43 with simulator 5.06? Why the simulator 5.06 don't shows the software program with ECU MC43


Simulate Input and Output Statuses

Chris Litwin 2 years ago in IQANsimulate updated 1 year ago 7

Is there a way to set the statuses for inputs and outputs in IQAN Simulate 5? I know I can set COUT channels, but that option is greyed out on all other channels.


IQANsimulate 3.15.15 released

There was a couple of bugs introduced in IQANsimulate 3.15, that we now have fixed. Please use Help > Check for updates to download the new version.


USB Control of Valves in Simulate.

JoeGallimore 2 months ago in IQANsimulate 0

Is it possible to use a USB controller to adjust values in IQan Simulate? 

Ideally I'd like to use a midi fader board like the AKAI APC MINI to adjust certain values, without having to click through groups or separate values. 

Anyone done anything like this in the past? 




Simulate Clone file without any hardware

jan 3 months ago in IQANsimulate updated by Gustav Widén (System support) 3 months ago 4

On behave of service we like to simulate customer Clone files, without any hardware to be easily helpful to our costumer.

This should be able by opening Clone file with Design.

Our multi master application needs all masters in clone file: check.........If not : message -could not open- appears

Clone version, Simulate version and Design version should match: Check

While the Clone file is opening, message setting to default confirmation appears, both options [Yes] or [No],  applied, 

but both options give the same result:

When Design (communication set to [Simulate]) is ready: 

1....Run  [ ► ]  or (F9)   Simulate will boot (Set to [NEW] and ready for simulate:  

Unfortunately all (state parameters) settings are set to default

2....Send Project [ |→] of [F11]:

error -Communication interface error, socket Error # 10061-  appears

To your information: Used software version Design-5.08 and Clone (Run) -5.07 and Simulate -5.08.

Is there a way to Simulate customer Clone file as service wishes ??


Simulations not repeatable

NoePanier 5 months ago in IQANsimulate updated by Gustav Widén (System support) 5 months ago 3


I have been trying to validate some modifications I made on IQAN Design 6.02 with IQAN Simulate 6 but I realized that the simulations were not constant.

I tried to run a Simulation groups on two identicalDesign I copy/pasted so there could be no difference due to data stored but even with that, the data I got from the two simulations were not exactly the same. Usually, both would be very similar, but one would be 50 to 500 ms late from the other, or even sometime skip a data so when I make a checksum of the Mesure group's values in Excel, my results are not the same.

I was wondering if I was doing something wrong or if there was a way to fix it because I would have to validate more modifications like that and it doesn't feel right to have to play with the data to make them fit..

Thanks you.


Possibility to automate test sequence in IQAN simulate using scripts

Manoj 10 months ago in IQANsimulate updated by Edward Polzin (System support) 10 months ago 1

Hi Edward,

Is there any way to develop a script to automate test sequence in IQAN simulate?

I read that IQAN script tool can be used with IQAN Run to execute sequence of actions in IQAN Run but at present we don't have target hardware hence we need to test logic using IQAN simulate.

Thanks & Regards,
