IQANsimulate 4.00 released

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.

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

Fredrik Lorenc 1 year ago in IQANsimulate • updated by Gustav Widén (System support) 1 year ago 2

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 3.15.15 released

Ulrik Zakariasson (Software development) 4 years ago in IQANsimulate • updated 4 years ago 4
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.


Starting and stopping simulate

Ed Schippers 3 months ago in IQANsimulate • updated by Gustav Widén (System support) 3 months ago 1

Starting and restarting of a simulation takes a lot of time and after every (re)start it starts in the same view so when you are working on large projects you need to a lot of clicking before you reach the part that you are testing. this is particularly annoying when testing  functions that run only just after boot up.

It would be nice if there was a function that you could do a restart without stopping the simulation and/or a or a function that when a simulation is started the program it stays in a pre- operational state so that you can navigate to the part of the program that you are testing and then start the program simulation. 


Simulate Input and Output Statuses

Chris Litwin 4 months ago in IQANsimulate • updated by Roger Johansson 4 months ago 1

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.


Image on camera while simulating

Joshua 6 months ago in IQANsimulate 0

Looking for a way to display an image on the screen in place of the missing camera feed while simulating.  Trying to record screen activity to show during presentations and having the missing cam feed looks bad.


Simulate licens

Robin arvidsson 7 months ago in IQANsimulate • updated 7 months ago 6


Our client is requesting to be able to use simulate and our software to train their operators. 

Our software is programmed in IQANDESIGN 2.63 and needs the same version of the simulator. 

Do you still offer licenses for the simulate 2.63

how can we best obtain licenses?



IQANsimulate screen capturing

Brad.C 9 months ago in IQANsimulate • updated by Ulrik Zakariasson (Software development) 9 months ago 5

Is there a way to do a mass export of all screens in IQANsimulate?  Investigating for our technical publications team who want to save time documenting programs.


IQANsimulate and MD3 images/text display issue

Captain Sprocket 9 months ago in IQANsimulate • updated by Gustav Widén (System support) 8 months ago 1

I have encountered a weird occurrence when doing simulations with MD3 on IQANdesign 5.03.

It appears that especially "LAMP" images or text does not does not (always) load when switching between display pages. BUT the images/text are actually loaded but not visible and will only appear once I have minimized the IQANsimulate window and restore it again, then all the graphics appear and react as it should... Until I go to another display page again and have to minimize and restore the window again to see the actual result.

Has anyone else encountered this before? I have not yet noticed this behavior using the MD4 displays. 

This is kind of interfering with my debugging progress (trying to fix things that is not broken).

I haven't tested to see if this occurs on the actual hardware yet, but I am sure this problem is limited to the simulation only.


IQANsimulate error: Measure terminated (no valid application in target module)

Paul Summers 10 months ago in IQANsimulate 0

We have an application that was developed in IQANdesign but when we try to run the simulation we have the following error displayed and the MD4-10 is blank;

The system has approximately 8 arrays each sized for 2000 samples... if we reduce the sample side of each to < 950 samples, the simulation will run normally?!  Has anyone else experienced this?
