Adjust Digital Memorizing channel on MD4

AxelC 4 years ago in IQANdesign • updated by Ulrik Zakariasson (Software development) 4 years ago 3
I use MD3 and MD4, i did a small code that use a Memorizing channel (MEM) for a digital value.
I find a bug when I use the MEM as Adjust on the MD4
On the MD3 it work good

You can see on the screenshot:




I only test it in simulation for now

It look like some pointer issue, clicking on the top or bottom text doesn't change the MEM value. so it is not a only a printing issue



Hope you can reproduce the issue If not I could send you a project

Large Array Usage

Nick Pridham 3 years ago in IQANdesign • updated by Gustav Widén (System support) 3 years ago 1

IQAN design 4.01: MD4 - 7" - The IQAN design manual indicates that large stored arrays can impact on utilisation. Is there any guidance or application experience for usage of large arrays. I am planning approx. 80 x 100 cell array channels.

MD3-Adjust Group-Reference Channel-Will only display to one dec place on the MD3 screen.

Nick Pridham 4 years ago in IQANdesign • updated by Ulrik Zakariasson (Software development) 3 years ago 3
I would like the decimal place count for the reference channel to automatically match that of the parameter being adjusted.

The IQAN run view is fine.

TP Channel Question

Nick Pridham 3 years ago in IQANdesign • updated by Gustav Widén (System support) 3 years ago 4

Is there a Q code function for parsing out the value of a text string (TP Channel)? I want to write the ASCII ref for each character of the text string to an array.

Q code for how many characters in the text string?

Q code for get character 7,6,5,3,2 ... from a TP channel?

adjustable button not working - 3.18 - no passcode prompt

Zach 4 years ago in IQANdesign • updated by Ulrik Zakariasson (Software development) 4 years ago 2
On my computer, I click on an adjustable that is locked by the third pin code on the machine.
I get prompted for a pin code, enter it, and then can adjust as I desire.
I have a windows 64bit system.

On the md3 and on the md4, the pin code prompt does not come up, and the adjustment can't be made.

This machine has three pin codes.
Only one of the sets is not working that I am aware of.
Three coworkers, with their three laptops, could not get the pin code page to come up.
I wondered if it was because they are using 32bit machines maybe.

I don't understand why the md3 and md4 will not prompt for a pin, or let them do an adjustment.

What I mean is that when I hit the button on my computer in the simulator, I get brought to the pin entry page. I put in the pin. I then am able to do the adjustment.

Two coworkers are unable to be prompted for a pin or make the adjustment with their laptops.
They also are unable to get prompted or make an adjustment at the machine on the md3 or the md4.

Program is in 3.18.

This is kind of urgent.

Calculation Overflow - MD4 Nuisance System Logs

Luke Ricker 3 years ago in IQANdesign • updated 3 years ago 2

Is there any sort of way to disable "calculation overflow" from making a log in the system log in an IQAN 3, MD4 application?

I know that I should probably make my program not have calculation overflows in math and J1939 output channels in the first place, but when these errors pop up, despite the best programming intentions, and are logged, it worries the customer, who usually thinks something is wrong with the machine.


Thanks!

Ajdusting Dither Amplitude

Aurelio Romano 4 years ago in IQANdesign • updated by Gustav Widén (System support) 4 years ago 1
Is there a way to change the dither amplitude in the IQANdesign software? We have an application where we believe the dither amplitude is causing the valve to go unstable and would like to decrease the amplitude to do some testing.

IQAN 4.00 J1939 parameter in bug

Frederick Prigge 3 years ago in IQANdesign • updated 3 years ago 4

I have a block of code that worked well under v3.19 that is missbehaving under v4.00.


A MC31 master is receving J1939 frames from another non Parker device. In debug mode the frames are "green", meaning no timeout situation. The associated J1939 parameter is "red" and I am getting the replacment value. I first tough it must be a J1939 error check, so put the J1939 error check to "no". Same situation, no change, parameter is "red".


If I remove the scaling and offset ot that J1939 parameter, it works, and becomes "green"! I then need to do the scalling/offsetting in a math channel. This is not normal! Please advise.


Thanks for your help.

Program optimizing

Tuomas 3 years ago in IQANdesign • updated by Ulrik Zakariasson (Software development) 3 years ago 2

I have learned to use Qcode and its great tool to make your program more simple.

However, I noticed that when you add many functions inside same channel (like MAC),

the Component Count value in Project statics increases a lot even it should be less than before? Example before I had 5 different MAC channel what I add in same MAC channel using Qcode, still Component Count value increased even it should be less than before?


When you want to optimize your program running power what method gives best result;

-Add many functions in same channel or keeps functions separate in own channels?


Merry Christmas to everyone! :)
