Is it possible to change an adjustable text parameter (or open the menu system) from an interactive message?

Dan Gray 8 years ago in IQANdesign updated by Pierre Fagrell 5 years ago 2

I have assigned the Action property of a button on an MD4 display page to a text parameter adjust item. I would like to do the exact same thing from a button on an interactive message. Is it possible to call up the menu system or an adjust item using qcode or some other way besides using buttons on a display page? Thanks, Dan

CAN network setting via adjust Functional Parameter?

Forrest 8 years ago in IQANdesign updated by Ulrik Zakariasson (Software development) 8 years ago 2

I would like to be able to adjust CAN Network parapeters with a functional parameter so I don't need countless iterations of the same program to get mixed up.


For example; I use a dedicated bus to speak to the Chassis computers. Most vehicles run at 250 kbs, but more and more are 500 kbs.


Another example; Most joysticks will be on short enough wires to stubs, but some cases I will have to do dual joysticks both quite distant (wire-wise) from each other and the MD3. To make that work I will need to make them their own backbone and turn off the terminating resistor on the MD3.


just that quickly I have 4 versions of the same program I need to keep up-to-date.

Jan Gillesen 8 years ago in IQANdesign updated 8 years ago 1

I like to use the chair switch in a seperate IDC in the activating group, allowing movement from the moment the input has been zero. In that way, the output can not go to high speed when a person is holding a joystick when taking a seat. The joystick has to be "reset to zero" first. :)

2017 Training

Kevin 8 years ago in IQANdesign updated by Gustav Widén (System support) 8 years ago 3

We are keen to be able to attend some IQAN functional safety training if possible. Will there be some running either in the UK or Sweden in 2017?

TSC1 Settings

ksilovich 8 years ago in IQANdesign updated by Ulrik Zakariasson (Software development) 8 years ago 4

1)It would be nice to be able to set the TSC1 SA with an "Integer math".

When we configure a truck, our techs are given an option of engine type and then the program has an if statement that sets the SA with multiple TSC1 messages and engines.

I know you can now use an Integer Parameter, but that doesn't help me.


2) I would like to beable to control the "Use Checksum/counter" with a "Internal Digital" as we have some engines that require it on and other that require it off.

Greater resolution for trigonometric function

LPC 8 years ago in IQANdesign updated by Gustav Widén (System support) 8 years ago 5

Is it possible to have an update on the trigonometric functions?


I want to calculate the distance between geographical coordinates, but for that I need great precision on values returned by sin, cos and atan functions.


It says the minimal input for those functions is 0.1 degree, but in order to compute a legitimate value, there shouldn't be a minimal value other than 0.


Thanks for the feedback

Have you considered using small angle approximation?


sin(theta) ≈ theta (in radians)


See https://en.wikipedia.org/wiki/Small-angle_approximation

Xc10 current controlled outputs

John Baldwin 8 years ago in IQANdesign updated by Gustav Widén (System support) 8 years ago 1

Can the XC10 pwm outputs be also used as current controlled? I looked at the documentation for the cm3620 module (i believe the xc10 is a re branded cm3620) and it has current sensing on the low side outputs. Is it possible to do current control for the pwm outputs, or at least is there a way to read the current on these resistors so I could do my own in app current control?

Charging control ?

Krzysztof Bręk 8 years ago in IQANdesign updated 8 years ago 1

Hi

I wonder how to controling battery charging in iQAN Design. Should I use voltage input, where maximum voltage is 5V but from battery going 14,4 V. What should i do?

FGI Calculation/Sample Time Question

Nick Pridham 8 years ago in IQANdesign updated by Ulrik Zakariasson (Software development) 8 years ago 1

If an FGI transitions through 3 layers of function groups then does it take 3 cycles for a root value to reach its final destination ?


In other words does the IQAN OS pass on all root values regardless of the calculation layers in one sample time?
