Can RTC and TDA be enabled at the same time?

Jamy 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 4

I'm adding a Axiomatic RTC controller with J-1939 to a legacy machine. When I revise the IQAN 6 software, can both the RTC and TDA be enabled at the same time without errors? If RTC and TDA are enabled and the external TDA (External RTC controller) is not present, will the MD4 default back to the internal RTC?

Reset adjust item parameter to default

lbartik 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 3

When I am using the parameters menu to adjust any of my integer parameters, there is a Reset... option in the kebab menu, what is the intent of that function?   It seems to recall the stored/retained value from the beginning of the current power cycle, not the parameter's default value.

There is some reference to mode 0 in the resulting dialog box:

Notice I have had to manually add default value text descriptors since there is no clear mechanism to reset to factory defaults.

This is IQANdesign 6...8136, MD4-7, the behavior of the simulator and the device are consistent.

Automatically clear 'no contact' error

Kevin 2 years ago in IQANdesign updated by Chris Litwin 2 years ago 1

I have a system that wirelessly connects an XC21 to MD4 and occasionally it drops connection momentarily. The time the CAN is down is very brief, only ms and it reconnects and communicates again after the disruption.

Although the module reconnects, it leaves an error on screen that the operators have to clear. Is there any way of either extending the delay for displaying the message (assuming there is some damping built in the firmware) or clearing the message automatically, or perhaps even switching this message off?

pressure units

Andy 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 4

Being relatively new to Hydraulics and IQAN It seems to me that most experienced folk in that field talk pressures in terms of BAR and others who maybe more peripherally involved use PSI. In my world that means that teh engineers/mechanics/fitters etc use bar and machine operators tend to use psi. As such on most of my HMI designs I have a slider/switch/parameter that can toggle between the 2 so that who ever is using the machine can see their pressures in their measurement of choice.

The calculation between the 2 is not complicated, nor is the building of a structure that allows you to easily swap on the display the visible output between one unit type and the other.....but it gets old having to put multiples of those same building blocks in place to do the conversion and support the visible flag for multiple pressures etc and it makes HMI design a drag as you overlay mutiple gauges etc....

So I was wondering in the (sometime) future if the definition fields for a device like a pressure sensor (but in effect any device) could support multiple measures and either output in terms of a separate output channel for each measures or use an input channel to define which of these comes from a single channel output... For example an SP035 could have  definition 1 as min 0, max 35, unit bar (just as it is today in design) , and definition2 as min 0, max 507.7, unit psi, being effectively the same thing. The downstream math channel or internal digital that does the calculation/ manipulation could access the device choice channel to modify whatever is being done to account for the unit values differences

If the same input channel that determines which device definition output to use was also available to display devices we could also have multiple scales on a single gauges etc rather than multiple gauges that are selected by a visibility channel.

I know its late Friday afternoon as I post this and my brain may have exceeded its weekly whirring amount....Is this something people think could be useful or should I just shutdown for an afternoon beverage earlier in the day :<)

initialization power reset

akira IQAN 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 2

i have an initialization function group that can change the baud rate, but i need to manually turn the iqan MD4 on and off for it to take effect. is there a way to do a soft reset through iqan design?

Countdown without for and while loop

Sander Sermus 2 years ago in IQANdesign updated by Thomas Moberg (System support) 2 years ago 3

Hello!

I would like to program the following in IQANdesign but seems to be difficult (or I am just rusty, been years that I needed to program anything other than Python :D) without a "for" or "while" loop:

when I push the increase button, it will increment by X%

when I keep holding the increase button for Y ms then it will increase Z%

when I push the decrease button, it will decrement by A%

when I keep holding the decrease button for B ms then it will decrease C%

I would like to keep it in Qcode, but maybe it would be better to use channels?

Best regards,

Sander

COUT PWM program entry does not match physical output

Phillip 2 years ago in IQANdesign updated by Gustav Widén (System support) 2 years ago 1

Hello,

I am using IQANdesign 6.08.25.8210. 

I am programing a MC43FS.


The data sheet lists the following frequencies for the COUT.

PWM frequency, FDITH (Hz) 71, 77, 83, 90, 100, 111, 125, 167, 200, 250, 333, 500

The data sheet and version Publ no MSG17-8413-IB/UK Edition 2022-11-16


IQANdesign allows me to enter an integer value range of 71-500.

I connected an oscilloscope in parallel with a coil to see what the outputs of the various inputs would be.

Please see the results below.

Inputs seem to round up to the next listed frequency.

Exceptions:

                   143 is not a listed frequency.

                    Input of 143 does not output 143. The output jumps to 167.

                    Input of 167 does not output 167. The output jumps to 200.

I did not test every value. Other exceptions might exist.

I cannot find any documentation that explains what inputs result in what outputs. 

I hope this helps the IQAN team.

-Phillip

Kevin 3 years ago in IQANdesign updated by Thomas Moberg (System support) 3 years ago 1

We are re-visiting a project based on the version above with an MD3. We have later versions of 2.x but I don't want to update the firmware, can anyone provide me with a link to download this version of IQAN design please? The earliest version I can find available to download is 2.63.

Cannot Unlock a Function Group

Dragos Popa 3 years ago in IQANdesign updated by Gustav Widén (System support) 3 years ago 5

Hello,

The architecture of our company's vehicle was made by another group originally. That group made some function groups and then locked them. To unlock them, usually, you right click on said function group and use the unlock tab. However, it does not appear like we can access that function as seen in the screenshot attached.

Is there a way to unlock a function group or gain access to the unlock function?

Information output for users

Dmitriy Stupak 3 years ago in IQANdesign updated by Gustav Widén (System support) 3 years ago 1

Hi guys. Do we have ways to show output information for users in MD4-10? For example Logs, warnings, cautions etc from the machine. Do we have only System dialog? As below:

Image 3438


Maybe someone have some examples how to work with it? Becuase I could add only simple text with text formatter.
Don't we have any another tool for output information? Like text view in Android..

Thanks for any advice!
