pressure units
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
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
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
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.

IQANDesign 2.08.8 download link
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
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?
List of elements or table etc
I have some warnings that I should show to user when I receive them. Is there a way to scroll any list ot another way with list of elements? If I receive, for example, 10 elements but I can show only 5 on the screen. Especially when I have different types of messages: warnings, causion, notifications...
Should I only add some hidden elements and show them in time? But it will be strange way... Especially when I have many different elements
Thanks for any advices!
Information output for users
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:
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!
Slow MD4-7 display and logic issues when cycle utilization is higher than about 55%
I would like to reduce my cycle time if possible, though once cycle utilization gets above approx. 55%, display pages take longer to load and logic that requires precise calculation order starts to have issues. From what I can tell you should be able to safely run up to 80% utilization without issue. Any suggestions or fixes would be appreciated.
Working with three buttons to change state
I have 3 buttons to change condition of the boat: 1 2 3. So when I press one button then it should be disable to press it again but I can press two another buttons to change the state.. What is the best way to do it, guys?
For example these 3 buttons
