CRC Rule A
I need a CRC check described as Rule A as seen in the table. I'm not sure if it is possible at the moment and how to make it work. I think it is different than the standard options in iQanDesign.
Can someone help me please?




Diagnostic bus with J1939 bus
We are trying to reduce the need for an MC4X in our system and just use an MD5. We are controlling a CAN prop valve, a CAN on/off valve and a CAN joystick. I've seen that you can share the diagnostic bus with a J1939 bus. Is there any limitations to doing this other than high traffic?
csv file for parameters
could we get a csv files for all parameters? I would like this as an output so we can quickly check with software that all parameters are correct. a quick check in the field before techs leave a site !
multiple actions on display button
Is there any way a Custom Button/Symbol Button is able to control 2 channels, like when property 'Action' is set as -Measure group-, it also can act as an -VDIN- ?
In my case I'd like to show the Measure group, and at same runtime enable a channel (Memory Utilization)
so it will be readable in Measure Group)
Maybe a future idea ?
Copy Paste Variant Options
Ive been experimenting with variants to make code reusable between different systems. It would save a lot of time if I could copy and paste options as well as whole option groups.

Menu navigation
I'm coming back to using IQAN Design after a long period of no exposure to it. Currently I'm trying to implement a menu navigation system using external buttons (digital inputs).
The menus can be thought of as being in a circle - as the 'right' button is pressed the screens navigate around the circle to the 'right', wrapping around from the 'last' screen back to the first in the circle - same when going left. I implemented this a long time ago on another project but for the life of me I can't remember how I did it.
I've tried using Event Counters, and Integer math, but I can't get the logic to wrap bi-directionally. The Integer function isn't retaining the counter values, and the Event Counters can only reset in one direction, if that makes sense. I know this should be easy, but my lack of recent experience isn't helping! Can someone suggest a way of implementing this?
NB - I usually use QCode
