Out Of Memory MD3
These are the memory specifications of my system, when I try to send the project to my HMI, it goes into safe mode with the following message Out of memory, could anyone help me to solve this problem,
thank you

no reply from IQAN connect server?
We have tried accessing a machine remotely and have the following message, is this a problem a Parker end? We have tried 2 PC's and have the same message.

LIN compatibility ?
Hello,
Does IQANdesign support devices which communicate using the LIN protocol?
The aim is to use this device for standard parameters such as voltage, current and charge.
An example to illustrate this would be useful.
Thank you

Test connection to system before project check
Sometimes (due to our own fault) we forget to check the system is either connected to the computer properly or ignition is switched on. Our projects typically take a good 5-10s to check, then when clicking send it errors saying system not connected, forcing us to re-select send project and go through the project check again. It does not sound like much time, but can sometimes be frustrating waiting for it top check again.
Is there a way of alerting you (after selecting send command) that the system is not connected so it doesn't close project check and force you to have to resend, then check the project again? Just an idea, other people may also find this useful.

Error, stopped critical
In a new controller we tried to load a program, but did not succeed completely. Then the LED of the controller blinks 4 times red and 1 time yellow followed by 17 times yellow. And when we try again to connect, the master module can no longer be found. Is there something we can do?

PWM frequency for L90 valve
Hello sir,
I am working with a Parker L 90 valve. The recommended PWM frequency is 100 to 125 hz. I wanted to understand the reason behind.Does this has anything to do with the Resistance/inductance of the coil ? Like the rise time of current in coil ?
If I run the coil with high PWM frequency say 2000 hz , will the current ever reach to maximum (I = V/R) ?
Is the recommendation of 100 hz only for avoiding switching losses or it has to do with performance as well .
Thanks

Hello.
In other systems you can maybe set the PWM frequency and dither frequency separately.
You would add a small oscillation (the dither) on top of the PWM to avoid stiction and hysteresis.
In an IQAN system the PWM frequency is low enough that it creates an oscillation by itself, thus the PWM frequency is also the dither frequency.

SV Camera Lag Issue
Hi,
I have integrated the backup camera on our vehicle and I came across a lag issue with the camera and was wondering what the root cause was. Please see attached video (https://www.dropbox.com/s/0wgs5htr8moqyss/IMG_4580.MOV?dl=0) . Maybe you guys could help.
I chose to go with a 50 ft M12 cable, and there is not much loose considering the fact that the box is 20 ft long.
( https://www.digikey.ca/products/en?keywords=wm15300-nd).
I played with the following parameters in IQAN for the SV Camera
- Enable HDR: No
- Max bitrate [mbps] : Toggled between 1 and 20. At 1, the image is really pixelized as on the attached photo. At 20, there is a lot of lag. The current setting is at 4, and the image quality is really poor with some lag. Considering the fact that this camera will be used to backup to a shipping dock, the small lag is a big concern for our customers.
- Dimensions: I toggled between Wide 800x600and Narrow 160x120 with no interesting improvement.
Is there something here that I am missing? My though is that the wire is too long, but it is impossible for me to shorten it.
Best regards,

Limit Event counter Channel (ECNT)
Is it possible to limit an Event counter channel with a maximum and a minimum value?

Hi Giel, the event counter channel is typically limited in the "Increasing" and "Decreasing" columns when using the Object list method. Similar limits can be used in the Qcode method.
As an example:
In the increasing column:
A: Button 1 Press (Single object)
B: ECNT<10
C: A and B
This would limit the event counter channel from increasing above a value of 10

ID-TAG
Do I have to connect the ID-Tag to my Master module even though I'm using only one master module MD4 and one expansion XA2 will be connected to it, can anyone help me with this?
Thanks

From the MD4 instruction book it states an MD4 always needs a tag. Without a tag it will start in safe mode.
