SV Camera Lag Issue

fdube 6 years ago in IQANdesign updated by Gustav Widén (System support) 6 years ago 10

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)

Giel Coopman 6 years ago in IQANdesign updated by Gustav Widén (System support) 6 years ago 2

Is it possible to limit an Event counter channel with a maximum and a minimum value?

Answer

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

Hassan 6 years ago in IQANdesign updated by Chris Litwin 5 years ago 7

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 

Answer

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

Starting and stopping simulate

Ed Schippers 6 years ago in IQANsimulate updated by Gustav Widén (System support) 5 months ago 3

Starting and restarting of a simulation takes a lot of time and after every (re)start it starts in the same view so when you are working on large projects you need to a lot of clicking before you reach the part that you are testing. this is particularly annoying when testing  functions that run only just after boot up.

It would be nice if there was a function that you could do a restart without stopping the simulation and/or a or a function that when a simulation is started the program it stays in a pre- operational state so that you can navigate to the part of the program that you are testing and then start the program simulation.

Unable to get machine logs from MC43

Kevin 6 years ago in IQANrun updated by Gustav Widén (System support) 3 years ago 3

We have a multi master system with 1 x MD4, 3 x MC43 fitted to two identical machines. All 4 modules have multiple logs inside, we are able to get logs from all modules, however two logs on one of the MC43's only will refuse to download when using IQAN Run. Running Iqan Design 5.03. The logs are visible, and it displays how many logs are inside, however when double clicking to show the logs we get a blank white screen while its trying to populate the logs on screen then it times out after around 20 seconds with a message box saying no response from the controller. The controller remains active, no error flashes.


The controllers are not overloaded, and we are talking only a couple hundred logs inside each log, not thousands and thousands. Is there any known reasons why this could be happening? Its the same for both machines we have, so something common between the two...

Password box wont take enough characters

Kevin 6 years ago in IQANrun updated by Gustav Widén (System support) 5 years ago 2

We are using an application created in IQANDesign 5.03.11.5029 and when simulating the application I'm unable to login using credentials i configured within design on IQANRun 5.04.6.4873. Looking closer our password we set in design is 27 characters in length but IQANRun will only allow 25? IQAN Design notes state a password can be up to 40 in length, is this a bug or conflict between different versions?

Does this affect the tablet access as our customers use this length password to login, will IQANRun for tablets also limit the password length to 25 characters?

Directional Pulse Count Inputs

Barnhart Crane 6 years ago updated by Edward Polzin 6 years ago 3

I need 8 directional pulse count inputs... Is there any hope other than using 4 XA2s? Any plans for an IQAN expansion module that can do 4 or even 8  of this kind of input?

I can't find any 3rd party CAN modules that have this type of input. It seems to be all industrial modules.

Invalid context when upgrading IQANdesign 5.03 to 5.04

mdonaldson 6 years ago in IQANdesign updated by Gustav Widén (System support) 6 years ago 4

When I upgraded to IQANDesign 5.04 from 5.03 my project now has 1183 errors, with 99% of them being 'Invalid Context'. I can't seem to find a pattern as to what is wrong with particular snips of code.

Here is one example.
