Error occured at CTRL NI-CAN action

[Bunny3]

Hello,

This error is showing repeatedly though I connected power supply to the LIN Interface Hardware? Can anyone tell me why is it showing so?

Hi Bunny,

double-check power supply of the LIN port. Triple-check, if needed!

When power supply really is connected with the correct pins: check your CAN/LIN interface for correct operation…

Hi GerdW,

Thank you for your prompt Reply. I checked lot of times whether power supply is connected well But when I clicked on continue Option repeatedly this error is not showing and I am able to use then afterwards. But I just want to know why does it happen like this.

Regards

Bunny

Hi Bunny,

But I just want to know why does it happen like this.

We don't know your VI(s) nor do we know your hardware setup: See for yourself to find the cause of the problem!

But when I clicked on continue Option repeatedly this error is not showing and I am able to use then afterwards.

So this problem only occurs on startup? Then it vanishes in later calls?

Then you don't have a problem at all: just handle that first error programmatically!

(Maybe it helps to power up the LIN port earlier? Maybe it helps to put a wait statement before that ncAction call?)
