NI 488 SRQ stuck in on position

[Trainee123]

Hello,

I have a CAN interface from Peak System that I used to communicate between Labview and a motor controller by sending CAN frame. Every time I send CAN frames through Labview function/VI, I got an error message after some time which says that the CAN bus is in "bus-off" state and the reason is that "Labview: Image not found. NI-488:SRQ stuck in on position".

I don't understand this error message. Can someone help me please?

How are controlling the interface? Is it a dll of some type? The error code sounds like it's coming from something other than LabVIEW. Please provide some details on what exactly you are doing.

I am executing a CAN Write function developped by Peak System to send CAN frame to the CAN bus in a while loop. But in the middle of the execution I got the message. In the while loop I put a 100ms wait function.

That does not explain anything. Exactly what is the function doing? Look at the block diagram or post an image of it. You'll probably have to contact the vendor to see what that code means from their driver.
