Is it possible to monitor spi using Arduino(with labview)

Seto311_0-1690462613903.png

As shown in the figure above, I would like to make VI that only monitors the SPI communication status between PLC devices using Arduino.

I wonder if this is possible

 

I made it VI but it doesn't work at all.

I have confirmed that communication between PLCs is proceeding normally, but I can't see any data word in the VI I made

I don't know what the problem is.
I need your help thank you god bless of you

Hi Seto,

How should we locate the problem when you don't attach your VI?

 

Suggestion: use the Arduino to monitor the SPI communication using the ArduinoIDE. Send the detected data to your LabVIEW computer using the (virtual) serial port of the Arduino and read it using VISA in LabVIEW...
