ECU MC Toolkit problem with NI-9860 (problem a2l)

[RchB]

The ECU have two ports CAN. It works in the second port

[RchB]

Now I can read values of measurements ( using MC DAQ Initialise and MC DAQ Read), but some values are wrong ( value does not match the expected value). So I use specified address of measurement and Upload.vi to get value, always the some problem (I have the same result as method 1)

Is there any explications ?

Thanks

Do you have your vi setup with two separate threads for talking to the two ports?

The port you open must be the port you Command/Read.  The hardware & software do allow for both ports to be active simultaneously.
