Programming multiple NI-9402 Channels Using cDAQ-9178, need help

i need to program 13 channels with a vector file and have it loop over and over.

Im using a cDAQ-9178 with 4 NI-9402 modules in it.

Labview v20 and NI Max v20

The program will work as long as i only write to 4 channels on the same module and cut my vector pattern down to just 4 channels.

But if i select 2 channels from 2 different modules it want work.

 

I have not read anything that says i can't control multiple NI-9402 at the same time.

 

I need some help.

thanks,

les

Could you please post the code in LV 2016 version, you will cover a broader audience by doing that.

When it "don't work" which error do you get?

You get an error, don't you?
