How to combine multiple digital inputs for reading?

[RUR]

Hi Fellow Labview users,

I just started using LabView and I'm very new at it. I know the basic understanding of how it works and got something to work but I need it to be more efficient. 

I'm using Measurement Computing's USB-DIO96H DAQ, which has 96 digital inputs. I use the DAQ to acquire relay activations and record the number of times the relays flips. 

Basically I created one digitial input read, and then copy & pasted it 95 times... it works but I know this is not the best way to use LabView.

 

How can I change the digital input (dev0/1stPortA/Di1) to be multiple so that it iterates through all 96 channels without copy and pasting the same diagram over and over?

If it was an NI device, the syntax would be something like DI0:7 for the first 8 lines. Not sure about your device. What does Measurement Computing say? That is who you should be asking if the help doesn't explain.

Thanks for the quick response! Yes, the input does allow me to do multiple channels with 0:8. 

However on the output side I tried to create an boolean array to scan through the channel lines but LabView gave me an error on type mismatch. (Type of source is boolean, sink is 1 D array boolean).  What is the correct way of displaying the multiple channel? 

Cheers,

Leon

Do you have the correct polymorphic instance for the read? Again, for NI, it would be an NChan Read. There should be a similar choice if I recall correctly.

Thanks Dennis, That was very helpful 🙂

ULx's read VI has 1 D boolean that allows me to display the N-Channels in arrays.  Now I can delete the rest of the redundant lines and use that one N-Channel read.
