I found this application (see sippet) which read from all four digital ports and then add them to array and counts 1+ for each time the sum of the array is 0.
I'll like to just check on one digital line. When I change the DAQ Assistans to digtial input from port to line it turns into a boolean. But how do I change the setup so I only compare the one line which propely is 1 or 0.?
If I understand your issue properly, you can just replace the Add Array Elements and the Equal To 0 with just an OR Array Elements.
