Resetable counter

[MikeB]

I am trying to automate communication with a serial port DA unit (Kaye
Digilink).

My problem is that each command I send to it needs an iteration number
that goes from 0 to 9 then repeats from 0. Ie: first command is 1,
next comand is 2, till number 9 then reset to 0 and repeat. How do I
make or find a resetable "counter" to do this? I used the "Concatenate
a String" to break the input string apart but must increment
iterations by hand now.

Searches have found nothing of help!

I have Labview 5.1 & WinME

Thanks,
MikeB

One way to do this is to wire your loop iteration to the X Input of the Quotient and Remainder vi. You want 10 steps so wire a constant 10 to the Y Input. The remainder output will give you 0-9.

Have fun!

Mike,

You could use a shift register, and use a case to put a 0 in the shift
register when it is bigger then 9, but...

You probably have a counter or "i" from a for or while loop.

You can feed this into the Quotient and Remainder function. This is
LabVIEW's MOD function. It devides x by y, and returns the number of times
that it fits, and the number that remains. So:

x mod y => remainder / quotient
0 mod 10 => 0 / 0
1 mod 10 => 1 / 0
2 mod 10 => 2 / 0
3 mod 10 => 3 / 0
4 mod 10 => 4 / 0
5 mod 10 => 5 / 0
6 mod 10 => 6 / 0
7 mod 10 => 7 / 0
8 mod 10 => 8 / 0
9 mod 10 => 9 / 0
10 mod 10 => 0 / 1
11 mod 10 => 1 / 1

The quotient returns the number of iterations, in your case. So you get this
as a bonus!

Regards,

Wiebe.
