Variable rollover with Labview (suggestions?)

I'll consider that, and see what I can do without too much hinderance to modification.

It sounds like you might be looking for the "modulus" operator. I'm not a LabView expert, but I did find this in my googling - http://forums.lavag.org/Computing-mo...w-7-t8550.html

Thanks, but no. All I want is an artificial rollover. The modulus operator was just another way of getting it done

There are many ways of doing this.

I'd start along Eric's lines of asking more questions. The easiest way to detect overflow is before the operation that causes it. Before adding or subtracting the delta, determine if dX is greater than the boundary it is approaching. If so, do some wrapping code.

Key operators that may be handy are the "Integer Division", which performs the modulus operation, giving IQ and R. There is also the "In Range and Coerce" node.

Have fun.
