Your M-series board only has 2 counters -- that's why you can't perform 3 tasks. Here's at
least one other idea you might consider.
Consider the task where you want to count rising edges of a particular signal. You can probably
do that by wiring to a line on digital port 0, and making a DI task based on "change detection."
You can then just keep track of how many samples have been taken which will give you the
same number as counting the edges with a counter task.
