Re: 100% CPU Utilization Using 10ms Periodic Task

I was asking just to see if there was a bug or something that could be improved for the future.

One such thing is to make the errors be on the front page instead of the second page. Other things can be done so that the errors or number of errors are more obvious. The other issue is that the current error routing is too slow and often causes watchdog issues. I believe that is fixed for next year along with a deploy issue that it can sometimes cause.

As for the string dictionary that was demonstrated. That is a great way of preventing inconsistent spelling. I'm not sure if it is necessary or good for all teams, but if you have the skills to make the subVI and update the typedef enum, it is a great solution. The overhead of the subVI should be quite small. Making it a subroutine would shrink that by quite a bit. Making it be inlined will, as pointed out, should make it disappear entirely as the compiler substitutes the code, then propagates constants, then removes unreachable code.

Re: 100% CPU Utilization Using 10ms Periodic Task

We are not really concerned with the efficiency of the string dictionary as these are only called once at the entry of Begin, Periodic Tasks, Finish and Disabled if they are motors.

The references returned are stored in the Shift Register for the duration of the execution. With our rule of only a single Get Reference allowed, it has not been a problem with speed, just planning.
