AOI help

I am trying to create an AOI block to count the number of starts a piece of equipment does in an hour. I have some of what I think will work attached. The issue is my output number gets reset and never held. I want the counter to reset but no the holding register.

Any ideas on what I am doing wrong.

thanks in advance for the assist.

The problem is on rung 3. You're copying the accumulator into START during the minute 0, i.e while the time is between 0m0s and 0m59s. So when you reset the timer, acc=0 is copyed into STARTS.
