slotted opto sensor

Hi all
I am having trouble with a project I cannot seem to find a solution. I need to sense if a reel has stopped turning via a slotted opto there is a flag on the reel. When the reel stops the flag will be in the sensor and the sensor will be high. However as the flag is always passing through the sensor it would have to sense the long delay at the end and not the shorter pulse's. I have tried to use "count" but it will trigger on the leading edge but there is no low signal as it has stopped.
hopefully

pulsin instead of count? Any value other than 0 (timeout value) means it's still spinning.
