What is the startup status of the timers in the POWR1014?

All of the timers in a POWR1014 or POWR1220 default to a stopped state at power-on, so there is no need to manually 'reset' them before triggering them. Additionally, the START TIMER instruction in Pac-Designer's LogiBuilder sequencing language will always reset a timer before starting it.  The most common situation in which you need to 'manually' reset a timer is if it is used in a watchdog function operating concurrently with a LogiBuilder sequence or supervisory logic.
