Ive bound the cycle running output from a piece of equipment to a timer to track run time. at the end of the day I transfer the timers value to a memory tag and reset the timer. Ive noticed the last couple days the runtime being reported has been getting worse and worse. Im watching the value of the timer and it now seems to be incrementing at half speed. is there a reason the timer would not be reliable? is there a better way to track run time?
