time left indicator

Hey, I have a DL06 with 8 cascading timers because I need a oven batch time of 2 hours. But I'm using a EZ-T10C-F touch screen and would like it to have a display to count down hours and minutes remaining to show on the screen. How would I code to load all 8 timers accumulation values add them and code them for hours left and minutes left to a V location to display?

An easier way is with 2 up/down counters. One each for hours and minutes.
Use the 'second pulse' to decrement the counter. Your program will be easier to follow and understand, and it will be easy to display on the HMI.
