So many ways to get to the same place. I personally like to use the Station hours, minutes etc with my calc blocks to do resets. I also have a script that I got from a Foxboro Engineer that will even allow you to select a day of the week 1 thru 7. Use these all the time with calc blocks or accumulator blocks. You could also make the operator dual enter the value from an overlay that would ask him if the value is correct. Don't think that there are right ways or wrong ways. just maybe some better way, just as long as it works. Good luck Troy **************************************************************** A lack of planning and communication on your part does not constitute an emergency on my part!
