I am currently working on a project that totalizes raw material charges on a 24 hour basis, each morning at 8am the current totals, are copied to storage registers, and then the totals are reset(zeroed). This is using an existing 1747-L542C and a RIO Panel View 1400.
The Panel view will display the current totals, and the stored data from yesterday.
My question is if this needs to happen every day at 8am, how do I handle day light savings time? I know I can access the PLC and change the time twice a year, but was hoping someone had already had to deal with this, and could give me a jump start. I'm not sure it's possible, since the time shift doesn't happen on a specific date, it is usually the first or last Sunday of the month.
thanks,
Ken
