I have 9 tanks that are measured manually and then the measurement is entered into WonderWare and is displayed on the tank graphic. Supervisor wants a time stamp on each tank displaying the date and time the value was updated.
My solution:
Using a data change script, I move the PLC date/time to the Tank date/time whenever the measurement is changed. However, this uses 5 register numbers per tank (Month, Day, Year, Hour, Min).
Is there a way to do this that doesn't use up so many register numbers? I'm running short (about 100 left) and I don't know when I'll be able to stop the processor to increase my numbers. (Plant is a 24hr/day operation)
