Hi All
         if i have a valve saved to a marker is there away of resetting the value to 0 at a specific time. for example count water usage from april to september and keep the value visible and then reset it the 1st of jan every year. Cheers

Use the RTC. By comparing the date/time you generate a reset edge like this:

IF (RTC = target time) THEN M01:= true; END_IF

IF (RTC = "target time") THEN
   MW1:= 0; END_IF
To reset the flag word use the RTC including seconds, then the word 1s is written with zero.
