hello
am trying to program a plc to work according to days
the idea is like this
for example lats say it is about heat control
each day or few days have different heat values
like this :
day 1 it should be 20 c
day 2 it should be 30 c
day 3 it should be 33 c
day 4 it should be 32 c
day 5 it should be 26 c
day 6 it should be 35 c
day 9 it should be 28 c
the problem is how to make an accurate day counter
and it should still count even when the plc is off
as the days values
am in day 2 the heat set should be 30 c
for some reason the i lose electricity for 3 days
when it comes back and the plc turns on
it should know that we r in the day 5 and the heat set should be 26 c
so plz if any one can help
tell me what to do
am using dopsoft and WPLSoft 2.41
with thanks
