hours of the day

[maciek]

as always this is going to sound dumb but
i would like an output to be on from 8pm(20)to 6am and another one from 7am to 7pm(19)

[franji1]

Is this two different outputs?  The second one is easy

STRGE $Now.Hour 7
ANDLT $Now.Hour 19
OUT C42

The first one is easier if you think about when you want it OFF, between 6 and 20, then invert using the NOT contact.

STRGE $Now.Hour 6
ANDLT $Now.Hour 20
ANDNOT  // inverts power flow; this is the triangle contact with a small circle on the end
OUT C43

[franji1]

Or just

STRGE $Now.Hour 20
ORLT $Now.Hour 6
OUT C43

 

[maciek]

thanks you are the man

[Sayles]

The first one is more difficult, but do you get any benefits for using that one?

[Bolt]

No "benefits" to the more difficult rung.  I suspect franj1 thought about a cleaner way to go about it a minute later.

[PLCwannabe]

How about if these outputs need to be on between 2 different times including minutes? E.g. 6:24  to 12:54 but not on Mondays and Fridays. It becomes a little more difficult and messy. That is why a scheduling structure would be great for Do-more. 

[Bolt]

I will sometimes create a variable HHMMSS, (Hour *3600) + (Minute *60) + Seconds, creating a time code. Then you can use comparison statements to a single number to enable desired actions.
