New programmer-programs that conflict with each other-????

[62vetteefp]

I made up my first light programs and they seem to work.

 

I have the two programs below controlling one light. To me they should conflict because the Else statements can happen at the same time as the If statements in the opposite program.

 

To me they should have a conflict. How does ISY handle this?

 

If

From 5:30:00AM

To Sunrise (same day)

Then

Set '24.82.CB.1 Library glass' On

Else

Set '24.82.CB.1 Library glass' Off

Turns on and then off library lights in the morning

 

 

If

From Sunset - 10 minutes

To 11:00:00PM (same day)

Then

Set '24.82.CB.1 Library glass' On

Else

Set '24.82.CB.1 Library glass' Off

Turns on and then off library lights at night

There is no conflict between the two Programs. The first Program Else executes at Sunrise and turns the device Off. The second Program Else executes at 11PM and turns the device Off.

 

Even if the two Programs were physically running at the same time only one Program can actually be executing statements at any given time. The ISY would send the commands to the device through the PLM which can only handle one Insteon command at a time.

 

If I have missed the point please post back.

My issue was that the else OFF is all times other than the defined IF times.

 

Program one says if it is not 5:30 am to sunrise then lights OFF.

Program two says if it is not sunset to 11:00 then lights OFF.

 

So during 5:30 to sunrise program one says lights ON while program two says lights OFF.

AND during sunset to 11:00 program two says lights On and program one says lights OFF.

 

What I think you are saying is that the program only executes during the IF time period stated. At sunrise time the lights go off and then the program does not run again until 5:30 the next day.

 

right?

 

Merry Christmas!!

You are absolutely right. A Program with a From/To time trigger is invoked twice. The Program is triggered at the From time, the If is True so the Then clause executes. The Program is triggered at the To time, the If is False so the Else clause executes.

As Lee said, you are right. The concept here is a trigger. ISY programs that are true or false are not enforced unless they are caused to run (triggered). So in a program that is a from/to program, there are only 2 triggers, the from and to times. At any other time it is as though the program doesn't exist.

 

However, adding another clause in the program could change things.

 

If

Time is from 8am to 10 am

And

status of device x is off

Then

Do something

Else

Do something else

 

Now realize that every time device x changes status the program will be triggered and the truth or falseness of the time being between (or not between) 8 and 10am will be important.

 

Also there still would be no conflict with another program that also has time definitions on a device if it is idle (not being triggered). There would only be a conflict if 2 programs had the same triggers and different outcomes.

thanks.
