Help with Logic

I have the logic below in which I am trying to switch all inside lights on when there is an alarm (Comfort) and it is at night, and for the outside lights to flush, while the alarm is still on.

When there is an alarm (at night), all inside lights turn on, but the outside lights do not flash at all. Can anyone tell me what am I doing wrong?

---------------- Start of logic -------------------------------------
once (GetCBusState("Network 1", "Security", "Alarm State") = ON) then
begin
if (darkOutside =true) then
begin
SetScene("All Inside Lighting Scene");
while (GetCBusState("Network 1", "Security", "Alarm State")=ON) do
begin
SetLightingLevel("Perimeter Lights", 100%, "0s");
Delay("00:00:04");
SetLightingLevel("Perimeter Lights", 0%, "0s");
Delay("00:00:01");
end;
SetLightingLevel("Perimeter Lights", 90%, "0s");
end;

end;

----------------------------- end of logic ------------------------------

Logic and once

I think you will find it is because you have nested your 'while' operation inside the once statement.

Once is a very handy 'non standard' process for automation. 'once the condition is true it has to transition not true then true again (once) before the following actions will be executed.

You might have to write additional code to set an alarm flag (boolean variable) then send commands (if) whilst the flag is true. Don't forget your delays and good code to reset the alarm flag after a period of time or when the alarm resets.

PS . Do I get this right - do you have three Tags inside the once condition. Does this actually compile ?

 

Do the outside lights go on ?

Try a delay of 2 or 3 seconds and see if it makes a difference. It may be that the lights are flashing off for such a short time that it isn't noticeable.

 

yes, I think so. With a scan based engine like the PAC you would be much better programming it using PLC mentality and using a timer you check on each scan to do timed actions based on events.

 

yes

Logic code in other modules will continue to run.

 

The outside lights remain on the whole night. When there is an alarm, I would like them to start flushing and once the alarm is off again, the outside lights should remain on.

The inside lights do turn on

I tried the same logic without the do loop and alarm if condition and it works.

 

That is what I wanted to do in this case, that is keep the lights flashing until the alarm stops. Then turn the lights back on (in the logic).

 

Yes it compiles.

 

It may be best to send your project archive into Tech Support so that they can duplicate the problem and find the cause.

 

Did as you suggested, alarm went off last night, still no flashing .....

 

For what its worth,

Write the Test before you Write the code.

When my logic is not working, I always write code to show where the logic is falling over. This is usually in the form of Screen indicators, and monitors on all the variables involved.

Hope that helps.
