Baffled by Programming Logic

[David Rabiner]

Hi, there.

I've spent a lot of time on this, and I'm baffled. I'm working with the 737

file.

I can't figure out why the source1off and source2off lights are not ON when

I start up the program up. I know the light should, of course, be linked to

the battery, and I know it acts properly, but I can't figure out why.

The line reads as follows:

source1off = (elecbus1 = 0) and (apubus = 0)

I monitored all three using FSUPIC, and I discovered that all three are
cleared when the program starts cold and dark. That doesn't make sense to
me because if elecbus1 and apubus are cleared, then source1off should be
set. When I switch on the battery, source1off gets set. However, I can't
see any link in the code between source1off and the battery.

I'm wondering if the textlightboxes are connected to the battery somehow
someplace else? If so, where?

Warm regards,
David

Hi David,
I have to correct.

>The line reads as follows:

>
source1off will set to 1 (ON) if one off "elecbus1 or apubus" is set to 0
(OFF).
It will set to 0 (OFF) if elecbus1 and apubus are ON or if Battery is OFF.

Best Regards
Thomas Richter

They are connected *inside* of pmSystems, otherwise you
would have to have a *very* long list of lights with:

if batt1 = 0 then
this off
that off
theother off
yetanother off
endif

Thus in other words, you want the source lights to be on
even when the battery is off?

Thanks, Enrico. I appreciate that.

It's not that I want textlightboxes to light when the battery is off. I've

just created boxes without making that assumption:

textlightbox = this-condition AND that condition AND batt1

Knowing that the textlightboxes are already dependent on batt1 (or
standbypower, I'm guessing) will streamline my code.

Do you have other internal conditions that might be helpful without spending

a lot of time or compromising secrets ;-) ?

Warm regards,

There is nothing secret about a light being off when the
battery is off without putting you through the trouble of
switching them all of individually. I hope you do see that.

Can't think of anything, but perhaps you will find it? If
you do, just ask. If it is urgent, send an e-mail to

Ciao

Enrico

Further to my reply, there are two variables that handle
these things internally.

mainpwr - used to tell pmSystems whether lights or
light-based outputs can be handled ... normally it would be
controlled by the batt1 variable

basepwr - used for the digital texts and gauge needle
movement

Thus if you want to handle all light outputs individually,
set mainpwr to on all the time, and add the code so that the
lights are switched off. But this is easier I think.

Thanks, Enrico.

I think I might have seen that in the docs. ;-)
