I use an SBUF in SIMPL for this, which gets enabled after ~10 sec on boot.
That way, the initially 0 analog signals don't cause switchers to change
sources before the old settings get recalled from memory. The SBUF blocks
serial and analog signals that would otherwise go to devices. Also, a BUF
signal prevents the program from triggering motion-detector logic for
contact-closure-output detectors, which have inverted logic due to the
pullup resistor.

The only SIMPL+ 'event' that will automatically run when the program
is initialized is the Main, so if your Change is running at bootup
it's because something is causing the analog connected to the input to
propagate a zero at bootup (IE: the issue is in your SIMPLWindows
code).

There's nothing wrong with encapsulating the output calculation in an
IF statement to prevent a transition of the output you don't want, but
it won't do anything to prevent the unnecessary SIMPL+ thread from
being generated.
I'd concentrate my efforts on preventing the input analog from
propagating at bootup.

Subject: [Crestron] Simpl + Change Analog


Hi All,

Have a issue that has me stumped.
using the below

Change Analog_in
{
Print("Analog_in %d &#92;n",Analog_in);
Level$ = IToHex(Analog_In);
}

When program initializes it enters this module and outputs unwanted
code eg sets hex levels to 0. (turns off amp's) Is there a way to stop
this happening?

my only way of fixing this currently is to do a feedback loop eg

Change Analog_in
{
Print("Analog_in %d &#92;n",Analog_in);
if (Analog_in <> Current_Level)
{
Level$ = IToHex(Analog_In);
}
}
