Why is and is not received?

I see constructs like below in many many programs.

Almost all I think. What is the strategy - why test to see if something

is both on and off at the same time? Evidently, things can happen that

present both conditions near simultaneously?

 

 

Program X-10 D4 Status

If

X10 'D4/On (3)' is Received

And X10 'D4/Off (11)' is not Received

Wouldn't the else clause run anyways if no D4/on were received?

Why have to explicitly test for it?

 

Please pardon my denseness....

Enjoy your weekend Lee, Thanks.

No.

 

"If X10 'D4/On (3)' is Received" would be triggered only by reciept of an "on" command. Bright, Dim, and Off would not trigger an evaluation of the condition and no "false" evaluation would ensue.
