Code for newbies

Due to the fact I have received a couple PM's in the past few weeks, from people (real world technicians and engineers, I'm sure), claiming they need help writing code for a couple projects; I have taken time out of my busy schedule to assist them.

I have written a program to control any model of garage door opener, this same code will also run a set of stop lights. There's even a subroutine that takes care of carwashes, so if you're ever called, you can progam one of those too.


Oh, one last nugget I forgot about, I also included a popup message that will let you know if you're downloading the program to a unitary, modular, or rack mounted PLC.


PM if interested.

Greg,

I see you've left the elevator problem up to me....

Ok so here it is..

  UP BUTTON                UP MOTOR CONTACTOR

----||---------------------(   )



  DOWN BUTTON              DOWN MOTOR CONTACTOR

----||---------------------(   )

I'll add in the logic for an oven.

    Too  

    Cold      Burner

Man, we're close to covering any immaginable controls situation.
We better be careful, or we may all be obsolete by the knowlege contained within this thread.

Mike and Jim, thanks.....I'll be sure to add those two functionalities in my next rev.

You forgot the repair technician's favorite which any competent programmer should have included

             Broken                      Fix Itself

---------------| |-------------------------( )

 

Why not just add a "DO ALL" button on the HMI?

I love those bits of Code...I wonder what my boss will think when ...and I will, include them in my next project.... I'll let you know how it works out...
