Let us that are going to school for it have your job when we are done and those that are already doing this kind of work keep their job. Figure it out on your own and if you have no idea what any of these are below then you shouldn't even be messing with this stuff. Age will get you the job before I do when all you did was boost your grade by being book smart and getting a great grade on mid terms and finals (Gotta love when lab tests come up and you book weenies fail it). I don't want to be competing for a job with young punks.

Times are not given and arrangement of outputs not given because you have to learn this. Plus having my own controller set up at home (hint hint to you that are taking an automated technology course). Exercise 1-Traffic Control using 3 Lights From the Simulations Menu at the top of the screen, Select the Traffic Light Simulation 0:200 0:204 0:2/01 0:2/05 0:2/02 0:2/06 Using your knowledge of cascading timers, develop a ladder logic program which will sequence a set of green, amber and red. Using LogixPro and your previous labs as a resource, implement a traffic light controller. I would like to thank this site for not giving answers, I wasn't looking for an answer to this age old question just a few ideas to put me on track and this site was perfect to help me in that. The lights can be controlled using the outputs shown in the. I did it in under an hour and my final outcome is nothing like the standard traffic light program below since it requires additional timers for the red and how you incorporate them and tie them into the other colors. Do your studying, read the ideas in here, don't put sheeeet off to the last minute and you will get it. This delay changes this whole outline completely. Exercise 2: When depressed, the crosswalk push button will cause the appropriate Walk Sign to be illuminated at the next occurrence of a Red to Green transition for the appropriate direction. Mind you people out there looking for this answer, teachers are getting smarter and adding in a delay on the red lights before the opposite green is coming on. Exercise 1: 1 second period (delayed green) with both directions having only their RED lights illuminated. Old topic but if you are studying PLC's you should be using an updated text book which gives you your answer in chapter 7 and I won't tell you what book but will give you the outline below.
