Hi, I have gone through the first set of online training and I am working on the traffic light project. I think I almost have it but I am stuck in making the program cycle back to the begining and start over. Is there a 'cheat sheet'/example of the finished project I can look at? Or can I post/submit somehow for others to look at/critique/offer suggestions? THANKS, Sid

Hi, Since you are enrolled in the stage 2 training, you can submit programs to our instructors once a month as part of the program. You can also submit questions to the private training area of the forum if you would like. You can send your program via email to our website email or send a question via our contact page. We can get an email address to you from there so you can send in the program.

Hi Russel! thanks for your reply. I want to first say that I really like the course so far! you do a great job of explaining concepts and processes. sometimes you will burn through a concept quickly and i think-"uh oh, what did he mean" but then you come right back (almost anticipating my questions and describe things in more detail, or with an actual online example and evrything becomes clear. So, THANK YOU!

Regarding the traffic light project... I pretty much got it figured out but, I am not 100% sure that it meets all of the (your) criteria to be a "good" program and I was hoping that I/we could discuss my approach. I understand that it is a relatively simple task but, as you know, in PLC land there is "more than 1 way to skin a cat". I would rather not use up my 1 program submittal since I would like to try and save it to submit the other bottling plant project which seems more complex and i will probably need more help there. As I said previously, is there a documented finished version of this project that is available for us students to review for accuracy?

Also, fyi, i think there is a mistake on the instructions/parameters for the Elizabeth ave lamp outputs (they are all listed as red lights). Using the Kings Dr. patteren as a template,I changed it in my program but you might want to change for future students. Also, I created the program as directed but noticed that the logic did not truly replicate a 'real' working traffice light. What I mean by this is that the When the program starts Kings is green and Elizabeth Ave is red. When Kings drive changes from Green to Yellow, none of the lights on ELizabeth Ave were energized and Vice versa when Elizbeth changes from green to yellow-should that condition be addressed in the program?

Thanks for your help-Sid

BTW- I did try to post in the registered user area but for some reason it does not allow me to create a new thread-am I doing something wrong?

thx!

Thanks for the feedback! I appreciate the nice comments.

We dont put out an example of any of our projects. That always ends up getting in the way of the student more than helping. It might be worth while, I guess, to put out an example program different from the projects we require our students to perform. I'll think on that. As it is, I really suggest you go ahead and submit the program for review. We dont just review whether or not the program just works - thats the easiest part. Program organization, documentation, methodology, etc are evaluated and commented on. The easier the program sometimes the easier this stuff is to point out to the student also.

Yes I see the mistake on the light program. Tough to get a break if you are sitting at the light at Elizabeth... All red all the time. I just cant believe you are the first to notice or to bring this up!

Dont post to the registered user, but the training section at the bottom. Let me know if there is a problem there. Hopefully all your posts wont end up red or something.
