Sure, its a little more work for me. but Its worth it. I'll get it posted asap

Ok guys (and gals if any) this is the problem that caused much controversy elsewhere but, Im going to post just the directions for the section that i was having trouble with and Im going to try and give you precise instructions as they were interperted to Me. I would appreciate it if You all would look it over and tell me how far out in left field i am. I tried to keep it as short and simple as I know how (and my know how doesnt go far yet). Here is the puzzle If input 4 is false and inputs 1 and 2 are true then ouput 1 will be true and remain true after either input 1 or 2 is becomes false If input 3 is made true then output 1 will become false. if inputs 1, 2, and 3 are true then Output 1 will be true. if input 4 is true then output 1 will be true, when inputs 1 and 2 become true then output 1 will be false and remain false until input 3 becomes true, output 1 will remain on after input 3 becomes false again as long as inputs 1 and 2 are still true. Real Brain teaser this is....lol here is my solution as screwed up as it may be.

Thanks again I would not want anyone to do my homework thats half the fun of learning, Just need some direction sometimes, and have you all critique my work and tell me of my mistakes and or bad techniques. I'm trying hard to learn all i can. maybe the hard way, getting bits and pieces here and there even some thru trouble shooting at work, wish i had learned this trade before I hit middle age....lol might have sunk in a lot better. and sometimes I think i try and over think whats not as hard as It sounds or seems. but i'll get there. my goal right now is to be able to connect to PLC's and work for trouble shooting purposes and eventually make small changes to the programs when needed. BUT dont worry Im not about to take lives into my own hands without proper training and supervision......lol Thanks you guys for your Help

Hey Bob and everyone else involved, Thanks for all the help, It going ok, finally got that project behind me and have moved on to project 2, an anti-tie-down project, will be glad to post it and my solution if You all want. The instructor for this class is really messing with Our heads I think with the specs he is giving, He leaves so much to be assumed, but yet you are lucky if you can corner him to get more specific info.

Please Look over this it seems to meet all conditions as i know them, Thanks TW It was re-reading your post about latching bits that brought this to mind. It should work as follows if switch 3 and switch 0 and switch 1 are on then output 0 is off. if switch 3 and switch 0 and switch 1 and switch 2 is on the output 0 will be on and remain on even if switch 2 is turned off, as long as switch 0 and 1 are on.

taking it at a community college, what you mean by nothing in writing? if you are referring to the specs for this project, what Lancie posted earlier are Word for Word what is on the sheet. If need be i could scan it and attach it.

ok I wrote this and it does what the instructor wants except, the condition where if switch 2 is made output 0 will remain on even if switch 2 is turned of as long as switches 0 and 1 are still true. but as wher switches 0 and 1 turn it off in the beginning now they are to keep it on......if a one shot will work i cant figure out where to put it. Ok would you like me to post it as it is written example is when light 1 is on y0 is true or post it like it is suppose to read, example when switch 1 (or input 1) is on output 1 is on?

one more shot, and if htis isnt enough info I apologize this step says when switch 3 is on and switch 0 and 1 are on output 0 will be off and remain off until switch 2 is made and will remain on even after switch 2 is turned off as long as switches 0 and 1 are made. so this means that to start with switches 0 and 1 will turn off output 0 then after switch 2 turns output 0 back on switches 0 and 1 seal it on after switch 2 is turned off, so switches 0 and 1 are serving opposite purposes from one step to another.

TW I dont know what else to do, this thing has drove me crazy, I dont how to explain what is wanted anybetter than this and like i mentioned earlier i found out there was another condition today which takes me right back to possiblly using a one shot, of coarse from what i can tell a one shot with allen bradley is a lot different than a shot with direct logic anyway Im not giving up altogether just giving up on trying to explain what i havent been able to make happen with my logic.

Sorry TW, I really appreciate yours and some others patience, maybe im not cut out for this, maybe i am maybe i'll be back someday.

Lancie I dont know how to make you believe that I have given you the whole set of specs as they were given to me. and I have found out somethings from the instructor that was not in the specs I just found out today that, where the reverse switch is and lights 1 and 2 are on y1 will be off and remain off until light 3 is turned on. when light 3 is turned on y1 will remain on even if light 3 is turned off as long as lights 1 and 2 are on. So that means where in the first step (lights 1 and 2 turned y1 off) at the end lights 1 and 2 will keep y1 on. I was so P****** when I left class today. I will not bother any of you any more until I can correctly give you the entire project spec'd out properly. And yeah i tried the same thing at PLC's.net, but I have'nt been chewed up and spit Out here.

Thanks a bunch TW, I'm going to class tommorrow with what i have but will definately try what you suggested about the latches again, i worked on it some but I have been staring at this thing so long i cant see straight no more. the wording in this puzzle has just drove me bonkers....lol

This is so crazy...lol ok i tried again with the latches also added rung comments but seems that this software only allows certain amount of text here is what I was trying to do again If switch 3 is off and switch 1 and 2 are on the output 0 will be on and remain on after either switch 1 or 2 is turned off, to turn output 0 off switch 2 must be turned on, if swithes 0, 1, and 2 are on then output 0 will be on. If switch 3 is on then output 1 will be on, if switches 3, 0, and 1 are on output 0 will turn off and remain off until switch 2 is turned on, output 0 will remain on after switch 2 is turned off as long as switches 0, and 1 are still on. I got it all but the last part where ouput 0 will remain on after switch 2 is turned off, thats the part that is stumping me right now. Hope this makes better sense

It is all one problem, or all of the same logic. I dont see an output 3. but both parts are to be in one program. I will rework this problem and solution and try to give a better description of what is wanted. the porblem I was given was so vague and wishy washy that even tho i think I understand what is wanted now, Im having a hard time I guess detailing it myself

What ouput 2 there is no Output 2.

criticism well taken I understand where you are coming from and apologize for the confusion. Thanks TW for your time and Criticism.

Ok guys here is the part of project one that i needed help with, and got chastized for not giving the complete program specs from another plc forum, however this step is the step i need the most hep with and should work according to spec regardless of what the other steps are. after I get this part working as sepcified i wll post the entire project and my solution to the problem at hand. .this Is my interpretation of the specs which seem to have been a big diasagreement, that i totally agree with because i had to get more specific info from the instructor before i could comprehend what was required here is exactly what the specs say. when the reverse switch is made and lights (lights mean switches according to the instructor...lol) 1 and 2 are on output 1 will be off and remain off until light 3 is made, output 1 will remain on after light 3 is turned off as long as lights 1 andd 2 are off. ( tought to read between the lines huh?) However after conversations with the instructor the quoted statement is what actually needs to happen and here is my solution. please critique and advise

Yeah done that but I do not have that option of member title, guess cause im a newbie

I havent been able to find anywhere or way to change My handle

ahhhhh i got it, thanks

Sorry I guess it isnt you huh....lol Thanks istolaruk

Sparky I realize no where in the spec does it say that light one was on with just inout 3 but after quizing the instructor that is what he wanted, go figure huh Question about your code? what is the output that you have labeled turn off, I mean is that just an internal bit used to tun off output 1? Thanks a bunch for your help

Thanks for the warm welcome TW. No having my homework done for kinda defeats the purpose of Me learning Programming, I want To learn, I did finish the first project and had the insructor test it today, had one mistake in the operation of it, but can you believe He didnt asked to look at the ladder logic. so anyway tnight of tommorow I'll post what I wrote and Let you guys Pick thru it and inform me of any Bad programming techniques or unnecessary steps. Thanks again

hello, I am a beginner at programming, went to another forum seeking help and was not fond of some of the responses I got. maybe I dont have thick enough skin, but I just dont find it amusing to be treated like an Idiot because I dont have the know how that a 30 yr veteran does. guess my question is, are there any programmers here that have the patience to help a rookie? Thanks in advance

Thanks gravitar, I have class tommorow we'll see how that goes, and I'll give you the latest help request. I am an Industrial electrician and by george if a guy comes along that wants to learn the trade, i'll do anything i can to help them, so thats in a nut shell what i am looking, some good tutoring without telling me how ignorant i am....lol and no it wasnt from Mr, Plc, Thanks again i'll be back tommorow with questions..............lol
