hi Licarry, don´t you think you should do your test by your self? I don´t think it makes sense to let your work do by others... Maybe it sounds hard for you, but I think if you need to do this by others, like every thread of you before, you should do something else. I don´t think this forum should be a platform for such requests. regards, |

Hello, Your question is very similar to the following old thread : 3s ON , 6s OFF timerTo do your task you need a timing diagram as I sketched .I think it is helpful while it is rough.You need a pulse signal from PLC internal pulse that can be parameterized in HW Config-->properties of CPU.Rung the counter with this pulse to count in up direction.Calculate in your diagram how many pule counting is enough to finalize the whole task and reset the counter that time.For each outputs, just use compares in series (or parallel) to activate them. I hope this helps, hdhosseini |

Dear Licarry, i don´t want to hurt you. I really like to help someone else. But I don´t think that it is a help for you, when someone else doing your homework or school test Almost everyone of us is earning money with programming, and we working hard. We are helping each other here in our free time. I ´m sorry to say you that the knowledge in plc-programming you to get your task done, probably is not enough to get it solved in a forum. I see that by the way you try to get your task solved. For example I give you one hint: Is your solution a ladder diagram? Sorry, I don´t want to be the bad guy for you. I just say what it seems to me, and what I think it is the truth. Maybe you are lucky, and there is one really nice guy, who is doing it for you. regards, |

Dear mopS04, No one do like that if i have a question means i tried it so only i got it and this is not any company or project work . I starting to learn PLC My self. As a beginner every one need guide so i treat all this forum members are my guide. As a student i ask my question to my known people and who is willing they will help me and also your way of answer is not good if you have problem in providing full solution means give some hint and ask me to try it myself and also last previous questions i got only hints from others not a solution i did solution my end your are also helped me to get solution in my previous question. On that time i said my heart thanks to you. But i don't know why you get this much of tension... please cool and if you have time help me to learn it. |

Hi Sequence requires 3 counters. it looks like mitsubishi (it uses addressing X,Y for inputs and outputs) project. counter C0 checks how many times we repeated the whole sequence counter C1 is sequence step counter counter C2 checks number of repeats for steps 1,2 copy counter to local variable allows us to compare counter against step number. if we can not use compare we can set counter C0 to 3 and count down until 0 the same with C2 and do sequencer using bit variables but this is less convenient. printout of siemens implementation (as FB) attached.

Your request is inconsistent: Please give solution for following problem in STL code ASAP. Please help me to complete it asap
1- Using the relay, timer, counter, pulse, and set/reset instructions in your handout, write a PLC ladder (...) and 'give solution ASAP' shall stipulate immediate shipment of a nice case of wine to one who 'gave solution ASAP' ;-) ;-) ;-) |
