Can u kindly please help me in the construction of ladder logic part if send u the flow chart. I have created a flow chart of my own.

Yes, I can. Your ladder should start something like the attached PDF files.

Where can i attach it, please?

When you create a post, click on the "Go Advanced" button and at the bottom of your screen you will see a button for "Attach Files".

I did the rungs. I am not so sure about it. I did study about latching the whole night, and sketched out something.

Vivi,

Using latching outputs (Set and Reset in the Siemens Microwin program) is a common beginner method. However, there are better ways.

Look at using the plain old Output. It will be safer for most of your logic rungs, and will work for all of them.

vivi,

Check the attachment

I laid a rough flow regarding ur project check whether i am right

Hello

Hello Sir,

Thank you so much for the advice you have given me. I have created the process flow and list out the I/O.

Can you please help me?

i need to submit my ladder logic programming this week. can you please help me.

Look at the attached and base your ladder logic on it - add anything else you think you may need into the "conditions" field, you require all the conditions to operate the output..........

Hello Mogie. yes i got it. Thank you so much.

can u help me to do 2 or three rungs first from my attached process flow.

i will try to do it and send to you for checking. can you please help me.

In the pdf I posted the "conditions" will be Inputs/Outputs/Markers etc in your ladder, the output will be the output controlling the indicators or valves.
All you have to do is "transform" it into the ladder.

Have a go from all the information that has been posted so far and then post your program here for comment.
Myself and others will help but only if you try yourself first,

Tip -
Start by assigning the input and output addresses

 

[viviathevan]

okay! i will get it done tommorrow and post it. please do correct me later on okay moggie. thank you so much.

viviathevan do you not feel that you are cheating by getting
people on the forum here to do the project for you? If you are finding it so difficult to do a simple college project how do you think you will be able to do it in the real world? As a former employer of graduates myself
who sold themselves to me with their CV, were very soon exposed as being incapable of the tasks set to them.
Needless to say, their careers with me were short.

I would urge you to put more effort into this yourself.

hello liam moran.

i am not seeking for full help btw. i am asking help to initiate me a few lines only. i will coupe up later on as i am very new to this programming. I have no guidance at all. I hope that without any teaching and guidance you cannot do anything.
Thank you.

vivi,

According to what i understood i created this flow,so u keep this as an idea & try to do ur program on ur own.

Read every comments that was written so that u can understand the positives & negatives while implementing ur project..

Hope it helps...

Hi Viviathevan,

One problem I see is that the project is fairly simple but you mentioned that the container only has a low and high sensor. How will you determine when it is half full ? You will need a level transmitter/float switch for that or manually check it. The rest is pretty straight forward. First compile your symbol table with comments, that way it will be easier to construct and understand if you are a beginner. Start simple, add a function per network eg: input switching a output on. As you progress you can add set & reset markers/timers etc. Microwin has all the icons in the toolbar for the standard bit logic. Try and get the software and maybe a simulator, it will give you the understanding behind what you program. I can give you a few pointers on how to get started if you are really lost.
