I'm new here. Reaching out for a very simple program (i think).
I am working on a conveyor system using some motor controllers with plc programming needed. ITOH DENKI is the brand name of these controllers. These guys have made their own software which I am not at all familiar with because I was barely even familiar with allen bradley.

I have attached a picture of our divert system on the conveyor with details about how it needs to be conditioned. I really need help fast to get this thing up and running. If someone would please get some ladder logic in my hands I would so very much appreciate it. My boss is on me about this thing. I'm beating around the bush with him to buy some time, but I can only stall for so long.

Thanks
 
A little extra info if you need it.

I have three sensors on a tower for height detection of boxes.
The two smallest boxes must divert to the left lane.
The large boxes must continue straight.
The divert (turntable) is controlled by 24v.
I also have a few motors in between that also work on sensors and must communicate so that I don't get jambs in the lanes.
 
response

it is their own version of a plc. In reality it is a motor controller with the capability to program with ladder logic. it's made by ITOH DENKI and it is the
IB-E01

The logic is written the same way but I am needing some help because I suck at ladder logic. I just haven't had the experience yet. But I need this job, so I can't choose to fail right now. I am working 2 jobs and going to school full time. I just can't get my thoughts wrapped around this project. Let me know if you have any creative ideas. Thanks.
 
Ok
step 1
write the sequence in step form
1 -
2 -

etc.
then we will guide you with ladder

Oops! Long pause here.....

1. It seems that your box height must be passed from the Tower Position (Sensors C and H) to Sensor E Position by using the R_IN_A flag relay. Probably at C & H sensors, you will want to use 2 more flags, for Tall and Medium, to be passed to Position Sensor E. When E sees a box, it checks for for R_IN_A and for Tall or Medium. IF R_IN_A is TRUE and MEDIUM is true, then Motor C is activated, and the Tall flag is passed to Motor B also. At the time that R_IN-A is true, it activates R_OUT_A, which signals the upstram tower zone that it is "busy". If TALL is true, then the box is passed to Sensor A and Motor A. At each zone, before a box is passed downstream, the downstream flag is checked to make sure that downstream is not busy and has room for another box.

2. Continue in the above fashion until the boxes have bee passed through all zones.

Maybe a job opportunity for me here, but all[/B of you gurus would have to be available 24/7 to not only answer but write/correct my code and and no slacking off as you have tried lately(pleasee $10/sec while sleeping Ian, you will certainly be paying the high earners Tax, as of from tonight/2015).
 
Hello rr46278, if you can provied me with an excel file where you put the Digital-Inputs/Digital-Outputs, Analog-Inputs/Analog-Outputs. And a functional description I will be able to help you out

Mate
If he could provide us any of that
We would help him too

We will not do it for him. He is employed to do this work.
If he can't do it, he is in the wrong job.

I have no problems with guiding solving and assisting.

BUT
Fair is fair. Do some work your self at least
 
I don't know what has happened in this case but I do know that some people put things in their CVs that aren't true and they also lie at interview. I've also seen situations arrise when HR try to recruit technicians and engineers without involvement from the engineering department.

At a company I used to work for, a software engineer was employed whose specialist subject was alleged to be serial comms. He was given a project to sort out the comms to set of microcontrollers but after one month was getting nowhere and "left". Sad but it happens.

Much the same here
But now we have fully trained automation specialists.
Still don't know how to turn on a light
 
I apologize for the delay. I have been doing 18 hour days between school and work. I am not completely ignorant in this matter. And I can figure this out on my own. But I figure if there are a bunch of people that can point me in the correct direction, than I can complete my task quicker and also learn more from many counselors. I am not expecting a handout from anyone. And I was not hired on to run PLC's. I work on egg grading machines that are pushing out 6 million eggs a day. But since I go to school for electronics, I was asked to complete this task. I have learned briefly how to use plc's in school so far. I even own a plc. but I do not have the expensive software to program it(allen bradley). I could hook this thing all up and make it run, but the next guy is gonna think "what the heck". So I would prefer to do it properly. Is there a problem with me reaching out to "professionals" for guidance? I appreciate all of the prompt replies. I will make my best effort to get back asap.

Here is the layout:

S1: sensor before height tower

S2: sensor after divert table (left or straight direction uses same sensor)

ST: sensor for tall box

SM: sensor for medium box

SS: sensor for short box

M1: motor before height tower

M2: motor after divert table left

M3: motor after divert table straight

D1: divert table (left or straight)


Here is the best way that I can describe the scenario:

If S2 = High;
then M1 = High

if S2 = Low for 5 seconds;
then M1 = High

If ST, SM, and SS = High
then D1 = Low

If ST = Low & SM, SS = High
then D1 = High

If ST, SM = Low & SS = High
Then D1 = High

If D1 = High
Then M2 = High for 5 seconds

If D1 = Low
Then M3 = High for 5 seconds
