i have a filling machine problem, the machine filling 3 bottles in same time it should have some elements in the work like in picture .... i have this problem from 2 weeks but nothing from my trying is succeed . im a new plc user i was using microcontroller pls can any one help me to solve this problem and how the ladder diagram can use the IF statement also how can i start with solving problems in plc coz i start to solve this problem with flowchart but .......not the same thing is there any basic flowchart for plc or away for solving problems in plc in the attach file x in\put y out\put and what is the diffirent between micro c and ladder Last edited by Rami00972; 31st October 2009 at 01:12 PM. | |

The best method is to first draw the flow chart. Then the ladder diagram. If that is too difficult, you can always also draw the addresses, containing logical gates before drawing ladder diagram. | |||

I don't understand your problem or your diagram. Maybe if you specify the available inputs, outputs and behaviour it may be easier to help you.

but I'm trying to make it a full automatic control I finished the mechanical system but still the control side in work..... X0 =C0 X1 = C1 x4,x5 limit SW X1 count 3 then Y1=1,Y0=0 then X0 count 3 then Y0=1 And Y4=1 ---> T0 : activate by X5 until 30 sec after that Y4=0 until X4=1-----> Y4=off another Q how can i make a 1. loop and an 2.initial condition like ta say y0=0 y1=1, y4=0 | ||

Sorry, your first image showed the whole process! I was using google chrome and it wasn't animated. I don't think you need a loop. As for initial conditions, you can set that using the first scan/cycle contact (which is #YSYS.SCAN1 for Kingfisher devices PC10/11; you'll likely find it in the manual) | |

I've attached a ladder logic diagram for the process as I understand it. I take it that Y4 stays on for as long as the filling is taking place? I didn't see a return coil for Y4.

Try reading the [programming] manual; I would think it would be in there.
