Hi..i`ve got some problem with ladder diagram creating..here is the question..this is for my assignment task..
"When the START pushbutton(0000) is pressed,the conveyer belt(1000) will start moving.When the sensor S1(0002) have detected 50 products,conveyer belt will stop and alarm(1001) will sound.The alarm will sound for 1 minute,after a minute conveyer belt will move again.When STOP push button is pressed the operation will stop."
Thats the question.Hope anyone out there could help me with the ladder diagram ...tq

That isn't a question.
That is a request for someone else to do your assignment.
Good luck with that.

You need to post what you've done so far if you want to get any help. ;-)
