Hi all
i'm new her , i really want help with this question i totally don't understand it i think put nothing come in mind plz help because that question may come in my exam
the Question is :
Students are requested to write a programmable logic controller program using ladder diagram language to perform the required control algorithm (The required program should control PLC outputs based on PLC inputs)
1- Press the start Button ( should be hold for 5 seconds)
2- Start moving piston (A) from point (a) to point (b)
3- When piston (A) reaches point (b),start moving piston (B) from point (a) to point (b)
4- Move Piston (C) from (a) to (b) and then retract it back after 3 seconds
5- Move piston (A) back from point (b) to point (a) and move piston (B) from point (b) to point (a) in synchronized motions
6- Wait 10 seconds
7- Move piston (B) from point (a) to point (b)
8- Move piston (B) back from point (b) to point (a)1
9- Repeat the cycle again
- If the emergency button is pressed, the program should be stopped immediately
The start button should be pushed again to re-run the machine
