Design a PLC ladder logic program to implement an automatic
Car-Wash process. The system should have a
start and stop pushbuttons. When a Car enters the washing skid, a
load cell switch is activated and the
following sequence is performed automatically:
1. Soaping for (20) sec through soap nozzles
2. Washing for (120) sec using big brushes
3. Rinsing for (60) sec using water nozzles
4. Drying for (40) sec using air nozzles
After finishing this process, the washing skid is moved out through
a conveyor belt (motor) until a stop limit
switch is activated.
