Hi
In this we going to see how to write a simple LADDER LOGIC program to switch on a motor with one start input & off the motor through a stop input.
PLC INPUT
1. START - X0 [ PUSH BUTTON ]
2. STOP - X1 [ PUSH BUTTON ]
OUTPUT
1. MOTOR - Y0 .
STATUS 1
X0- OFF
X1 - OFF
Through this example you understand about how to switch on and off a object / motor / lamp ..etc. And through this example we came to know what is holding in ladder logic.

X1 - OFF
STATUS 2
X0 - ON
X1 - OFF
STATUS 3
X0 - OFF
X1 - OFF
Y0 - ON
In this above image the output register will be in on after its input is off through holding it in relay.
STATUS 4
X0 - OFF
X1 - ON
Y0 - OFF
