Summary:

Use IP3416 to design a ladder diagram to control a motor. The sequence of operation is described as follows: The motor is stopped at the beginning of the process A normally opened (NO) switch is used to start the whole process. An alarm will be triggered and last for 5 seconds when the start

button is pushed. A warning light will be turned on when the start button is pushed. The motor will start running 5 seconds after the start button is

pushed. (Use a normally open momentary switch) The motor will stop immediately and the light will be turned off if

a stop button is pushed. (Use a normally close momentary switch) The motor will stop and the light will be turned off automatically

after 30 seconds of running.

Connections:

Plc is given an 110V supply from the mains. It is connected to the laptop via USB to RS232 cable using EPS software.

In the circuit 5V supply is provided to the switching circuit. In switching circuit, we have used to switches. One for turning on the whole process and the second one for terminating the process at any instance. Alarm, LED and Motor is connected on the output side of IP3614.

Circuit Diagram:

Ladder Diagram:

Fig 2: Ladder Diagram

Procedure:

1. Initially the momentary switch is turned on, which charges the coil R0.

2. R0 will turn on alarm and light. Later the timer T13 and T14 will be initialized.

3. After 5sec motor will be turned on and alarm will be turned off.4. Timer T15 will be initialized for the motor. 5. And after 30sec the light and motor will be turned off

automatically.

Conclusions:

Thus on pushing turn on switch the light and alarm is turned. After 5sec the alarm will turn off and motor starts automatically. After 30sec the light and motor turns off automatically.
