Figure 2 (see below) shows an example of a ladder diagram for a circuit that is used to start and stop a motor using push buttons. In the normal state, push button 1 is open and push button 2 closed. Figure 2 – Figure 2 – Stop-start switch. When button 1 is pressed, the motor circuit is completed and the motor starts.

Sensor X2 (I0.3) sense down position of the Bottle & Sensor X1 (I0.2) Sense top position of the bottle. In PLC, we designed the circuit which follows command that if sensor X2 (I0.3) sense the bottle & sensor X1 (I0.2) does not sense the bottle then the pneumatic actuator (Q0.2) will come in action & it will reject the bottle from the conveyor.

If the XIC is False, the PLC aborts this rung. Step 3 - The hypothetical current goes to the next instruction. Repeats Step 2 until the rung is completed. Step 4 - The PLC moves to the rung below. Ladder Logic PLC Programming XIC = OFF Example. In the example above, the XIC Instruction is tied to the bit "Condition1".

When part is placed on conveyor at position 1, and when cycle start button is pressed it moves to position 2. After reaching at position 2 it will stop for stamping process. After stamping process part will go at position 3 and from here it will be taken away from conveyor manually. Write PLC program for this process using ladder diagram language.

Draw a PLC Ladder logic diagram for a conveyor system. The system feeds a boxed product into a palletizing system. The palletizing system can only handle 20 boxes per minute. The conveyor motor is connected to a variable frequency drive (VFD) which is capable of running at 3 different speeds by sending a set of signals on two wires.
