Some real-life scenarios where PLCs are commonly used is given below.  1. Identify and list the input and output for each of the scenario 2. Draw the ladder logic diagram equivalent to each of the scenarios. Scenario 3: A pushbutton will STARTthe conveyor belt. Make sure that the conveyor belt  can be stopped at any time with an E-STOP. While the package is moving  through the conveyor, the green light will be ON.  Once the package reaches the limit switch location, we are ready to fill the  package. Note that the limit switch is usually in Normally Closed condition  and it opens the contact when the package reaches the sensor contact. The conveyor motor will STOP at this condition, the green light will turn off and  the RED light will be ON

Scenario 3:
A pushbutton will STARTthe conveyor belt. Make sure that the conveyor belt 
can be stopped at any time with an E-STOP. While the package is moving 
through the conveyor, the green light will be ON. 
Once the package reaches the limit switch location, we are ready to fill the 
package. Note that the limit switch is usually in Normally Closed condition 
and it opens the contact when the package reaches the sensor contact. The
conveyor motor will STOP at this condition, the green light will turn off and
