2. Interface various hardware components with Programmable Logic Controllers(PLC)

3. Develop ladder program for simple applications

4. Appreciate the use HMI, SCADA, DCS, RTUs and other latest technologies in Industrial Automation

Learning Resources

1. 1. Study the following appliances/ automation systems and identify various elements used and their function 

      • Air conditioning System 

      • Automatic water level control 

      • Elevator (for Three Floor) 

      • Washing Machine 

Write the Block Diagram For each and explain with a Multimedia Presentation

1. 2. Demonstrate the working of below shown Switches/Sensor. 

      • Various industrial Switches (Push Button, ON/OFF, Toggle, Emergency, Rotary Switches etc.) 

      • Proximity- Inductive, Capacitive and Optical Sensor 

      • Temperature Sensor d Float Sensors

   3. Demonstrate the Forward and Reversal of 

      • Stepper Motors with the help of Drivers

      • DC Motors with the help of Drivers

   4. Execute energized motor or bulb using Switches in series (AND Logic) or Parallel (OR Logic)

   5. Write ladder diagram to test digital logic gates(AND/OR/NOT/NAND/NOR/EXOR) and Execute/Simulate the same

   6. There are 3 mixing devices on a processing line A,B,C. After the process begin mixer-A is to start after 7 seconds elapse, next mixer-B is to start 3.6 second after A. Mixer-C is to start 5 seconds after B. All of then remain ON until a master enable switch is turned off. Develop PLC ladder diagram, timing diagram and simulate the same 

   7. Write a Ladder Program to count the number of Items moving on a conveyor Belt and Execute/Simulate the same

   8. Execute the Ladder Program for relay based motor control automation such that the motor reverses its direction when the limit switches are activated and also Demonstrate by interfacing with PLC 

   9. Simulate the PLC ladder diagram developed for an alarm system and also Demonstrate by interfacing with PLC

   10. Implement controlling of Traffic Lights in PLC using Ladder Diagram programming language 

   11. PLC Program to Control Level of a Single Tank

Problem Description: One open tank is installed in the plant of which liquid level is to be controlled. When level reaches the Level Low, Outlet flow is blocked and inlet flow is allowed until high level is achieved. And when Level High is detected, outlet flow is allowed and inlet flow is blocked.

1. 12. Execute automatic door system using optical sensor and linear actuator

   13. Design ladder diagram for an Automatic Elevator control Also, Test and simulate the ladder diagram designed to operate and control the Automatic Elevator control or Test and simulate a ladder diagram designed to operate and control the Lift

   14. Simulate a ladder diagram for car parking. 

   15. Multi media Exposure to SCADA system OR Make case study visiting any nearby industry (Packaging/Milk Dairy/Processing) using HMI, SCADA/DCS systems

   16. Demonstrate the HMI interface to control Light in AND/OR Logic

1.   Write a PLC Ladder Program to Switching on/off the Lamp whether they are at the bottom or the top of the staircase.

2.   The production line may be powered off accidentally or turned off for noon break. The program is to control the counter to retain the counted number and resume counting after the power is turned ON again. When the daily production reaches 500, the target completed indicator will be ON to remind the operator for keeping a record. Press the Clear button to clear the history records. The counter will start counting from 0 again. Write a PLC Ladder Program to perform this operation

3.   Write a PLC Ladder Program Providing lubricant for the gear box before the lathe spindle starts to run which aims to ensure that the oil pump motor starts first and the main motor starts subsequently

4.   Write a PLC Ladder Program such that once the photoelectric sensor detects 10 products, the robotic arm will begin to pack up. When the action is completed, the robotic arm and the counter will be reset.

5.   Develop PLC Programming Examples on Industrial Automation according to the logic given below,

o   A Saw, Fan and oil pump all go ON when a start button is pressed.

o   If the saw has operated less than 20s, the oil pump should go off when the saw is turned off and the fan is to run for an additional 5s after the shutdown of the saw.

o   If the saw has operated for more than 20s, the fan should remain on until reset by a separate fan reset button and the oil pump should remain on for an additional 10 s after the saw is turned off

6.   Develop and Simulate a PLC Ladder Diagram for Bottle Filling Plant

7.   Study and present a Report on home Automation

8.   Study and present a Report on Embedded systems in Automation

9.   Study and present a Report on Automation in Processing Industries
