Choosing Between PLC or Embedded Systems for EEE Students in the Indo Automation Era

The field of industrial electrical and electronics engineering (EEE) has never been more dynamic and diverse. Among the plethora of options, Programmable Logic Controllers (PLC) and embedded systems stand out as pivotal technologies shaping the future of industrial automation. Both fields present significant opportunities, but the choice between them ultimately depends on your specific interests and career goals.

PLC: The Backbone of Industrial Automation

Programmable Logic Controllers are at the heart of many industrial processes. The PLC market is vast and growing, with significant opportunities for automation in sectors ranging from manufacturing to energy. India, in particular, is witnessing a surge in PLC applications due to the increasing demand for automation products and solutions. Major multinational companies (MNCs) and core automation players are operating in India, providing ample opportunities for PLC engineers.

A PLC programmer is more than just a technician; they require a diverse set of skills, including:

PLC Programming: Writing and debugging control programs. HMI/MMI Graphic Development: Creating intuitive user interfaces. VFD Installation and Commissioning: Handling variable frequency drives for motor control. Servo System Configuration: Setting up precise motion control systems. Industrial Networking: Implementing communication protocols. Control System Design Service: Designing and implementing control systems. Panel Design and Layout: Creating and arranging control panels. Process Instrumentation PIDs: Managing control loops. Control System Architecture: Planning the overall system structure. Control Strategy Logic: Developing control algorithms. System Wiring Schematics: Crafting detailed wiring diagrams. Communications and Networks: Ensuring seamless communication. Field Wiring Diagrams: Accurate field wiring diagrams. PLC I/O Schematics: Wiring PLC input and output. Termination I/O Schedules: Managing termination schedules. Barcode and RFID Application: Implementing barcode and RFID systems. SCADA Development as per Requirement: Developing supervisory control and data acquisition systems.

Embedded Systems: The Seed of Innovation

Embedded systems represent a broader realm of technology where custom-built microcontrollers and software interact with hardware to perform specific tasks. As part of the "Make in India" initiative, there is a burgeoning demand for both hardware and software engineers skilled in embedded systems. This domain offers a wide range of applications, from industrial automation to process control systems.

Embedded systems professionals often work on:

Custom Hardware Development: Building custom components and systems. Low-Level Programming: Working with assembly language and microprogramming. System Integration: Combining hardware and software to create functional systems. Field Deployment: Implementing systems in real-world industrial settings. Research and Development: Innovating new technologies.

Key areas of focus in embedded systems include:

Microcontroller Architecture: Understanding and optimizing microcontroller design. Real-Time Systems: Developing systems that respond to real-time events. IoT Applications: Implementing Internet of Things (IoT) solutions. Automotive Electronics: Designing and deploying systems in vehicles. Medical Devices: Developing specialized medical equipment.

Comparing PLC and Embedded Systems

While both PLC and embedded systems are crucial in the field of industrial automation, they serve different purposes and require distinct skill sets:

Digital Logic: Both domains rely on digital logic in their core functions. Component-Level Building: Embedded systems involve building and programming at the component level, focused on assembly language and microprogramming. Field Utilization: PLC utilizes a user program for field use, making it practical and directly applicable in industrial settings. Imps on Industry: PLC professionals work closely with industries, often interfacing with field systems, while embedded professionals may work in factories or labs.

Conclusion

For EEE students, the choice between PLC and embedded systems depends on your specific interests and career goals. PLC programming offers a robust and practical approach to industrial automation, while embedded systems provide a deep dive into custom hardware and software integration. Both fields present excellent job opportunities, and as the demand for automation technology continues to grow, the future looks promising.

Key Takeaways:

PLC is ideal for those interested in practical, field-oriented work in industrial settings. Embedded systems are suited for those who enjoy building custom hardware and working at the component level. Broadening your skill set in either field can lead to more diverse career opportunities.
