Duration: 4 Days Classroom or 32 hours Online.
Audience: Process Control Engineers, PLC Engineers and Technicians, Instrument Engineers.
Prerequisites: Some control room exposure is desirable, but not required.
Course Material: Training slides, PLC Simulation Software and Industrial Examples.

Course Description:

This course provides a comprehensive practical foundation in Programmable Logic Controllers (PLCs), with a primary focus on Ladder Logic programming and control scheme design. It is designed to take students from basic hardware knowledge to proficiency in creating, debugging, and optimizing PLC programs for any vendor platform.

While understanding the system architecture is necessary—including how PLCs integrate with DCS and HMIs—the core of this training is logic design. Students will learn how to translate engineering requirements and P&IDs into functioning code using standard PLC instructions. The curriculum covers everything from digital/analog signal processing to complex sequence design, timers, counters, and math functions. Through hands-on simulation, participants will develop the skills to write robust ladder logic, troubleshoot existing programs, and implement safe, reliable control strategies in an industrial environment.

Learning Outcomes

At the end of this course, students will be able to:

  • Program with Confidence: Design, write, and troubleshoot Ladder Logic using relays, timers, counters, and boolean algorithms.
  • Translate P&IDs to Logic: Interpret P&IDs and SAMA diagrams and convert them into actual control schemes inside the PLC.
  • Master Control Strategies: Distinguish between and implement both sequence control (step-based) and continuous control loops.
  • Handle Industrial Signals: Configure I/O cards and implement algorithms for analog signal scaling and noise filtering.
  • Implement Advanced Functions: Use math blocks, comparison instructions, and data handling to solve complex process problems.
  • Integrate Systems: Understand how the PLC communicates with DCS networks and configure basic HMI elements for operator interaction.
