Siemens Programmable Logic Controllers (PLC’s) – Maintenance and Troubleshooting

Code: Technical

Duration: 5 Days

Location: Doha

Fee: QAR 12,900

Course Overview

This course has been developed to give participants an understanding of programmable Logic Controllers (PLC’s) systems basic programming concept and their applications in Industrial Automation Systems (IAS) extensively within the Oil & Gas, Petrochemical, Power Generation, Water/Waste Water Treatments, Pharmaceutical, Food and beverage, Transportation, Pulp and Paper and other Process Industries.The course will cover in details fundamental principles, architectures and definitions of the PLC’s and their connectivity with different known electric and automation control system components. In additional, a detailed discussion of PLC’s hardware structure components, I/O modules, intelligent modules, communication protocols, installation, maintenance & Troubleshooting.The course also includes basics of PLC’s programming concepts for PLC programmers, maintenance and troubleshooting engineers/technicians.

Course Objectives

On completion of this course, the trainee will be able to evaluate the suitability and application of current in-house PLC systems and offer guidance and advise on whether such systems may be modified or improved, consequently he will be able to leverage his skills to potentially cause an increase within the plant or process in terms of overall productivity and efficiency through analysis of current systems, also the trainee will be better equipped to advise on new system communication installations in terms of evaluating choices between different industrial automation systems.
