Programmable Logic Controllers (PLC) and SCADA Systems

This Course introduces you to Programmable Controllers, its general control Concept and the areas of applications in industry in which they are being applied. General operation, including its scanning method, is also covered in an introductory manner to immediately get you into the relationship of electromechanical relay control systems and programmable controller based systems. Input and output addressing of field devices is also covered as it relates to programmable controllers and its interaction with the real world.
