Course objective

Provide the attendee with an introduction to ladder logic independent of any specific PLC on the market. Showing how to read and understand ladder logic diagrams and schematics.

Who will benefit from this course

• Technicians and advanced assemblers who have to deal with subsystems incorporating PLCs.
• Field service technicians having to troubleshoot equipment controlled by PLCs.
• Engineers & Technical managers who have only been taught programming without ever encountering ladder logic.
• Account managers needing to sell programmable automation components & equipment.

Course syllabus

• What is a circuit.
• The different kinds of switches.
• What is a rotary cam switch.
• Rotary cam switch circuits.

What is Unique About This Course

• Carefully covers the fundamentals of relays so that any further learning on PLCs will be much less confusing.
• Provides more than just one example of each topic.
• Uses real world applications for examples.
• Takes the time to allow full mastery of topics before rushing on to the next subject.
• Explains the WHY along with the WHAT and HOW.
• Covers what existing technologies are likely to be encountered in the real industrial environment. This is very useful for maintenance, servicing, or in properly understanding what one is trying to replace with newer technology.
