4 Modules
The complete course consists of 4 video modules and 2 PDF manuals which include self-assessment
Module 1 – Fundamentals of Automatic Control
At the end of this module learners will be able to:
• Identify the 3 basic stages of a typical automatic control system
• Describe the operation of a two state switch and a two state logic
• Explain the operation of a two state relay, and describe the function as a control device
• Explain the basic differences between a relay logic controller and a programmable logic controller
Module 2 – Relay Logic Devices & Ladder Diagrams At the end of this module learners will be able to:
• Identify typical symbols in relay ladder logic diagrams
• Identify typical input, logic and output devices
• Describe typical circuit operation from a ladder logic
Module 3 – PLC Hardware & Ladder Logic
At the end of this module learners will be able to:
• Describe the purpose and function of I/O’s
• Decipher address locations and devices involved in PLC ladder logic diagrams
• Describe how a CPU processes input signals to control the state of outputs
• Explain the basic differences between a relay logic controller and a programmable controller
Module 4 – The PLC as an Information Processor
At the end of this module learners will be able to:
• Describe how the PLC processes information by a process called SCAN
• Describe the basic operation of the CPU and its memory circuits
• Describe the internal logic devices that exist in the virtual world of the PLC
• Explain the operation of contacts, coils, timers and counters that appear in a typical PLC ladder logic diagram
