editCourse Objectives
- Primary Objectives- By the next class period students will be able to:
- Understand ladder logic and wiring motor for CW and CCW motion.
- Wiring a motor that opens a garage door up and down.
- Sub Objectives- The objectives will require that students be able to:
- Understand PLC structure
- Understand Ladder Logic
- Identify necessary components
- Wiring a motor that can rotate CW and CCW.
- Difficulties- Students may have difficulty:
- Understanding PLC architecture
- Writing a ladder logic
- Wiring a motor
- Real-World Contexts- There are many ways that students can use this material in the real-world, such as:
- Garage door opener
- Radar rotating control
- Solar cell aim to the Sun.

Legacy Cycle
editOBJECTIVE
By the next class period, students will be able to:
- Know how to program a PLC to change a DC motor rotation direction.
- Know wiring a relay and DC motor to PLC
The objectives will require that students be able to:
- Understand PLC structure
- Understand Ladder Logic
- Identify necessary components
- Wiring a motor that can rotate CW and CCW.
THE CHALLENGE
Rotate a solar cell angle to face the sun from morning to night.
Design a system that can face radar dome to an angle at an airplane that is approaching.
GENERATE IDEAS
Combine a direction control with time.
MULTIPLE PERSPECTIVES
Study control a motor with conditional statement
RESEARCH & REVISE
- Start ladder logic with turn on and off motor.
- Keep add more control so you can change rotation direction.
- Can you add automatic stop?
- Do you need emergency stop? If so can you add it?
TEST YOUR METTLE
- How many inputs and outputs were needed?
- Were you able to wire relay?
- What are the considerations for wiring?
- How can you buy parts?
- Google some suppliers who sell automation parts.
GO PUBLIC
- Make multimedia presentation and post to Web.
- Post completed program
- Show examples of application
Pre-Lesson Quiz
