Skill Area 1 - Programmable Logic Controller

What are the prerequisite Skills and Knowledge that an Engineer need to understand the Control Circuit using Ladder Diagrams?

• An Engineer must Know Electrical Devices, The Schematic Symbols and Understand the Structure of a Ladder Diagram and the Component Designations in the Ladder Diagram.

• An Engineer must know how to Program.

• An Engineer must know how to play Mobile Legend

• An Engineer no need Skills and Knowledge.

Which of the following are the Technique for Interpreting Ladder Diagram?

• Find out what the Control Circuit is supposed to do and then determine how it do the action or function of the circuit. This may simplify the attempts to understand Control Circuit functionality from a ladder diagram

• Learned about the Control Circuit before attempting to interpret the functionality of the control circuit by Talking to someone who is familiar with the controlled equipment, reading equipment operating descriptions and consulting manufacturer on the equipment

• Once you know the control functions of the circuit, you may then be ready to consult the ladder diagram

• All of the Above.
