PLC의 H/W 결선도 작성법

• PLC에 입력 및 출력 장치를 접속한 H/W 도면
• 교류 전원은 차단기(NFB)와 노이즈 필터를 통해 PLC에 인가
• PLC 입력 및 출력 모듈에 접속된 장치는 외부전원(SMPS)으로 구동

What Is a Conceptual Diagram?

• A conceptual diagram is a visual representation of the ways in which abstract concepts are related. It is used as an aid in visualizing processes or systems at a high level through a series of unique lines and shapes. Conceptual diagrams are widely employed in fields as diverse as business, science, and manufacturing, and they may be created in a variety of ways to suit the project’s needs.
• from the latin word 'conceptus' meaning thought & the greek word 'diagramma' meaning drawing
• depict essential attributes of the system
• evolve to capture an increasing understanding of the system
