Introduction:
Mitsubishi PLC (Programmable Logic Controller) is a widely used industrial control device that plays a crucial role in automating and integrating various processes and machines. The upper controller of a Mitsubishi PLC system is responsible for coordinating and managing the overall operation of the system, ensuring that it runs efficiently and reliably. In this article, we will explore the wiring diagram of a Mitsubishi PLC upper controller, providing a detailed understanding of how the various components are interconnected to achieve the desired functionality.
Wiring Diagram Components:
1、Power Supply - The power supply unit provides the necessary electrical power to the PLC system. It ensures that the system operates within the specified voltage and current requirements.
2、Controller Main Unit - The controller main unit is the brain of the system, responsible for processing input signals, executing user programs, and generating output signals to control the process or machine.
3、Input Module - The input module receives input signals from various sensors or devices, such as limit switches, photoelectric sensors, and pressure sensors. It converts these signals into a format that can be processed by the controller main unit.
4、Output Module - The output module receives output signals from the controller main unit and converts them into a format that can be used to control actuators or devices, such as motors, relays, and solenoid valves.
5、Communication Module - The communication module allows the PLC system to communicate with other devices or systems, such as computers, touchscreens, and other PLC systems. It provides data acquisition, processing, and transmission capabilities.
6、Expansion Module - Expansion modules provide additional functionality to the PLC system, such as increased input/output points, specialized processing capabilities, or communication protocols. They are connected to the main unit via expansion cables or connectors.
