A:Core Components and Functions:
PLC(Programmable Logic Controller)
Function: Executes logic control, data processing, and equipment linkage commands.Features: Modular design with support for digital/analog input/output (I/O), suitable for complex industrial scenarios.
HMI (Human-Machine Interface)
Function: Provides a visual operation interface for real-time monitoring of equipment status, alarm messages, and parameter adjustments.
Features: Touchscreen interaction with multi-language support and customizable screens.
Sensors and Actuators:
Sensors (e.g., temperature, pressure, photoelectric): Collect on-site data and feed it back to the control system.
Actuators (e.g., motors, solenoid valves): Receive PLC commands to execute mechanical actions.
Communication Modules:
Supported protocols: Modbus, Profibus, Ethernet/IP, etc., enabling data exchange between PLCs, HMIs, and host computers.
Power Supply and Protection Devices
Uninterruptible Power Supply (UPS): Ensures safe system shutdown during power outages.
Circuit breakers and surge protectors: Prevent equipment damage from overloads and lightning strikes.
