Core composition
Central Processing Unit (CPU): executes instructions and supports standardized programming languages such as Ladder Diagram and Structured Text.
Input/Output Components (I/O):
Digital I/O: Processing switch signals (such as buttons, sensors).
Analog I/O: Processing continuous variables such as temperature and pressure.
Special I/O: Supports high-speed counters, communication modules, etc.
Power module: Provides stable voltage (such as 24VDC/120VAC), with built-in lithium battery to maintain power-off data.
Programming unit: Program development and simulation are carried out through PC software such as PLCLogix and RSLogix.
application area
Petroleum industry: Control the valves, pumps, and sensors of drilling equipment, and use HMI to achieve real-time monitoring.
Glass and cement industry: precise control of raw material ratios and production processes, combined with distributed control systems (DCS) to enhance quality control.
Manufacturing industry: Automated production line control in industries such as automobiles, food, and textiles.
development history
Origin: In 1969, Modicon introduced the first PLC (model 084) to replace relay logic systems.
Evolution: From single control to support Ethernet communication, HMI interface, and modular design, following the IEC 61131-3 programming standard.
If the original system relies on XYCOM specific software, software compatibility needs to be evaluated when migrating to Pro Face, and some features may need to be redeveloped.
