In industrial automation, Mitsubishi MELSEC-F series PLCs serve as the core control unit for small and medium-sized automated machinery, packaging lines, and processing equipment. Among the most popular 48-point transistor-output models on the market, the FX3U-48MT (legacy end-of-life PLC) and FX5U-48MT (modern iQ-F upgraded successor) dominate mainstream on-site applications. For automation and maintenance technicians, the […]

Introduction As smart manufacturing and Industry 4.0 continue to evolve, modern industrial automation systems are raising unprecedented demands for low-latency communication, stable real-time data transmission, and seamless multi-device network interconnection. Traditional industrial Ethernet modules often face bottlenecks such as limited motion control axes, insufficient connection capacity, and cumbersome network topology deployment, especially in high-precision production

Siemens 6ES5420-4UA14 SIMATIC S5 Digital Input Module Strengthens Industrial Legacy Automation Systems In many long-life industrial plants, legacy automation systems are still operating reliably despite their age. Among them, the Siemens 6ES5420-4UA14 SIMATIC S5 420-4 Digital Input Module continues to play an important role in maintaining stable signal acquisition and system continuity. As factories focus

Like other fanuc servo motors, DC motors generate heat during operation, which will accumulate on the coil and cause the coil temperature to rise. The heat will also be transmitted to the metal shell of the motor, and the fan can discharge the heat of the motor shell in time, so as to dissipate the

1. Rack or Chassis: Backbone of GE PLC Modular Architecture The rack or chassis serves as the fundamental backbone for any programmable logic controller (PLC) system. It physically houses and connects all the essential PLC hardware components, including the CPU, power supply modules, signal modules, and communication processors. More than just a frame, the rack

Emergency On-Site Troubleshooting: HMI Touch Screen Freezing / “PLC Unresponsive”? Electrical Technician’s 3-Minute Rapid Troubleshooting SOP When your HMI touch screen suddenly becomes unresponsive or your PLC reports “no response,” quick action is crucial to minimize downtime and prevent potential damage. This 3-minute SOP guides electrical technicians through an efficient, systematic troubleshooting process designed to

No More Wrong Parts Replacement! Understanding the Real Difference Between Servo System “Overcurrent” and “Overload” Alarms with a 5-Step Cross-Check Method When dealing with servo systems, false alarms often lead to unnecessary part replacements, increasing downtime and costs. The key to avoiding this cycle is understanding the true difference between “overcurrent” and “overload” alarms. Misdiagnosing these issues

Preliminary fault localization (rapidly pinpointing the fault scope) 1.Observe the status of the PLC indicator lights: focus on checking the power light (POWER), running light (RUN), and fault light (ERROR/Fault). If the power light is not on, prioritize troubleshooting the power supply line (voltage, loose wiring); if the running light is off/flashing, it is highly

Power system: intelligent control of the entire process of power generation, distribution, and utilization Power plant control: automatic regulation of boiler, turbine, generator, and auxiliary systems to ensure stable power generation. Substation/Distribution Room: The high-voltage cabinet, low-voltage cabinet, circuit breaker, and protection device are controlled in a coordinated manner to achieve automatic switching, fault alarming,

Servo drive is a kind of controller used to control servo motor. Its function is similar to that of frequency converter acting on ordinary AC motor. It is a part of servo system and is mainly used in high-precision positioning system. Generally, the servo motor is controlled by three methods of position, speed and torque
