The EU has enacted the Cyber Resilience Act (CRA), setting cybersecurity standards for digital products. Companies have 36 months to comply, with some reporting duties due in 21 months.

Who Must Follow the CRA?

All manufacturers, importers, and distributors selling digital products in the EU must comply. This includes consumer goods like smart devices, industrial equipment such as controllers, and software like operating systems.

Key Requirements for Manufacturers

• Secure Design: Build cybersecurity into products from the start, ensuring protection throughout their lifecycle.
• Vulnerability Fixes: Provide free updates to fix vulnerabilities unless agreed otherwise with customers.
• Documentation: Keep detailed records of vulnerabilities and components.
• Fast Reporting: Report vulnerabilities within 24 hours via ENISA’s platform.

Steps for Manufacturers

Pilz, an automation safety expert, advises manufacturers to act early. Work with suppliers and operators to define secure network zones and update processes. Proactive planning ensures compliance and boosts resilience.

Pilz supports manufacturers in meeting safety and cybersecurity standards. Without strong security, even advanced safety systems are at risk. Prevention is critical.

By adopting the CRA, manufacturers can ensure compliance, build customer trust, and stay competitive in a connected market. The CRA strengthens the EU’s digital ecosystem, and early action is key to success.

Bus Temperature Controller in Photovoltaic Laminating Machine

The “14th Five-Year Plan” in China emphasizes the advancement of energy revolution, aiming to build a clean, low-carbon, safe, and efficient energy system, while enhancing the energy supply security capacity. The plan accelerates the development of non-fossil energy sources, advocating both centralized and decentralized energy generation, and promotes the growth of clean energy bases, including wind power and photovoltaic (PV) power generation.

Photovoltaics have become the main force in the new energy system. Photovoltaic technology utilizes the photovoltaic effect at semiconductor interfaces to directly convert light energy into electrical energy. It primarily consists of three components: solar panels (modules), controllers, and inverters.

Process Flow of Solar Panel (Module) Manufacturing:

Laminating is a critical step in the production of solar panels. The pre-laid solar cells are placed in the laminating machine, where the air inside the components is evacuated through vacuum suction. The Siemens CPU host, using the Profinet-RT bus protocol, connects the AU7 697H-0RH22-PNT+SM633H-1RF22-P combination to read the thermistor values. The PID parameters then control the even heating of the laminating machine’s heating plate, causing the EVA (Ethylene-Vinyl Acetate) to melt and bond the solar cells, glass, and backsheet together. Finally, the AU7 697H-0RH22-PNT+SM633H-1RF22-P combination cools the components and removes the finished module.

The AU7 temperature control coupler is highly expandable, supporting up to seven modules. The coupler features 16 built-in PID control loops and can handle up to 40 temperature control channels. It includes 16 digital output channels and 16 thermistor/thermocouple input channels, integrating 40 intelligent fuzzy PID temperature control algorithms, powered by 24VDC.

Leading the Trend of Bus-based Intelligent Temperature Controllers

The AU7 series represents a breakthrough in traditional temperature control systems, offering programmable and highly intelligent capabilities. The high-speed bus and rapid temperature control capabilities position it at the forefront of a new era in industrial temperature management.

With its classic technology, the AU7 is reliable and stable, setting a new standard for modern temperature control solutions.

Brand new spot LAM Research

Selecting the right stepper motor requires precise calculations to ensure optimal performance. When making a selection, factors such as flange size, number of phases, motor length, shaft length, and the number of output wires must be carefully considered. Additionally, it’s essential to calculate torque and current requirements and verify compatibility with the matching driver.

1. Choosing the Torque for a Stepper Motor

The holding torque of a stepper motor is analogous to the “power” in traditional motors, though there are fundamental differences. The physical structure of stepper motors is distinct from that of AC or DC motors, as the output power of a stepper motor is variable. Selection is typically based on the required torque, i.e., the force needed to drive a load.

• For torque requirements below 0.6 N·m, motors with frame sizes of 28 mm, 35 mm, or 42 mm are suitable.
• For torque requirements above 0.6 N·m, 57 mm motors are generally more appropriate.
• For higher torque needs, such as several N·m or more, motors with frame sizes of 86 mm, 110 mm, or 130 mm are recommended.

Common Stepper Motor Sizes:
20 mm | 28 mm | 35 mm | 42 mm | 57 mm | 60 mm | 86 mm | 110 mm | 130 mm

2. Selecting the Number of Phases

The number of phases is an often-overlooked factor when selecting stepper motors. However, it significantly impacts performance. Different phase configurations (commonly two-phase, three-phase, or five-phase) provide varying levels of precision and stability.

• A higher number of phases results in smaller step angles and reduced vibration during operation.
• Two-phase motors are widely used in most applications.
• Three-phase motors are preferable for high-speed, high-torque applications.

3. Selecting the Motor Speed

The speed of a stepper motor requires careful consideration because the output torque is inversely proportional to the rotational speed.

• At low speeds (several hundred RPM or less), stepper motors produce higher output torque.
• At high speeds (1,000–9,000 RPM), the torque output decreases significantly.
• For applications requiring high-speed operation, motors with lower coil resistance and inductance are recommended.
• For low-speed, high-torque requirements, motors with higher inductance (e.g., 10–50 mH) and higher resistance are more suitable.

4. Selecting the No-Load Start Frequency

The no-load start frequency, commonly referred to as the “start frequency,” is a critical parameter for stepper motors.

• Applications that require frequent instantaneous starts and stops, especially at speeds around 1,000 RPM or higher, often require an “accelerated start.”
• For direct high-speed starts, reactive or permanent magnet stepper motors with higher start frequencies are ideal.

By carefully analyzing these factors, you can select a stepper motor that meets your specific application requirements while ensuring reliable and efficient operation.
