OPC is a common communication protocol in the industrial control field, used in devices such as PLCs, DCS, SCADA, and more. It enables interconnection and communication between industrial automation devices and can be integrated with other factory systems to enhance efficiency. Through the use of the物通博联 (Wu Tong Bolian) OPC intelligent gateway, MES (Manufacturing Execution System) can obtain real-time PLC data, enabling functions such as remote monitoring, remote control, and equipment management, thus assisting enterprises in creating a digital factory and information-based management.

The Modbus protocol is a universal language used in electronic controllers, facilitating communication between controllers, networking via Ethernet, and interaction with other devices. It has become a widely adopted industrial standard, enabling control devices from different manufacturers to connect into industrial networks for centralized monitoring.

LoRa modulation is a low-power, wide-area network communication technology, based on spread spectrum technology, developed by Semtech. LoRaWAN is a set of communication protocols and system architecture designed for long-range communication networks using LoRa technology. It functions as the Media Access Control (MAC) layer protocol.

The I2C bus, a well-known simple, bidirectional, two-wire synchronous serial bus technology developed by Philips, has been widely used to connect various sensors, LCD screens, and memory devices, among others. Previously, I2C was known for its combination of advantages from SPI and UART - it was lightweight, simple, and cost-effective. I2C facilitated fast and reliable data transfer between controllers and peripheral devices, supporting the interconnection of multiple devices for various data transmissions. However, as application requirements evolved, the long-standing limitations of I2C became evident, prompting an upgrade in serial bus technology.

Electrolytic capacitors play a crucial role in electronic devices. They are primarily used in DC power supply circuits, providing high-capacity, high-voltage capacitors to meet the demands of various application scenarios. In this article, we will delve into the role, application scenarios, and advantages of electrolytic capacitors.
