routine  Modbus RTU  For half duplex Communication Protocol Only supports single master station docking with slave stations, industrial sites  PLC When multiple devices such as data acquisition instruments and monitoring systems simultaneously read the same instrument, bus conflicts and communication disorders are prone to occur. This two master and one slave module is designed for dual master shared slave scenarios, providing a one-stop solution to the pain points of concurrent access for multiple devices. http://weixin.qq.com/r/U0gPF_XEorjdraF09x1B (QR code automatic recognition) The module relies on multiple core mechanisms for stable operation: built-in data caching Proxy, pre stored slave register Data, dual master stations can read cache to avoid bus contention; collocation Logical Token Arbitration Accurately distinguish between two main station commands, return the response data to the original path, and prevent signal confusion. The device is compatible with two ...

  I. Project Background: Obstacles encountered in collecting data from special protocol electricity meters? Project Basic Information • Project Location: South Korea • Project Type: Factory Energy Consumption Data Collection This project is implemented by Shanghai Data Acquisition IoT Technology Co., Ltd. (official website: daq-iot.com). Core challenge: How to achieve efficient data collection from EDMI meters? Given the unique data acquisition requirements of the EDMI protocol meter (Mk6E), how can real-time data monitoring be achieved without disassembling the meter or modifying the wiring? Project implementation difficulties • Meter restrictions: Disassembling and rewiring the meter on site is prohibited. • Interface limitations: Only optical communication ports (infrared communication) are retained. • Unique protocol: Unconventional State Grid protocol, making parsing difficult. • Clear requirements: low cost, simple cabling, wireless transmission II. Technical Solution: Scheme...
