Project description

1. How WIZnet products are used Internal board photos confirm the use of a CETUS JB1821C0D Ethernet module, which integrates the WIZnet W5500 chip. The W5500 handles the full TCP/IP stack in hardware, enabling efficient, reliable Ethernet communication with minimal load on the main MCU. This allows the DIG-M-2 to maintain a stable and secure cloud connection while ensuring precise real-time Modbus RTU communication over RS485. 2. Technologies, techniques, and unique implementation Modbus RTU over RS485: An industrial standard communication protocol; the gateway collects data from multiple…
