Project description
1. Introduction Modbus RTU Based on serial communication (such as RS-485), it uses a master-slave query-response mode. Data is transmitted in binary format, with each byte containing 1 start bit, 8 data bits, 1 parity bit (optional), and 1 stop bit. There is no fixed frame header/tail; frame boundaries are distinguished by time intervals (typically 3.5 character times). Its advantages are low hardware cost and strong anti-interference capabilities, making it suitable for short-distance, low-speed scenarios (such as sensor networks), but strict timing control is required when there are…
