The communication mode uses the standard Modbus protocol. It uses a dual-line serial communication based on
RS485, and the physical interface adopts a conventional 3-pin 2.54 wiring terminal (A+, GND, B-) which is easy to
connect in series. The transmission mode is RTU, and the verification mode is CRC, with the CRC starting word being
FFFFH. The data mode is 8-bit asynchronous serial, with 1 stop bit and no parity bit. It supports multiple
communication speeds (see parameter table for details) Function parameter support 03H multi-register read, 06H
single register write.
