4.1.2. Host mode
In host mode (register value is 0x00), the data sent by the network or 485 bus (transmitter) to the device satisfies the
Modbus RTU, Modbus TCP protocol, and the address in the data is the device address, and the device responds to the
sender with the same protocol. If the data sent by the network or 485 bus to the device does not satisfy the Modbus RTU,
Modbus TCP protocol, or satisfy the Modbus RTU, Modbus TCP protocol but the data address is not the device address,
the data from the 485 bus will be transmitted to the network, and the data from the network will be transmitted to the 485
bus.
This function of host mode can realize the cascade function of devices and the data transmission between 485 bus and
network.
