4.6.2 Multi-host mode
Multi-host mode can handle up to 5 Modbus TCP hosts. When multiple Modbus hosts visit at
the same time, Modbus gateway will carry out bus occupancy scheduling (RS-485 bus can only
handle one request at a time, while multi-host mode will sort according to TCP requests, and other
links will wait), thus solving the bus conflict problem (currently only supports 6-host connection),
only supports working in TCP server mode, and slaves can only work in serial port, otherwise it
cannot work normally.
It is recommended to configure "simple protocol conversion" when no multiplex hosts are used.
