5.9.3 Multi-host mode

Relatively simple protocol conversion can only exist one Modbus master, while multi-master mode can handle
up to 4 Modbus TCP hosts, when multiple Modbus hosts access at the same time Modbus gateway will perform bus
occupancy scheduling (RS-485 bus can only handle one request at a time, while multi-master mode will sort and
process TCP requests according to the order of Other links will wait), thus solving the bus conflict problem
(currently only 4 hosts are supported), and only supports working in TCP server mode, slaves can only be on the
serial port, otherwise they cannot work properly.
As the number of hosts increases, the Modbus timeout time should be increased accordingly, and the request
interval should be increased. If multiple hosts need to request continuously at high speed, it is recommended to use
