Multihost Mode - Ebyte E180-DTU(Z20-ETH) User Manual

3.7.2 Multihost mode

Multiple host mode can handle up to 6 Modbus TCP hosts. When multiple Modbus hosts are accessed at the same time, the
Modbus gateway will occupy bus scheduling (RS-485 bus can only process one request at a time, while multiple host mode will
sort according to TCP request, and other links wait), so as to solve the problem of bus clashes (currently only support 6 host
connections), only supports working in TCP server mode, slave only in the serial port, otherwise it cannot work normally.
It is recommended to configure Simple Protocol Conversion when there is no multiple host in use.
