Simple Protocol Conversion Mode; Multi-Host Mode - Ebyte NA111-A User Manual

Chengdu Ebyte Electronic Technology Co.,Ltd.
Enable(Check): Convert Modbus RTU protocol to Modbus TCP protocol.
Disabled: Do not perform protocol conversion but verify Modbus data, discard non-Modbus data (RTU/TCP)
and not transmit.

4.5.2 Simple Protocol Conversion Mode

Convert Modbus RTU data to Modbus TCP data, or convert Modbus TCP data to Modbus RTU data, to realize
the mutual conversion of Ethernet Modbus data and serial port Modbus data.
Simple protocol conversion can work in any mode (TCP client, TCP server, UDP client, UDP server etc.), no
matter what mode it is working in, there can only be one Modbus master station.
Simple protocol conversion configuration (TCP server mode as an example, the upper computer on the left,
web page on the right) :

4.5.3 Multi-host mode

There is only one Modbus master station for relatively simple protocol conversion, while the multi-master
mode can handle up to 6 Modbus TCP masters. One request is processed at a time, while the multi-host mode will
be sequenced according to the TCP request, and other links will wait) to solve the bus conflict problem (currently
only 6 host connections are supported), only supports working in TCP server mode, slave machine Only in the
serial port, otherwise it will not work properly.
It is recommended to configure "Simple Protocol Conversion" when no multi-channel host is used.
