otherwise it may be due to the serial port transmission rate being much lower than the Ethernet
transmission rate causing packet loss. If quick response is needed, it is recommended to use a
"storage gateway"). It only supports working in TCP server mode, and the slave can only work on
the serial port, Otherwise, it will not work properly.
As the number of hosts increases, the Modbus timeout should be increased accordingly. If
multiple hosts need to continuously request high-speed requests, it is recommended to use a "storage
gateway". It is recommended to configure it as "simple protocol conversion" when there are no
multiple hosts used.
Refer to "Simple Protocol Conversion" for software configuration and register configuration,
and enable multiple Modbus Poll software simultaneously (for example, 3-channel model can
support up to 9 channels).
5.4.4 Storage gateway
A storage gateway not only arbitrates bus data but also stores duplicate read instructions. When
different hosts request the same data, the gateway does not need to inquire about the register status of
the RTU device multiple times, but directly returns the cached data in the storage area, greatly
improving the multi host request processing ability of the gateway and shortening the time consumed
in the entire request process. Users can customize the storage area instruction polling interval and
instruction storage time according to their needs.
