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.
