router, it will be this static IP.
DNS address The resolution address generally does not need to be changed
Basic information area------modbus parameter area (the configuration will take effect after restarting)
Modbus working mode The five types of simple protocol conversion/multi-host/storage type/configuration
type/active upload type can be set respectively. The default is disabled, that is, the modbus functional area is not
enabled. Change the option to any type, which is enabled. Note: enable After that, the modbus gateway will work
on link one, only support TCP interaction, and will actively close the other three links, please do not use the other
three links. The following briefly introduces several gateway modes:
Simple protocol conversion: the most commonly used, simple TCP-RTU conversion
Multi-host mode: that is, for example, both hosts A/B will access device information through modbus. If A/B
initiates an access request at the same time, for example, A has accessed, modbus will enter the busy state, and the
access information of B will be stored. Down, wait for the end of the interaction of host A, and then execute the
interaction of host B, thus avoiding the information conflict of multiple host modbus buses
Storage gateway: Since the interaction speed of the 485 interactive terminal is slower than that of the network
terminal, many bus waits originate from the slow side, and a storage gateway, such as the host accesses an
instruction, then the device as a modbus gateway will "remember" "This command, and keep polling, and save the
polling result in the device, then next time the host accesses this data again, the device as a modbus gateway will
not go to 485 to send the inquiry information, wait for the content to return, and then return the content. Instead, it
directly returns the polling content stored in the device to the host, making the interaction speed smoother.
Configuration gateway: Similar to storage gateway, but you can configure common query commands into the
device in advance, which means that the device does not need to be issued by the host, and directly remembers
these commands. The subsequent workflow is the same as the storage gateway.
Active upload: You can configure the command in the modbus command configuration (this command
configuration area is the configuration used by the configuration gateway and the active upload uniformly). After
the configuration, just like the configuration gateway, the device as a modbus gateway will send a query through
485 information, but after the query result is obtained here, it will be directly returned to the host through the
network.

：
It is supported to not check this item when selecting multiple hosts, and check it at other times.
This is a common usage, which means that the default network terminal runs TCP type data, and then the device
acts as a modbus gateway to the RTU data run by the slave terminal.
