RS485 TO ETH ( B)
7 . 3 . DISABLE STORAGE FUNCTIONS
Although the storage Modbus has a faster response speed, some users do not want the RTU
device to receive a large number of query commands, which affects the internal processing
speed of the instrument. The storage function can be turned off at this time.
The method to disable the storage type is to click the "More Advanced Settings" button in
the "Parameter Configuration" dialog box, remove one support and one enable as shown in
Figure 27 and click OK. Then go back to the device settings and click Modify settings.
Note that when using the Web method to configure the conversion protocol, the default is a
non- storage Modbus gateway.

7 . 4 . MULTI - HOST FUNCTION
As shown in Figure 27, "Enable RS485 Multi- Host" and "Enable RS485 bus conflict detection"
are multi-host functions. They are generally enabled and disabled at the same time. After
enabling, let the device whose conversion protocol is Modbus TCP has the storage Modbus
gateway function, otherwise it is a non-storage Modbus gateway; if the conversion protocol is
None, generally the user-defined RS485 protocol can also have serial devices accessed by
multiple hosts at the same time This function cannot be achieved in a pure RS485 network,
because multiple master stations sending at the same time will cause conflicts on the RS485 bus.
The multiple hosts of this serial server can "coordinate" the RS485 bus to achieve the purpose of
multi-host access.
