Note: If the addressing parameters in Ethernet network (MAC-address, IP- address, DHCP settings) are
modified and saved, the browser may not load the pa
ge after the restart of the unit by pressing the “Restart” button.
This can happen as the browser continues to reply over the previous address. In this case, the connection should be
made anew.
Clicking the “Exit” button the will close the setup mode and
a password request appears once again.
7.4 Configuring
ЕТ-485 through Modbus interface
Setting via Modbus-interface shall be provided if the unit is connected over the Modbus client, which is supporting the
Modbus TCP protocol. The connection is established using its IP-address (factory setting - 192.168.0.111) with the indication
of Modbus-identifier (factory setting - 111).
Write the password string into the password input register (see Table 5) before setting parameters. Factory set
password – is 11111, i.e. write 49 (ASCII-code for one) to record the factory set password to registers 0 - 4. If the password is
correct, the mode register (see Table 6) takes the value of 1 – setup mode.
The instruction register (see Table 5), as well as registers for the collection of Modbus customizable parameters (see
Table 7) are available for writing in the setup mode. When the required value is written to the registers of customizable
parameters, write 2 (instruction for “Saving”) in the instruction register. The accuracy of values for the stored parameters can
be checked by comparing the collections of customizable parameters and saved parameters. If collections are the same, new
values and settings shall be accepted and saved.
To reset the saved parameters to factory settings, write 3 (instruction for “Restoring to factory”) in the instruction
register.
Restart the unit for the saved settings to take effect. To restart via Modbus interface, write 1 (instruction for “Restarting”)
in the instruction register.
