10.7 Changing parameters by means of MODBUS
1. Write the value of the menu to be changed to the address 5000h using function 06.
2. Write the value of the submenu to be changed (where present), using function 06, to the
address 5001h.
3. Using function 6, write the value of the parameters to be changed to the address 5002h.
4. Perform function 16 at the address 5004h, with the number of the register corresponding
to the length of the parameter (see table).
5. In order to change another parameter in the same menu / submenu repeat step 4, or if
you wish to read a new parameter, repeat step 1.
6. In order to carry out changes to the parameters successfully, it is necessary to save these
in the EEPROM of the device.
For this purpose, execute the command in accordance with chapter Commands (use with
MODBUS function 06) (Page 199).
(Using function 6, write the value 5 to the address 2F03).
Step 1: Select menu 08
= 5000H (5000H - 0001H = 4FFFH)
= 5000H (5000H - 0001H = 4FFFH)
