● Setting of Write Protect Switch
The write protect function is to prevent the overwriting of
parameters.
Write protection can be carried out using either the write
protection switch (SW1-2) (See Figure 6.3.1) or software
function with parameter setting. If either of these items is
activated, the overwriting of parameters will be prohibited.

● Setting of Address Switch (ADDRESS)
The device IP address can be set using either the
address switch (ADDRESS) (See Figure 6.3.2) or
software parameters.
The Address Switch (ADDRESS) is used to set the 4
th
octet (8 bits) of the IP address. The 1

rd
octets
of the IP address are set by software parameters. The
4

octet of the address which is set by this switch
(ADDRESS) is enabled when the Enable hardware
switch (SW3-1) is set to ON. When the Enable hardware
switch (SW3-1) is set to OFF, the 4
th
octet of the IP
address set by this switch (ADDRESS) is disabled, and
the 4th octet of the address set by software parameter is
enabled.
