IP address
■IP address (Un\G64 to Un\G65)
Stores IP address on the own station set with GX Works3. (Page 31 Basic Setting) The stored values can be changed by
the IP address change function.
When IP address is 192.168.3.250: Un\G64 = K003250, Un\G65 = K192168
If the IP address is changed by the IP address change function, priority will be given to the IP address stored
by the IP address change function. To enable the set value in GX Works3, clear the IP address storage area.
Subnet mask pattern
■Subnet mask pattern (Un\G74 to Un\G75)
Stores subnet mask pattern on the own station set with GX Works3. (Page 31 Basic Setting) The stored values can be
changed by the IP address change function.
If the subnet mask pattern is changed by the IP address change function, priority will be given to the subnet
mask pattern stored by the IP address change function. To enable the set value in GX Works3, clear the IP
address storage area.
When subnet mask pattern is 255.255.255.0: Un\G74 = K255000, Un\G75 = K255255
