IP Address Mode (P5.9.1.1)
Selectable alternatives are DHCP (Dynamic Host Configuration Protocol) and Fixed.

A fixed IP address is specified manually and does not change.
When the mode is changed from DHCP to Fixed, the addresses will read:
IP: 192.168.0.10
Subnet mask:255.255.0.0
Default gateway: 192.168.0.1
