z Network Filter Settings
This setting restricts the IP addresses allowed to access this module. The initial value
permits all IP addresses to access this module. This setting is referenced from all
functions that correspond to higher-level link service functions via Ethernet, such as
remote programming service and FTP server.
z CPU Operation Restriction
Use this setting if you want to protect higher-level link services.
CPU operation restriction can be used to protect operating mode switching, log
acquisition and other CPU operations that do not use WideField3, depending on the
combination of various access routes and CPU operation permission groups.
