Subnet Mask (Modifiable)

Displays the subnet mask for the module. A subnet mask “masks out” the network bits of the IP address by setting the bits in the mask to 1 when the network treats the corresponding bits in the IP address as part of the network or subnetwork address, or to 0 if the corresponding bit identifies the host. When an IP address is entered in the IP Address field, the subnet mask field automatically enters the default subnet mask for the IP address. For details about how to change the subnet mask from its default value, refer to Section 5.15.2.

Default Gateway (Modifiable)

Displays the default gateway for the 6E12X-26 and 6E13X-25. This field is not defined until an appropriate value is entered. For details about why and how to set the Default Gateway, refer to Section 5.15.3.

TFTP Gateway IP Addr (Modifiable)

Displays and allows the user to set the TFTP Gateway IP address for the 6E12X-26 and 6E13X-25. To set the TFTP Gateway IP address, refer to Section 5.15.4.

Module Date (Modifiable)

Contains a value that the module recognizes as the current date. To set a new module date, refer to Section 5.15.5.

Module Time (Modifiable)

Contains a value that the module recognizes as the current time. To enter a new time, refer to Section 5.15.6.

Screen Refresh Time (Modifiable)

Contains the rate at which the screens are updated. This setting determines how frequently (in seconds) information is updated on the screen. To enter a new update time, refer to Section 5.15.7.
