Communications Interfaces
Communications Card
If your connection to the Ethernet card has an inactivity timeout, the Ethernet
card automatically closes the connection and changes to Access Level 0 when
the timeout expires.
ACCESS
Use the ACCESS command to change to Access Level 1. For example, if you
are at Access Level 0, the Ethernet card prompts you for the password and
moves you to Access Level 1 if you enter the password correctly. For
additional details on access level commands, see 2ACCESS.
DATE
Tab le 4.13 illustrates how to use the DATE command to view or set the date.
The DATE command displays the internal clock date. A setting in the host
determines the date format. In order to avoid confusion, the Ethernet card
displays the date format along with the date. For example, if you set the host
for a European style date, the Ethernet card displays the current date and the
date format text “dd/mm/yyyy.” The date format options are mm/dd/yyyy, dd/
mm/yyyy, and yyyy/mm/dd.
Use the DATE command with a date to set the internal clock date. Enter the
year in four-digit form. Enter the date in a form that matches the date form of
the host. Because there is no way to differentiate between mm/dd/yyyy and
dd/mm/yyyy for certain dates (02/03/2001 could be February 3 or March 2),
check the date format before entering the date. To see the date format, use the
DATE command.
DNPMAP
Use the DNPMAP command to display the data (object types, indices, default
variation and source) and controls (object type, indices and destination) that
are accessible via DNP3. The output of the DNPMAP command documents
the DNP3 data map in the SEL-421 to help with the configuration of the
DNP3 master.
If the DNPMAP setting is set to CUSTOM, then an additional integer
parameter corresponding to an assigned DNPMAP number (1
–5) must be
specified to view each custom DNP3 data map. For example, the command
DNPMAP 2 would be used to view the custom data map for DNP session 2. If
a DNPMAP number is not specified, a summary of DNP3 map settings for all
configured sessions will be displayed.
Summary and detailed map configurations are also available in the
DNPMAP.TXT and DNPMAPnn.TXT files from the Ethernet card FTP
interface. The individual file names associated with the detailed custom map
settings follow the DNPMAPnn.TXT naming convention.
Table 4.13 DATE Command
Command Description
DATE Display internal Ethernet card date.
DATE mm/dd/yyyy Set the date if the date format setting for the host is mm/dd/yyyy,
where mm is the month, dd is the day of month, and yyyy is the

DATE dd/mm/yyyy Set the date if the date setting for the host is dd/mm/yyyy.
DATE yyyy/mm/dd Set the date if the date setting for the host is yyyy/mm/dd.
