For example, use the following command to set Remote bit RB05:
=>>
CON RB05 S <Enter>
COPY Command
Use the COPY j k command (see Table 7.12 ) to copy the settings of settings
Group j to the settings of settings Group k . The settings of settings Group j
effectively overwrite the settings of settings Group k . Parameters j and k can
be any available settings group number 1 through 3.
For example when you enter the COPY 1 3 command, the relay responds,
Are
you sure (Y/N)?
Answer Y <Enter> (for yes) to complete copying. The
settings in Group 3 are overwritten by the settings in Group 1.
COUNTER Command (Counter Values)
The device generates the values of the 32 counters in response to the COU
command (see Table 7.13 ).
DATE Command (View/Change Date)
Use the DATE command (see Table 7.14 ) to view and set the relay date.
The relay can overwrite the date entered by using other time sources such as
IRIG. Enter the
DATE command with a date to set the internal clock date.
Separate the month, day, and year parameters with spaces, commas, slashes,
colons, and semicolons. Set the year in 4-digit form (for dates 2000–2099).
Global setting DATE_F sets the date format.
ETH Command
The ETH command (Access Level 1) may be used to display the Ethernet port
(Port 1) status as shown in Figure 7.17 for the redundant fiber-optic (FX)
Ethernet
Port 1A
and
Port 1B
configuration. Copper Ethernet port is labelled as
TX. The non-redundant port response is similar.
