For example, use the following command to set Remote Bit RB05:
COPY Command
Use the COPY j k command (see Table 7.13 ) 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 1 overwrite the settings in Group 3.
COUNTER Command (Counter Values)
The device generates the values of the 32 counters in response to the COU
command (see Table 7 .14).
DATE Command (View/Change Date)
Use the DATE command (see Table 7.15) to view and set the relay date. The
relay can overwrite the date you enter by using other time sources such as
IRIG. Enter the DATE command with a date to set the internal clock date.
