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 4.
For example when you enter the COPY 1 3 command, the relay responds,
Are

Answer Y <Enter> (for yes) to complete copying. The
resultant settings in Group 3 are overwritten by the settings in Group 1 and
pulse the SALARM Relay Word bit.
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)
