Logic schemes can be selected from the Logic Select tab on the BESTlogic Screen. To access this
screen, select BESTlogic from the Screens pull-down menu. Then select the Logic Select tab. Select the
desired logic scheme to copy to User logic. The active logic scheme is shown in the User box. In Figure
7-6, FEEDER_1 has been selected to user logic.
Figure 7-6. BESTlogic Screen, Logic Select Tab.
CAUTION
Selecting a logic scheme to be active in BESTCOMS does not automatically
make that scheme active in the relay. See the paragraphs later in this section
titled Sending and Retrieving Relay Settings.
Custom Logic Schemes
A custom logic scheme can be created from scratch by copying NONE to active logic and then renaming
the logic. To rename a scheme, place the mouse pointer over the name shown in the User box. This will
highlight the current name. Simply choose a name that is appropriate for your application and type the
new name over the current name. Modifying one of the preprogrammed logic schemes after copying it to
active logic and renaming can also create a custom logic scheme. Preprogrammed logic schemes copied
to active logic with no name change are read-only schemes and cannot have their logic expressions
altered. Before modifying a logic scheme copied to active logic, the scheme must be assigned a unique
name of one to eight alphanumeric characters. This scheme is then referred to as a custom or user
programmable logic scheme because the variable expressions of the logic can be customized or created
from scratch to suit the needs of an application. A custom logic scheme may be revised many times, but
only the most recent changes are saved to active logic.
NOTE
A copied logic scheme must be renamed in order to become a custom logic
scheme. If it is not renamed, you will not be allowed to change the settings
associated with that scheme.
