BE1-CDS220 BESTlogic Programmable Logic 7-7
When a custom logic scheme is required, programming time can be reduced by copying a
preprogrammed scheme into the active logic. The logic scheme can then be modified to meet the specific
application.
The Active Logic Scheme
Digital, multifunction relays must have an active logic scheme in order to function. All Basler Electric
multifunction relays are delivered with a default, active logic loaded into memory. The default, active logic
scheme for the BE1-CDS220 is named BASIC-87. If the function element configuration and output logic of
Basic Transformer Logic Scheme meets the requirements of your application, then only the operating
settings (power system parameters and threshold settings) need to be adjusted before placing the relay in
service.
If you wish to modify the scheme, it must be saved under a different name than that found in the logic
library (read only files). Any of the preprogrammed logic schemes discussed in Section 8, Application, can
be copied to the active logic and customized, or used as is. To copy a logic scheme into active logic,
select the scheme from the BESTCOMS logic library and upload it to the relay. To modify the
preprogrammed scheme, it is necessary to enter a unique name for the new logic before modifying the
settings. Naming the new logic distinguishes it from the preprogrammed logic scheme. After a
preprogrammed logic scheme is uploaded to the relay from BESTCOMS, it can also be renamed with the
SL-N<name> and customized using ASCII commands.
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 Active Logic (Internal Logic). The active logic scheme is shown in the Logic
Name box. In Figure 7-5, BASIC-TX has been selected as the user logic.

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.
