To connect the function's inputs, select the button for the corresponding input in the BESTlogic Function
Element screen. The BESTlogic Expression Builder screen will open. Select the expression type to be
used. Then, select the BESTlogic variable, or series of variables to be connected to the input. Select
Save when finished to return to the BESTlogic Function Element screen. For more details on the
BESTlogic Expression Builder, see Section 7, BESTlogic Programmable Logic. Select Done when the
settings have been completely edited. Trigger settings for fault reports are made using the SG-TRIGGER
(settings-general, trigger) command.
Table 6-12 lists the function's trigger settings.

SG-TRIGGER Command
Purpose: Read/Set fault reporting trigger logic expressions.
Syntax: SG-TRIGGER[=<TRIP trigger logic>,<PU trigger logic>,<LOGIC trigger logic>]
Comments: The BESTlogic rules for input logic apply to the definition of the <trigger logic> which only
allows OR and NOT operators in the Boolean logic equation.
Example 1. Make the following BESTlogic settings to the Fault Recording function. Refer to
Figure 6-12.
Tripped: BFT+VO11
Picked up: 79LO+VO12
Logic: 79SCB
