Figure 4-2. BESTlogic Function Element Screen, Setting Group Selection
At the top center of the BESTlogic Function Element screen is a pull-down menu labeled Logic. This
menu allows viewing of the BESTlogic settings for each preprogrammed logic scheme. A custom logic
scheme must
be created and selected in the Logic pull-down menu at the top of the screen before
BESTlogic settings can be changed. See Section 7, BESTlogic Programmable Logic.
Enable the Setting Group Selection function by selecting its mode of operation from the Mode pull-down
menu. To connect the functions 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.
