Open “Single DECS-400 Without PSS” Logic Scheme for Editing
1. Open the “Single DECS-400 Without PSS”
logic scheme in BESTCOMS by clicking
File, Open Default Scheme…. When the
Open Default Logic Scheme window opens,
click the button labeled “Single DECS-400
Without PSS” (see Figure 120). Click the
Yes button in the warning dialog box to
continue opening the logic scheme. Once
the logic scheme has been opened, a
second dialog box will appear. Click the OK
button.
2. Access the DECS Logic window by clicking
the Logic button on the BESTCOMS
toolbar.
3. To view the active logic scheme (DECS
Logic Viewer), click the View Logic button in
the DECS Logic window.
Figure 120. Open Default Logic Scheme Window
Table 24 lists the logic associations of the modified “Single DECS-400 Without PSS” scheme. Lined out
entries in the list indicate logic associations that will be deleted. Bold entries in the list indicate logic
associations that will be added later in this example.
