Step 9: In the Settings Explorer, click BESTlogicPlus Programmable Logic to open the logic diagram.
Click the Current tab. See Figure 13. Examine the 50-3 element. The Logic 0 connected to the
Block input indicates that the 50-3 element is never blocked.
Off-Page Inputs/Outputs are used to make connections between logic pages and help keep logic
diagrams free from clutter. The Trip output is connected to an Off-Page Output named 50-3 Trip.
This 50-3 Trip Off-Page Output is carried over to the Misc. Logic tab (Figure 14) where it
becomes an Off-Page Input. The 50-3 Trip Off-Page Input and several others are AND gated to
the Trip Bus Off-Page Output which becomes an Off-Page Input (Figure 15). The Trip Bus Off-
Page Input is connected to the Trip input of the Fault Trigger (FAULTTRIG) element to log a 50-
3 target and to record fault current magnitudes at the time of trip.
