Navigation / Anchor Lights Toggle Logic using two
Momentary Input Signals
This circuit configuration type operates Navigation lights and Anchor light loads using two
separate "Discrete I/O" (Momentary) inputs. One input for "Navigation Lights" and one for
"Anchor Light". When "Navigation Lights" input is commanded both "Navigation Lights" and
"Anchor Light" ECBs turn On. When "Anchor Light" input is commanded "Anchor Light" ECB
turns On. When "Anchor Light" input is commanded while "Navigation Lights" ECB is On, the
"Navigation Lights" ECB is turned Off and "Anchor Light" ECB remains On. In this example,
"Discrete I/O 1" is used for "Navigation Lights" and "Discrete I/O 2" is used for "Anchor Light".
Step 1:
Choose appropriate output rules for the "Logic Elements" that will make this circuit possible.
Where 0 is Off and 1 is On, attention to the logic output correlation to the input combination
must be paid for proper operation. Notice that the output for the "Logic Element" #1 (Used for
Navigation Lights) will turn On therefor Toggling the ECB in two states, first, with "Discrete I/O
1" and also with "Discrete I/O 2" if the "Toggle Output 1" is already in the On state, therefore
toggling the ECB Off. The same occurs for "Logic Element #2" (Used for Anchor Lights). In this
manner each opposite input or "Discrete I/O" cancels the other.
