Rules for Wiring Relay Coils
Use the output energize or “flip-flop” function once only for each relay coil.
Use the latch” and “unlatch” functions to control each relay coil - the first to set it
(S) and the second to reset it (R).

Output Relay Q: {Q1…{Q6 (depending on type)
Marker Relay M: {M1…{M16

Marker Relay (S marker): {S1…{S8 (1760-L18AWA)
Jumps: {:1…{:8 (1760-L18AWA)
The output signal follows immediately after the
input signal, and the relay acts as a contactor.

The relay coil switches state whenever the input signal changes
from 0 to 1. The relay behaves like a flip-flop.
