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).

Instruction Type Representation in Pico
Output Relay Q {Q1…{Q6 (depending on type)
Marker Relay M {M1…{M16, {N1…{N16
Text Display Relay D {D1…{D16
Expansion or Marker Relay {S1…{S8 (1760-L18xxx)
Jumps {:1…{:8 (1760-L18xxx)
The output signal follows immediately after the
input signal, and the relay acts as a contactor.
