Wiring with the logic relay

h The coil functions
negated, cycle pulse falling, rising edge) must only be used
once for each relay coil. The last coil in the circuit diagram
determines the status of the relay.
When controlling a contactor or relay, the control coil
is only present once. Create parallel circuits or use Set,
Reset as a coil function.
Rules for wiring relay coils
To ensure a clear overview of all relay states only assign the
same coil function once to a relay (
retentive coil functions such as
times if required by the circuit diagram logic.
Exception: When using jumps to structure a circuit diagram,
this coil function can also be used effectively several times.
Relay with contactor function
The output signal follows immediately after the input signal
and the relay acts as a contactor.
