Wiring with EZ

Jumps Jumps can be used to optimize the structure of a circuit
diagram or to implement the function of a selector switch.
Jumps can be used for example to select whether manual/
automatic operation or other machine programs are to be set.
You integrate
:1 jumps into your circuit in the form of a
contact and coil. Jumps consist of a jump location and a jump
label.
Function
If the jump coil is triggered, the rungs after the jump coil are
no longer processed. The states of the coils before the jump
will be retained, unless they are overwritten in rungs that were
not missed by the jump. Jumps are always made forwards, i.e.
the jump ends on the first contact with the same number as
that of the coil.
• Coil = jump when 1
• Contact only at the first leftmost contact = Jump label
The Jump label contact point is always set to “1”.

J
Backward jumps are not possible with EZ due to the way it
operates.
If the jump label does not come after the jump coil, the jump
will be made to the end of the circuit diagram. The last rung
will also be skipped.
Multiple use of the same jump coil and jump contact is
possible as long as this is implemented in pairs, i.e.:
Coil
Ä:1/jumped section/Contact:1, Coil Ä:1/jumped
section/Contact
:1 etc.
