Jumps can be used to optimise 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 "
a contact and coil. Jumps consist of a jump location and
a jump label.
Contact
:1 :8
to
(can only be used as
first leftmost contact)
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".
h
Backward jumps are not possible with the logic relay 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.:
