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 contact point will always be set to 1

h Backward jumps are not possible with the display system
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.
If a jump destination is not present, the jump is made to
the end of the circuit diagram.
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 range/Contact:1,
Coil
Ä
:1/jumped range/Contact :1 etc.
Attention!
If rungs are skipped, the states of the coils are retained.
The time value of timing relays that have been started will
continue to run.
