Function of jumps
If the jump coil is triggered, the rungs after the jump coil are no longer
processed. 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 destination is always an N/O contact with the status 1.
Power flow display of skipped area
Jumped sections are indicated by the coils in the power flow display. All coils
after the jump coil are shown with the symbol of the jump coil.
Example for jumps
A selector switch is used to select two different sequences.
• Sequence 1: Switch on motor 1 immediately.
• Sequence 2: Activate barrier 2, wait time, then switch on motor 1.
Contacts and relays used:
•
I1 sequence 1
• I2 sequence 2
• I3 guard 2 moved out
• I12 motor-protective circuit-breaker switched on
• Q1 motor 1
• Q2 guard 2
• T 01 wait time 30.00 s, on-time
• D01 Text “Motor protective circuit breaker tripped”

1) Can only be used as first contact on the left
￫
Backward jumps cannot be executed due to the way in which
easy800 works. 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 is also skipped.
Multiple usage of the same jump coil and the same contact is
possible as long as this is done in pairs, this means:
• Coil Ä:1/jumped area/contact :1,
• Coil Ä:1/jumped area/contact :1,
etc.
CAUTION
If rungs are skipped, the states of the coils are retained.
The time of started timing relays continues to run.
