5. Programming on the device
5.4 Working with contacts and coils
Backward jumps cannot be executed due to the way in which
easyE4 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 :1/jumped area/contact :1,
Coil :1/jumped area/contact :1,
etc.
NOTICE
If rungs are skipped, the states of the coils are retained. The time of
started timing relays continues to run.
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.
