You can follow energized connections across all rungs by scrolling the display up and
down.
The power flow display indicates at the bottom right the controller is in RUN mode.
The power flow display does not show signal changes in the
millisecond range due to the inherent technical delay of LCD dis-
plays.
Jumps can be used for structuring a circuit diagram. They can replace the function of a
selector switch, for example, for Manual/Automatic mode or for different machine pro-
grams.
Jumps consist of a jump location and a jump destination (label). Jumps exist in the
circuit diagram, for skipping rungs:
l
Jump location and jump destination are located in the same circuit diagram
Function block editor, for skipping function blocks:
l
Jump location is located in the circuit diagram and jump destination in the function

The use of jumps in the function block diagram is explained in → "LB - Jump label",
page 391 and → "JC - Conditional jump", page 386.
The easyE4 device allows the use of up to 32 jumps.

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
l
Contact only at the first left-hand contact position = Jump destination
l
The jump destination is always an N/O contact with the status 1.
