Figure 98:Power flow display
In the power flow display, energized connections are thicker than non-
energized connections.
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. (
section , “Power flow display with Zoom function”, page 83).

4.5.15 Jumps
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 programs.
Jumps consist of a jump location and a jump destination (label).
Jumps exist in the
•
circuit diagram, for skipping rungs:
Jump location and jump destination are located in the same circuit
diagram
•
function block editor, for skipping function blocks:
Jump location is located in the circuit diagram and jump destination in the
function block editor
The use of jumps in the function block diagram is explained in Chapter
“Function blocks”
section 5.19, “LB, jump label”, page 213 and
section 5.18, “JC, conditional jump”, page 211.
The easy800 device allows the use of up to 32 jumps.
Circuit diagram elements for jumps in the circuit diagram
￫
If you change to the circuit diagram display but cannot change a
circuit diagram, first check whether the easy800 device is in
STOP operating mode.
￫
The power flow display does not show signal changes in the
millisecond range due to the inherent technical delay of LCD
displays.
