5. Programming on the device5.4 Working with contacts and coilsYou can follow energized connections across all rungs by scrolling the display up anddown.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 themillisecond range due to the inherent technical delay of LCD dis-plays.5.4.15 JumpsJumps can be used for structuring a circuit diagram. They can replace the function of aselector 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 thel circuit diagram, for skipping rungs:Jump location and jump destination are located in the same circuit diagraml Function block editor, for skipping function blocks:Jump location is located in the circuit diagram and jump destination in the functionblock editorThe 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.Circuit diagram elements for jumps in the circuit diagramContact (N/O1))Numbers 001 up to 032CoilsNumbers 001 up to 032Coil function , , , ,1)can only be used as first leftmost contactFunction of jumpsIf 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 samenumber as that of the coil.l Coil = Jump when 1l Contact only at the first left-hand contact position = Jump destinationThe jump destination is always an N/O contact with the status 1.144 easyE4 11/18 MN050009 EN www.eaton.com
