Chapter 4. Ladder Diagram (LD) ProgrammingGFK-2950C February 2018 2074.11.4 JumpNDescription Always associated with... MnemonicNested form of Jump instruction. a LABELN instruction JUMPNA JUMPN instruction causes a portion of the program logic to be bypassed. Program executioncontinues at the LABELN specified in the same block. Power flow jumps directly from the JUMPN tothe rung with the named LABELN.When the Jump is active, any functions between the jump and the label are not executed. All coilsbetween JUMPN and its associated LABELN are left at their previous states. This includes coilsassociated with timers, counters, latches, and relays.Any JUMPN can be either a forward or a backward jump, i.e., its LABELN can be either in a further orprevious rung. The LABELN must be in the same block.Note: To avoid creating an endless loop with forward and backward JUMPN instructions, abackward JUMPN should contain a way to make it conditional.A JUMPN and its associated LABELN can be placed anywhere in a program, as long as the JUMPN /LABELN range:■ does not overlap the range of a MCRN / ENDMCRN pair.■ does not overlap the range of a FOR_LOOP / END_FOR pair.Nothing can be connected to the right side of a JUMPN instruction.OperandsParameter Description OptionalLabel (????) Label name; the name assigned to the destination LABEL(N). No
