Jump Transition - Mitsubishi Electric MELSEC-Q Series Programming Manual

Jump transition

A "jump transition" is a jump to a specified step within the same block which occurs when the transition condition is satisfied.
SFC diagram
There are no restrictions regarding the number of jump transitions within a single block.
In the parallel transition format, only jumps in the vertical direction are possible at each of the branches.
Ex.
Jump transition program in vertical direction from branch to coupling
A program of a jump transition to another vertically branched ladder, a jump transition for exiting from a parallel branch, or a
jump transition to a parallel branch from outside a parallel branch cannot be created.
Ex.
Program for exiting from parallel branch (cannot be designated)
Do not specify a jump transition to the current step when the transition condition is satisfied as shown below.
Description
When condition "b" is satisfied at step "n" execution, step "n" (operation output [A]) is
deactivated, and processing proceeds to step "m".
