2-6-2 Step transition
The process of transferring the active state from one step to another is called “transition.” When the current step is active and
the transition condition for the next step is turned on, the current step is deactivated and the next step is activated.
(1) Single-flow transition
In the example shown below, a transition to S003 occurs when S002 is active and both inputs of transition condition INP1 and
INP2 are set to 1.

(2) Divergence of sequence selection
A single step has two or more step branches, one of which is selected for transition. A maximum of 32 branches are allowed.
A branch to “S010” occurs when “S013”
is active and “T006” is set to “1.”
Notes:
The left-hand side step “S010” is selected when both “T006” and “T007” are set to 1 at the same time.
