How to Use the Sequence Table Block
Specifying two or more Step Transitions (Branching)
A different destination step can be specified for each rule in a step, so more than one destination step can be
specified in a step. This feature allows control parameters, such as SP and PID settings, to be changed for dif-
ferent production models.

Processing moves to step 03 when the
condition of step 01 rule 01 is true.
Processing moves to step 02 when the
condition of step 01 rule 02 is true.
When there are two or more valid step transitions in a single step (the conditions for two or more rules control-
ling step transitions are met), processing will move to the step indicated by the lowest-numbered rule. The
step(s) indicated by higher-numbered rule(s) will not be executed after the step indicated by the lowest-num-
bered rule.
