• Immediately after a STOP request is made,
the coil output of the operation output is turned
OFF and the block is stopped.
• The status remains active.

(STOP after
transition)
• Normal operation is performed until the
transition condition is satisfied.
• When the transition condition is satisfied, the
end processing of the corresponding step is
performed.
At the same time, the transition destination
step becomes active and the block is stopped
before execution of the operation output.
• Immediately after a
STOP request is
made, the coil
output of the
operation output is
turned OFF and the
block is stopped.
• The status
becomes inactive.

• Immediately after a STOP request is made, the block is stopped
with the coil output of the operation output being held.
• The status remains active.
*: The held step indicates the step whose attribute has been set to the HOLD step (SC, SE, ST) and which is being held with the
transition condition satisfied.
