Continuous transition
prevention flag
OFF : When transition is
executed
ON : When no transition
• OFF during operation in the continuous transition
mode or during continuous transition, and ON when
continuous transition is not executed.

Output mode at block
stop
OFF : OFF
ON : Preserves
Select whether the coil outputs of the active steps are
held or not at the time of a block stop.
• As the initial value, the output mode at a block stop in
the parameter is OFF when the coil outputs are OFF,
and ON when the coil outputs are held.
• All coil outputs go OFF when this relay is OFF.
• Coil outputs are preserved when this relay is ON.

OFF : Clear device
ON : Preserves device
Selects the device status when the stopped CPU is run
after the sequence program or SFC program has been
modified when the SFC program exists.

Output during end step
execution
OFF : Hold step output
turned OFF (cleared)
ON : Hold step output held
• Select the device status at the time of switching from
STOP to program write to RUN.(All devices except
the step relay)

Operation mode for
low speed execution
type program
OFF : Asynchronous mode
ON : Synchronous mode
Select whether the low speed execution type program
will be executed in the asynchronous mode or in the
synchronous mode.
• Asynchronous mode (this relay is turned OFF.)
Mode in which the operation of the low speed
execution type program is performed continuously
within the excess time.
• Synchronous mode (this relay is turned ON.)
Mode in which the operation of the low speed
execution type program is not performed
continuously and operation is performed from the
next scan if there is excess time.
