• The SFC program starting mode in the SFC setting
of the PLC parameter dialog box is set as the initial

ON : Resume start
AT initial start: OFF
At continued start: ON
OFF : Continuous transition
Set the presence/absence of continuous transition for

the block where "Continuous transition bit" of the SFC
ON : Continuous transition
data device has not been set.
effective
• OFF during operation in the continuous transition
OFF : When transition is mode or during continuous transition, and ON when
executed continuous transition is not executed.
ON : When no transition • Always ON during operation in the no continuous
transition mode.
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
OFF : OFF
the parameter is OFF when the coil outputs are OFF,
ON : Preserves
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.
Selects the device status when the stopped CPU is run
OFF : Clear device
after the sequence program or SFC program has been
ON : Preserves device
modified when the SFC program exists.
OFF : Hold step output Select the device status at the time of switching from
turned OFF (cleared) STOP to program write to RUN.(All devices except the
ON : Hold step output held step relay)
Select whether clear processing will be performed or
not if active steps other than the ones being held exist
in the block when the end step is reached.?
OFF : Clear processing is • When this relay turns OFF, all active steps are
performed. forcibly terminated to terminate the block.
ON : Clear processing is not • When this relay is ON, the execution of the block is
performed. continued as-is.
• If active steps other than the ones being held do not
exist when the end step is reached, the steps being
held are terminated to terminate the block.
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
OFF : Asynchronous mode execution type program is performed continuously
ON : Synchronous mode 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.
• Indicates whether the normal SFC program is being
OFF : Not executed executed or not.
ON : Being executed • Used as an SFC control instruction execution
interlock.
• Indicates whether the program execution
OFF : Not executed management SFC program is being executed or not.
ON : Being executed • Used as an SFC control instruction execution
interlock.
• The status of the intelligent function module access
ON indicates completion of instruction executed immediately before is stored.
intelligent function module (This data is overwritten when the intelligent function
access module access instruction is executed again.)
• Used by the user in a program as a completion bit.
Indicates execution status of the S(P).GINT instruction.
OFF : Not executed
• Turned OFF before the instruction is executed.
ON : Execution completed
• Turned ON after the instruction is completed.
