TableApp.3 Special relay
Meaning
• Turns ON when an SFC program is registered.
• OFF when an SFC program is not registered.
• Initial value is set at the same value as SM320.
(Goes ON automatically if SFC program is present.)
executed (stop) • Turn this relay from ON to OFF to stop program
execution.
(start) • Turn this relay from OFF to ON to resume program
execution.
• The SFC program starting mode in the SFC setting
of the PLC parameter dialog box is set as the initial
value.
AT initial start: OFF
At continued start: ON
Set the presence/absence of continuous transition for
not effective
the block where "Continuous transition bit" of the SFC
data device has not been set.
effective
• OFF during operation in the continuous transition
mode or during continuous transition, and ON when
executed continuous transition is not executed.
• 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
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.
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.
• Select the device status at the time of switching from
turned OFF (cleared) STOP to program write to RUN.(All devices except
the 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.?
• When this relay turns OFF, all active steps are
performed. forcibly terminated to terminate the block.
• 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
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.
• Indicates whether the normal SFC program is being
executed or not.
• Used as an SFC control instruction execution
interlock.
• Indicates whether the program execution
management SFC program is being executed or not.
• Used as an SFC control instruction execution
interlock.
• The status of the intelligent function module access
instruction executed immediately before is stored.
(This data is overwritten when the intelligent function
module access instruction is executed again.)
• Used by the user in a program as a completion bit.
