Meaning
Select whether the coil outputs of the active
steps are held or not at the time of a block
stop.
• The initial value is set to off when the
output mode at a block stop is off in the
OFF : OFF
parameter setting, and it is set to on when
ON : Preserves
the coil outputs are set to be held.
• When this relay is turned off, all coil outputs
are turned off.
• When this relay is turned on, the coil output
state is held.
Select the device status at the time of
OFF : Clear device switching from STOP to program write, and
ON : Preserves device then to RUN. (All devices except the step
relay)
OFF : Hold step output
turned OFF If this relay is off, the coil output turns off
(cleared) when the step held after transition (SC, SE, or
ON : Hold step output ST) reaches the end step.
held
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
OFF : Clear processing
are forcibly terminated to terminate the

block.
ON : Clear processing
• When this relay is ON, the execution of the
is not performed.
block is 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 : Asynchronous
off.) The operation of the low-speed
mode
execution type program is performed
ON : Synchronous
continuously within an excess time.
mode
• Synchronous mode (this relay is turned
on.) The operation of the low-speed
execution type program is not performed
continuously, but performed from the next
scan, even if there is excess time.
• This relay stores the information on
whether the normal SFC program is in
OFF : Not executed
execution or not.
ON : Being executed
• Used as an interlock for execution of the
SFC control instruction.
• This relay stores the information on
whether the SFC program for program
OFF : Not executed execution management is in execution or
ON : Being executed not.
• Used as an interlock for execution of the
SFC control instruction.
• This relay stores the status information on
the intelligent function module access
instruction that was just executed. (This
ON indicates completion
data is overwritten if the intelligent function
of intelligent function
module access instruction is executed
module access
again.)
• Used by the user in a program as a
completion bit.
