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.
• The initial value is set to off when the
output mode at a block stop is off in the
parameter setting, and it is set to on when
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.

Clear processing
mode when end
step is reached
OFF : Clear processing
is performed.
ON : Clear processing
is not performed.
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 forcibly terminated to terminate the
block.
• When this relay is ON, the execution of the
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.

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.) The operation of the low-speed
execution type program is performed
continuously within an excess time.
• 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 status information on
the intelligent function module access
instruction that was just executed. (This
data is overwritten if the intelligent function
module access instruction is executed
again.)
• Used by the user in a program as a
completion bit.
