Meaning
This relay stores information on whether an
RS-232 adapter is connected or not.
Connection of an RS-232 adapter is checked
at the time of initialization, and if it is
connected, this relay turns on. The on/off
status set during initialization is held until the
power is turned off and on again or the
system is reset.
• This flag is enabled when the time reserved
for communication processing is set in
SD315.
• Turns ON to delay the END processing by
the time set in SD315 in order to perform
communication processing.
(The scan time increases by the period set
in SD315.)
• Turns OFF to perform the END processing
without a delay of the time set in SD315
when there is no communication
processing. (Defaults to OFF)
• This relay indicates whether the CC-Link
module is started and all the data are
refreshed by the automatic CC-Link start
function.
• This relay is on when all the data are
refreshed by the automatic CC-Link start
function.
• Then the automatic CC-Link start function
is not activated, or when the refresh device
range is insufficient, this relay is turned off.
(If the refresh device range set for the
automatic CC-Link start function is
insufficient, all of the refresh is stopped.)
• This relay is on if an SFC program is
absent registered.
• This relay turns off if no SFC program is
present registered.
• The same value as in SM320 is set as the
initial value.
(This relay turns on when an SFC program
executed (stop) is registered.)
• Turning off this relay stops SFC program
executed (start) execution.
• Turning on this relay restarts SFC program
execution.
In the SFC setting of the PLC Parameter
dialog box, Initial start is set for the SFC
program start mode.
• At initial start: OFF
• At continued start: ON

effective
transition bit" of the SFC data device has not
been set.
transition effective
• This relay is off while the module is in the
continuous transition mode or during
continuous transition, and is on when
executed
continuous transition is not executed.
• This relay is always on while the CPU
transition
module is operating not in the continuous
transition mode.
