A
*1 There are restrictions on the firmware version of the supported CPU module and software version of the engineering tool. ( Page
1008 Added and Enhanced Functions)
*2 There are restrictions on the firmware version of the supported CPU module and software version of the engineering tool. ( Page

For the R00CPU, R01CPU, and R02CPU, the operation setting status is always set to "program file/FB file/global label setting file"
regardless of whether this relay is on or off.
*3 Only the standard program is supported.
SM240 No.1 CPU reset flag Off: CPU No.n not being
reset
On: CPU No.n in reset
mode
• This relay switches to off when the CPU
module of the CPU No.1 is not being
reset.
• This relay is on while the CPU module of
the CPU No.1 is being reset (including the
case when the CPU module is removed
from the base unit). Other CPUs also
enter into reset mode.
S (Status change) ALL
SM241 No.2 CPU reset flag • This relay switches to off when the CPU
module of the CPU No.2 is not being
reset.
• This relay is on while the CPU module of
the CPU No.2 is being reset (including the
case when the CPU module is removed
from the base unit). Errors occur in the
other CPU modules.
S (Status change) ALL
SM242 No.3 CPU reset flag • This relay switches to off when the CPU
module of the CPU No.3 is not being
reset.
• This relay is on while the CPU module of
the CPU No.3 is being reset (including the
case when the CPU module is removed
from the base unit). Errors occur in the
other CPU modules.
S (Status change) ALL
SM243 No.4 CPU reset flag • This relay switches to off when the CPU
module of the CPU No.4 is not being
reset.
• This relay is on while the CPU module of
the CPU No.4 is being reset (including the
case when the CPU module is removed
from the base unit). Errors occur in the
other CPU modules.
S (Status change) ALL
SM384 System operation setting
request
Off: Request accepted
On: Request submitted
• This relay is turned from off to on to send
a setting request and write/delete data to/
in the setting storage area (system
memory) with the value set in SD384.
• Regardless of whether it was successful
or not, this relay turns off when the setting
request is accepted.
U/S (Status change) Rn
*1
RnP
*1
RnSF
*1*3
SM385 System operation setting
error
Off: No error
On: Error
• This relay turns on when writing into the
setting storage area (system area) fails.
S (Status change) Rn
*1
RnP
*1
RnSF
*1*3
SM386 Program restoration
information write status
LED control setting mode
Off: LED flashing
On: Without LED flashing
• This relay indicates the LED control
setting status of program restoration
information.
S (Initial) Rn
*1
RnP
*1
RnSF
*1*3
SM387 Program restoration
information write status
Off: All written
On: Not all written
• This relay indicates the write status of
program restoration information in the
CPU module.
• This relay turns off when all program
restoration information is written.
• This relay turns on if there is any program
whose program restoration information is
not in the CPU module.
S (Status change) Rn
*1
RnP
*1
RnSF
*1*3
SM388 File batch online change
operation setting status
Off: Program file only
On: Program file/FB file/
global label setting file
This relay indicates the operating status of
the file batch online change.
S (Status change) Rn
*2
RnP
*1
No. Name Data stored Details Set by (setting timing) CPU
