A
CPU module data backup/restoration function
The following is the list of special relay areas relating to the CPU module data backup/restoration function.
*1 There are restrictions on the firmware version of the CPU module and software version of the engineering tool. ( Page 747 Added
and Enhanced Functions)
File transfer function (FTP client)
The following is the list of special relay areas relating to the file transfer function (FTP client).
*1 There are restrictions on the firmware version of the CPU module and software version of the engineering tool. ( Page 747 Added
and Enhanced Functions)
*2 The Process CPU with firmware version "13" or later supports this special relay area.
Event history function
The following is the list of special relay areas relating to the event history function.
*1 There are restrictions on the firmware version of the CPU module and software version of the engineering tool. ( Page 747 Added
and Enhanced Functions)
No. Name Data stored Details Set by (setting
timing)
SM1350 CPU module data backup
status flag
*1
Off: Not being executed
On: Being executed
This relay turns on during the backup of the CPU
module.
S (Status change)
SM1351 CPU module data backup
execution request
*1
OffOn: Backup requested
OnOff: Backup completed
• At the timing when this relay turns from off to on,
the backup of the CPU module is executed.
• This relay turns off at the completion of the backup
of the CPU module.
S (Status change)/
U
SM1356 Retry status flag for CPU
module data automatic
backup
*1
Off: Not being executed
On: Being executed
This relay turns on during the retry of the automatic
backup of the CPU module.
S (Status change)
No. Name Data stored Details Set by (setting
timing)
SM1392 FTP client connection
status
*1*2
Off: Not connected
(disconnected)
On: Connected
This relay turns on when the connection with the FTP
server is established. This relay turns off when the
connection with the FTP server is cut off.
S (Status change,
END processing)
No. Name Data stored Details Set by (setting
timing)
SM1464 Event history logging
restriction status
*1
Off: Not restricted
On: Restricted
Turns on when the event history logging has been
restricted. The relay remains on even after the
restriction is lifted. Restricted modules can be
identified in SD1464 to SD1467. SM1466 turns on
when the event history logging of the CPU module is
restricted and the event category is error (minor
error), and SM1467 is turned on when the event
history logging of the CPU module is restricted and
the event category is information or warning.
S (Status change)
SM1466 Event history logging
restriction status of the CPU
module (minor error)
*1
Off: Not restricted
On: Restricted
Turns on when CPU module event history logging
whose event category is error (minor error) was
restricted. The relay remains on even after the
restriction is lifted.
S (Status change)
SM1467 Event history logging
restriction status of the CPU
module (information,
warning)
*1
Off: Not restricted
On: Restricted
Turns on when CPU module event history logging
whose event category is information or warning was
restricted. The relay remains on even after the
restriction is lifted.
S (Status change)
