Explanation
This register stores the index value of write count of the
*1
standard ROM (flash ROM) up to the present in 32-bit
binary. When the index value exceeds 100 thousand times,
"FLASH ROM ERROR" (error code: 1610) occurs. (The index
value will be counted even after it exceeds 100 thousand.)
*1 The write count does not equal to the index value.
(Since the maximum write count of the flash ROM has
been increased by the system, 1 is added to the index
value when the total write data size after the previous
count-up reaches about 1M byte.)
This register stores the cause of an error that occurred during
backup.
• 0 : No error
H
• 100 : Memory card or SD memory card not inserted
H
• 200 : Backup data size exceeded
H
• 300 : Write protection set to memory card or SD memory
H
card
• 400 : Memory card or SD memory card write error
H
• 500 : Backup data read error (program memory)
H
• 503 : Backup data read error (standard RAM)
H
• 504 : Backup data read error (standard ROM)
H
• 510 : Backup data read error (system data)
H
• 600 : Backup preparation was performed while latch data
H
was being backed up to the standard ROM.
• 601 : Backup preparation was performed during online
H
change.
• 602 : Backup preparation was performed with an FTP
H
client connected to and communicated with the CPU
module.
• 603 : Backup preparation was performed while the data
H
logging function was being executed.
• 605 : Backup preparation was performed while the project
H
data batch save/load function was being executed.
• 606 : Backup preparation was performed while any
H
specified file or folder was being deleted using a display
unit.
• 607 : Backup preparation was performed while the iQ
H
Sensor Solution function (data backup/restoration) was
being executed.
• 608 : Backup preparation was performed while the file
H
transfer function (FTP client) was being executed.
• 609 : Backup preparation was performed while the CPU
H
module data backup/restoration function was being
executed.
• 700 : A security key is set to the CPU module.
H
• 701 : Backup preparation was performed when "Execution
H
Program Protection Setting" was enabled with a block
password.
Stores the current backup status.
• 0: Before backup
• 1: Being prepared
• 2: Ready
• 3: Being executed
• 4: Completed
• FF: Backup error
• This register stores the progress of backup to the memory
card or SD memory card in percentage (0 to 100%).
• "0" is stored at the start of backup.
