4.7.1 Precautions for using a CompactFlash card
This section explains the precautions for using the CompactFlash card.
(1) Available CompactFlash cards
Use a CompactFlash card listed in Section 2.3. ( Section 2.3 Connection System
Equipment)
Failure to do so may cause a problem such as data corruption in the CompactFlash
card and system stop.
(2) When a CPU module is powered OFF or reset while writing data to a
CompactFlash card, the processing to write data to the CompactFlash card
may not be completed. It may cause a loss of data during DB buffering,
corruption of data in the CompactFlash card that is being accessed, or
occurrence of a file system error. The file is automatically recovered when the
MES interface module is powered ON again, but it will not succeed in some
cases.
The operation, powering OFF or resetting the CPU module after stopping file access,
should be considered. For the important data, create backups in other media
periodically.
Section 4.7.2 (1) Stopping file access
(3) When removing or replacing the CompactFlash card
(a) Be sure to stop file access before removing or replacing the CompactFlash card.
( Section 4.7.2 Installation/removing the CompactFlash card)
(b) Not doing so may cause the data corruption in the CompactFlash card being
accessed or a file system error.
(c) If an error occurs in the CompactFlash card, restore the card.
(d) The setting of information linkage function is saved to the CompactFlash card.
When necessary, write those settings to the CompactFlash card after replacing
the card.
(4) CompactFlash card diagnostic time
The MES interface module diagnoses (such as file restoration) the installed
CompactFlash card when:
1) Powering ON the programmable controller from OFF or resetting the
programmable controller CPU
2) Installing the CompactFlash card during power-on
(5) About a CompactFlash card format
(a) For the CompactFlash card format, use the formatting function of MES Interface
Function Configuration Tool.
