E. DATA BACKUPAPPENDIX
Data is copied onto the SRAM memory card in the same way as described
in Appendix E.2 above, then its backup copy is created on the hard disk
of the PC. A flash memory card cannot be used as the medium. Since the
SRAM memory card is backed up by battery, it is not suitable for data
For how to handle the SRAM memory card, see the description of
memory card handling in APPENDIX D.
Data items are backed up one by one using the Handy File. For the
operation method, see Sections 1.9 and 1.10, and Chapter 3.
SRAM data can be copied into the built–in FROM of the Power Mate i
without using a memory card or floppy disk. For the operation method,
see “SETTING/MAINTENANCE USING THE Power Mate i MAIN
UNIT” in Appendix F.4.
This method allows SRAM data to be easily restored if the data is
accidentally damaged during printed–circuit board replacement that does
not involve fuse replacement or memory module mounting/dismounting.
Also when printed–circuit board replacement involving memory module
mounting/dismounting is performed (that is, SRAM data is certainly
lost), SRAM data can easily be restored if its backup copy is created using
this method in advance.
1 This method does not mean that backup to a memory card
or floppy disk becomes unnecessary. Just with a backup
copy in the built–in FROM, data may not be able to be
retrieved if the Power Mate i memory module becomes
2 Data in the FROM can be rewritten a limited number of
times. This function is designed for data backup performed
at maintenance (about several hundreds times), and is not
assumed to be used for data rewritten periodically or
