Fanuc Power Mate i-D/H Maintenance Manual

E. DATA BACKUP
B63175EN/03
APPENDIX
544
Data in the Power Mate i includes the following:
Item Storage location
Parameter
SRAM on the memory module
Program
Ladder program
FROM on the memory module
User program of the macro executor
User program of the C executor
Data stored in the SRAM (hereafter called the SRAM data) on the
memory module is normally backed up by battery, so the data is not erased
even when the power to the Power Mate i is turned off. However, the data
may be lost because of, for example, a weak battery or printedcircuit
board replacement involving mounting and dismounting the memory
module. For this reason, a backup copy should always be saved on a
memory card or floppy disk after rewriting the data in the SRAM. For
maintenance purposes, data stored in the SRAM can be copied into the
builtin FROM of the Power Mate i.
CAUTION
Be sure to take a backup copy of the latest SRAM data onto
a memory card or floppy disk. If the latest data is not backed
up, the SRAM data cannot be restored when it is lost.
Since the FROM on the memory module is a nonvolatile memory, data
stored in the FROM is not erased even when the power to the Power Mate
i is turned off. Usually, the FROM contents are not rewritten by the
operator. However, be sure to take a backup copy of the FROM contents
in case that the memory module of the Power Mate i becomes faulty.
A backup copy may be created using the following methods:
(1)Taking a backup copy onto a flash memory card
(2)Copying data in the SRAM memory card and taking its backup copy
onto the hard disk of the PC
(3)Taking a backup copy of data onto a floppy disk by using the Handy
File
The data mentioned above can be saved on and restored from a flash
memory card. With the method using the boot system (SRAM DATA
BACKUP Screen in Appendix C.2.5), a backup copy of SRAM data can
be created. With the method using the Power Mate i main unit (see
SETTING/MAINTENANCE USING THE Power Mate i MAIN UNIT
in Appendix F.4), SRAM data and FROM data can be backed up in a
batch. For how to handle the flash memory card, see the description of
memory card handling in APPENDIX D.
