4-3
Saving Data
Transferred position data and system parameters are written to internal MC
Unit memory where they will be used, but they will be lost if MC Unit power is
turned OFF or the Unit is restarted. The data must be stored in flash memory
using the command area to save the data in the MC Unit.
Once the data is saved, it is stored in internal MC Unit flash memory. The data
in flash memory will be used the next time MC Unit power is turned ON or the
Unit is restarted.
Note
1.
Data that has been saved is automatically read to internal memory from
flash memory when MC Unit power is turned ON or the Unit is restarted.
2.
Do not turn MC Unit power OFF or restart the Unit while data is being
saved, or flash memory in the MC Unit may be damaged.
The number of times that flash memory writes has a limited service life.
Data can be written up to 100,000 times.
3.
Do not operate the Teaching Box while saving data to flash memory.
4-3-1
Execution
The command area is used to save position data and system parameters to
flash memory. Data is saved by specifying the address in control code (C) of
the IOWR instruction and transferring the specified data to the MC Unit.
Writing position data to flash memory: Address 6100 (17D4 hex)
Writing system parameters to flash memory: Address 6101 (17D5 hex)
Refer to
Section 3-6 Command Area
for details on the command area.
4-3-2
Command Specifications
This section briefly describes the IOWR instruction specifications when the
command area is executed. Refer to
4-2-1 IOWR: INTELLIGENT I/O WRITE
for details.
