Operations
Backing Up MC Unit Data
Files to a Memory Card Set the DIP switch on the CPU Unit's front panel as shown below, and then
hold down the Memory Card power button for three seconds.
An MC Unit data file will be created and it will be written to the Memory Card
along with the other backup files.
When the Memory Card power button is pressed, the MCPWR indicator on
the CPU Unit's front panel will flash once and then remain lit while the data is
being written. The indicator will then turn OFF after writing is completed suc-
cessfully.
Restoring MC Unit Data
Files from a Memory Card The files on the Memory Card can be read and set in the MC Unit. Set the DIP
switch on the CPU Unit's front panel as shown below, and then turn ON the
power to the CPU Unit.
The MC Unit data file on the Memory Card will be read and it will be restored
to the MC Unit.
Note During the restoration, data is read from the Memory Card to the MC Unit's
internal RAM, and then the data is checked. If the data is normal, it is auto-
matically written to the flash memory. If the data is not normal, a system
parameters corrupted error (error code: 0001) will occur and the RAM will be
initialized. In that case, the data will not be written to the flash memory.
