9-11-3 Operating Procedures
Backing Up PCU Data Files on Memory Card
Set the DIP switch on the front of the CPU Unit as shown in the following
table, and then press and hold the Memory Card power supply switch for
three seconds.
This creates a PCU data file and writes this files along with other backup files
to the Memory Card. When the power supply switch is pressed, the MCPWR
indicator on the front of the CPU Unit will flash once and then remain lit while
data is being written. The indicator will go out after all data has been written to
the Card.
Restoring PCU Data Files from Memory Card (Reading Data and Writing It to the Unit)
Set the DIP switch on the front of the CPU Unit as shown in the following
table, and turn ON the PLC.
This reads the PCU data file on Memory Card and restores the data to the
PCU.
Note When data is restored, it is read from Memory Card to PCU RAM
where it is checked. If the check ends successfully, the data is au-
tomatically written to flash memory. If the check fails, then a param-
eter corrupted error (error code: 0001) will be displayed, the RAM
will be initialized and nothing will be written to flash memory.
When power is turned ON, the MCPWR indicator on the front of the CPU Unit
will light, flash once, and then remain lit while data is being written. The indi-
cator will go out after all data has been written to the Card.
