Restore
Transferring data from a Memory Card to the PCU is referred to as a restore.
Set the DIP switch on the front panel of the CPU Unit as shown below, and turn the power
supply of the CPU Unit from OFF to ON.
Through this operation, an PCU data file on the Memory Card is read and restored to the PCU.
When the power supply turns ON, the MCPWR LED on the front panel of the CPU Unit turns
ON and flashes once, and then turns ON when the data read is in progress. It turns OFF after
the data read is completed successfully.
PCU
When you restore data, the data are read from the Memory Card onto the RAM of the PCU, and
checked. If the operation is normal, the data are automatically written to the flash memory. If the
operation is not normal, a Special I/O Unit memory error (User data) (error code: 0010) occurs,
while the values on the RAM are initialized, and the data will not be written to the flash memory.
