Precautions for Correct Use
Refer to the following manuals for precautions for correct use.
• NX-series CPU Unit Hardware User's Manual (Cat. No. W535)
• NX-series NX502 CPU Unit Hardware User's Manual (Cat. No. W629)
• NX-series NX102 CPU Unit Hardware User's Manual (Cat. No. W593)
• NX-series NX1P2 CPU Unit Hardware User's Manual (Cat. No. W578)

Operation
• In order to prevent unintended firmware update operation due to unauthorized operation of DIP
switch, take sufficient measures by means of locking the installation area and entrance manage-
ment, etc.
SD Memory Cards
• When using an SD Memory Card, make sure that the SD Memory Card is usable before use.
You can check if the SD Memory Card is usable or not by the _Card1Ready system-defined variable
and the SD PWR indicator.
• If the SD Memory Card is write-protected, writing with the Firmware Updater Writer is not possible.
• When performing firmware update, use the SD Memory Card in write-protected state.
• Do not format the SD Memory Card on a computer or CPU Unit.
Use the SD Memory Card Formatter provided by the SD Association when you format the SD Mem-
ory Card.
• Insert the SD Memory Card all the way.
Updating Firmware
• Do not remove the SD Memory Card during firmware update.
Doing so may damage the data in the SD Memory Card.
• Updating the firmware initializes the existing data such as various settings, user program, and varia-
bles in the CPU Unit.
• Do not turn OFF the power to the Controller while updating the firmware (when the BUSY indicator
is flashing).
While updating the firmware, the firmware in the built-in non-volatile memory in the CPU Unit is re-
written.
The firmware will not be updated normally if the power supply is turned OFF.
