Precautions for Correct Use
When you reuse the existing various settings, user program, and values of variables in the CPU
Unit, make sure to back them up before updating the firmware, and restore them after the up-
date.
SD Memory Cards
When you create a Memory Card for updating firmware, all data on the SD Memory Card are deleted,
and it becomes an SD Memory Card dedicated for updating firmware.
When you create a Memory Card for updating firmware, separately save the data on the SD Memory
