when they are written to the CPU Unit. I/O memory (including the DM, EM,
and HR Areas), however, is not written to flash memory. The DM, EM, and HR
Areas can be held during power interruptions with a battery. If there is a bat-
tery error, the contents of these areas may not be accurate after a power inter-
ruption. If the contents of the DM, EM, and HR Areas are used to control
external outputs, prevent inappropriate outputs from being made whenever
the Battery Error Flag (A40204) is ON.
Note The CS1G/H-CPU@@ (-V1) and CJ1@-CPU@@ CPU Units do not
support the flash memory functions.
Note A backup status will be displayed in a Memory Backup Status Window by the
CX-Programmer when backing up data from the CX-Programmer for transfer
operations other than normal data transfers (PLC/Transfer). To obtain this
window, setting to display the backup status dialog box must be checked in
the PLC properties and the window must be selected from the View Menu.
For normal transfer operations, the backup status will be displayed in the
transfer window after the transfer status for the program and other data.

Some Units and Inner Boards require extensive time to start up after the
power supply is turned ON, affecting the startup time of the CPU Unit. The
PLC Setup can be set so that the CPU Unit will start without waiting for these
Units to be initialized.
Note The CS1G/H-CPU@@ (-V1) and CJ1@-CPU@@ CPU Units do not support the
flash memory functions.
This setting applies to the ITNC-EIS01-CST and ITNC-EIX01-CST Open Net-
work Controller-CS1 Bus Interface Units. (There are currently no Inner Boards
that are applicable as of October 2001.)
This function is controller by setting the Startup Condition and Inner Board
