Startup Settings and Maintenance Section 6-6
The amount of time required to back up data (the time the BKUP indicator will
be lit) will depend on the size of the user program, as shown in the following
table.
Note 1. The BKUP indicator will be lit when power is supplied to the CPU Unit.
2. Depending on the type of online editing that was performed, up to 1 minute
may be required to backup data.
3. I/O memory (including the DM, EM, and HR Areas) is not written to flash
memory. The data in these areas is backed up by a Battery for recovery
after power interruptions. The data may not be correctly recovered if a bat-
tery error occurs, If the Battery Error Flag (A40204) is ON, take appropriate
steps in the ladder program to set the contents of these areas as required.
4. 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 dis-
played in the transfer window after the transfer status for the program and
other data.

6-6-11 Startup Condition Settings
This function is supported only by the CS1-H, CJ1-H, or CJ1M CPU Units.
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 for these Units to
be initialized.
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.)
