Section 5-2
If the IOM Hold Bit (A50012) is ON and the PLC Setup is set to maintain
the IOM Hold Bit Status at Startup when the backup files are written, the
status of I/O memory data will be maintained when data is read from the
Memory Card.
If the Forced Status Hold Bit (A50013) is ON and the PLC Setup is set to
maintain the Forced Status Hold Bit Status at Startup when the backup
files are written, the status of force-set and force-reset bits will be main-
tained when data is read from the Memory Card.

An error will not occur in the CPU Unit even if this file is missing when data
is transferred from the Memory Card to I/O memory, but an error will occur
in the Unit or Board if the data is not restored. Refer to the operation man-
