Meaning Explanation
• This relay turns on when an area outside a
file register range in a memory card is
range
accessed. (This relay is set at END
processing.)
range
• This relay is reset from a program.
• This relay turns on if latch data backup to
the standard ROM is not completed.
• This relay turns off when the backup is
completed.
• When latch data are backed up while this
relay is on, the backup data will be
restored at every power-on of the CPU
module.
• The backup data will be restored at every
power-on until the latch data are deleted or
the latch data are backed up again.
This relay turns on if a write error is detected
during writing to the program memory (flash
ROM). This relay turns off when a write
executed/normal
command is given.
This relay is on during writing to the program
memory (flash ROM) and turns off when the
executed writing is completed.
