Important: If programs are written that continuously write information to
the drive, care must be taken to properly format the block
transfer. If attribute 10 is selected for the block transfer, values
will be written only to RAM and will not be saved by the drive.
This is the preferred attribute for continuous transfers. If
attribute 9 is selected, each program scan will complete a write
to the drive’s non-volatile memory (EEprom). Since the
EEprom has a fixed number of allowed writes, continuous
block transfers will quickly damage the EEprom. Do Not assign
attribute 9 to continuous block transfers. Refer to the individual
communications adapter User Manual for additional details.
