Logic Command/Status Words

Appendix B provides information on Logic Command and Logic Status Words.

Important: If block transfers are programmed to 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
tranfers. If attribute 9 is selected, each program scan will complete a write
to the drives 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.
