The SMARTCARD has 999 individual data block locations. Each
individual location from 1 to 499 can be used to store data until the
capacity of the SMARTCARD is used. The drive can support
SMARTCARDs with a capacity of between 4kB and 512kB.
The data block locations of the SMARTCARD are arranged to have the
following usage:

Table 9-1 SMARTCARD data blocks

Data Block
1 to 499 Read / Write
500 to 999 Read Only
'Differences from default' parameter sets will be much smaller than
whole parameter sets and thus take up a lot less memory as most
applications only require a few parameters to be changed from the
default setting.
The whole card may be protected from writing or erasing by setting the
read-only flag as detailed section 9.2.10 9888 / 9777 - Setting and
clearing the SMARTCARD read only flag on page 73.
Data transfer to or from the SMARTCARD is indicated by one the
following:
• Digitax ST: The decimal point after the fourth digit in the upper
display will flash.
• SM-Keypad Plus: The symbol 'CC' will appear in the lower left hand
corner of the display
The card should not be removed during data transfer, as the drive will
produce a trip. If this occurs then either the transfer should be
reattempted or in the case of a card to drive transfer, default parameters
should be loaded.

Transferring data

Data transfer, erasing and protecting the information is performed by
entering a code in Pr xx.00 and then resetting the drive as shown in
Table 9-2.

The data block contains the complete parameter data from the drive, i.e.
all user save (US) parameters except parameters with the NC coding bit
set. Power-down save (PS) parameters are not transferred to the
SMARTCARD.
