Issue Number: 3

'Boot' mode is saved to the card, but when the card is read, the value of
Pr

11.042

is not transferred to the drive.

9.3.5 Booting up from the SMARTCARD on every

power up (Pr mm.000 = 2001)

It is possible to create a bootable parameter data block by setting
Pr

mm.000

to 2001 and initiating a drive reset. This data block is created

in one operation and is not updated when further parameter changes are
made.
Setting Pr

mm.000

to 2001 will overwrite the data block 1 on the card if it

already exists.

9.3.6 800yy - Comparing the drive full parameter set

with the SMARTCARD values

Setting 8yyy in Pr

mm.000

, will compare the SMARTCARD file with the

data in the drive. If the compare is successful Pr

mm.000

is simply set to

0. If the compare fails a 'Card Compare' trip is initiated.

9.3.7 700yy / 9999 - Erasing data from the

SMARTCARD values

Data can be erased from the SMARTCARD either one block at a time or
all blocks in one go.
•

Setting 7yyy in Pr

mm.000

will erase SMARTCARD data block yyy

•

Setting 9999 in Pr

mm.000

will erase all SMARTCARD data blocks

9.3.8 9666 / 9555 - Setting and clearing the

SMARTCARD warning suppression flag

If the option modules installed to the source and destination drive are
different or are in different slots the drive will produce a 'Card Option' trip.
If the data is being transferred to a drive of a different voltage or current
rating a 'Card Rating' trip will occur. It is possible to suppress these trips
by setting the warning suppression flag. If this flag is set the drive will not
trip if the option module(s) or drive ratings are different between the
source and destination drives. The options module or rating dependent
parameters will not be transferred.
•

Setting 9666 in Pr

mm.000

will set the warning suppression flag

•

Setting 9555 in Pr

mm.000

will clear the warning suppression flag

9.3.9 9888 / 9777 - Setting and clearing the

SMARTCARD read only flag

The SMARTCARD may be protected from writing or erasing by setting
the read only flag. If an attempt is made to write or erase a data block
when the read only flag is set, a 'Card Read Only' trip is initiated. When
the read only flag is set only codes 6yyy or 9777 are effective.
•

Setting 9888 in Pr

mm.000

will set the read only flag

•

Setting 9777 in Pr

mm.000

will clear the read only flag

9.4 Data block header information

Each data block stored on a SMARTCARD has header information
detailing the following:
•

NV Media Card File Number

(11.037)

•

NV Media Card File Type

(11.038)

•

NV Media Card File Version

(11.039)

•

NV Media Card File Checksum

(11.040)

The header information for each data block which has been used can be
viewed in Pr

11.038

to Pr

11.040

by increasing or decreasing the data

block number set in Pr

11.037

If there is no data on the card Pr

11.037

can only have a value of 0.

9.5 NV Media Card parameters

Table 9-2 Key to parameter table coding

This parameter shows the number of the data block last transferred from
a SMARTCARD to the drive. If defaults are subsequently reloaded this
parameter is set to 0.

This parameter should have the data block number which the user would
like the information displayed in Pr

11.038

, Pr

11.039

and Pr

11.040

Displays the type/mode of the data block selected with Pr

11.037

Displays the version number of the file selected in Pr

11.037

Displays the checksum of the data block selected in Pr

11.037
