Information information Installation
9.3.7 7yyy / 9999 - Erasing data from the
SMARTCARD
Data can be erased from the SMARTCARD one data block at a time or
with data blocks 1 to 499 in selected together.
• Setting 7yyy in Pr xx.00 will erase SMARTCARD data block yyy
• Setting 9999 in Pr xx.00 will erase SMARTCARD data blocks 1 to
499
9.3.8 9666 / 9555 - Set / clear SMARTCARD warning
suppression flag
1. If the Solutions Module(s) installed to the source and destination
drive are different, or are in different slots, the drive will produce a
'C.Optn' trip.
2. If the data is being transferred to a drive of a different voltage or
current rating a 'C.rtg' 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 Solutions Module(s) or
drive ratings are different between the source and the destination drives.
The Solutions Module or rating dependent parameters will not be
transferred.
• Setting 9666 in Pr xx.00 will set the warning suppression flag
• Setting 9555 in Pr xx.00 will clear the warning suppression flag
9.3.9 9888 / 9777 - Set / clear 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 'C.rdo' trip is initiated.
When the read only flag is set only codes 6yyy or 9777 are effective.
• Setting 9888 in Pr xx.00 will set the read only flag
• Setting 9777 in Pr xx.00 will clear the read only flag

Data block header information

Each data block stored on a SMARTCARD has header information
detailing the following:
• A number which identifies the data block (Pr 11.37)
• Type of data stored in the data block (Pr 11.38)
• Drive mode if the data is parameter data (Pr 11.38)
• Version number (Pr 11.39)
• Checksum (Pr 11.40)
• Read-only flag
• Warning suppression flag
The header information for each data block that has been used can be
viewed in Pr 11.38 to Pr 11.40 by increasing or decreasing the data block
number set in Pr 11.37.
If Pr 11.37 is set to 1000: the checksum parameter (Pr 11.40) shows the
number of bytes left on the card in 16 byte pages.
If Pr 11.37 is set to 1001: the checksum parameter (Pr 11.40) shows the
total capacity of the card in 16 byte pages. Therefore, for a 4kB card this
parameter would show 254.
If Pr 11.37 is set to 1002: the checksum parameter (Pr 11.40) shows the
state of the read-only (bit 0) and warning suppression flags (bit 1).
If there is no data on the card: Pr 11.37 can only have values of 0 or
1000 to 1002.
