The data, and the format of the data, is different depending on the method used to store it on a SMARTCARD. The different formats are described
below. In addition to data transfers a compare function is provided.
If 8yyy is entered in Pr x.00 and the drive is reset data block yyy on the SMARTCARD is compared with the data in the drive. If the compare is
successful Pr x.00 is simply set to 0. If the compare fails a trip is initiated and Pr x.00 is not cleared. This function can be used with all data block
types except the option type (18) and Opt.Prg (19) type of data blocks.
Parameter file type data block
This type of data block is created when 3xxx in Pr x.00, the copying parameter (Pr 11.42) or auto/boot mode is used to initiate the transfer. The data
block (referred to as a parameter file) contains the complete data from all user save (US) parameters except those with the NC coding bit set.
Parameter RAM is used as the source of this information. Power-down save (PS) are not saved to the SMARTCARD. When the data is transferred
back to a drive, it is transferred to the drive RAM and then the drive EEPROM. A parameter save is not required to retain the data after power-down.
Before the data is taken from the card, defaults are loaded in the destination drive using the same default code as was last used in the source drive.
Difference from defaults type data block
This type of data block is created when 4xxx in Pr x.00 is used to initiate the transfer. This data block format (referred to a difference from defaults file)
transfer parameters with the following attributes: NC=0 (clonable) and US=1 (user save), and menu 20 parameters except Pr 20.00 if they are
different from their default value. If a parameter is user save (US), but has no default (ND) it is saved on the card whatever its value.
It is possible to transfer parameters between drives with each of the software version dependant formats, however, the data block compare function
does not work with data produced by the different formats.
The data density is not as high as a parameter file type data block, but in most cases the number of differences from default is small and the data
blocks are therefore smaller. This method can be used, for example, for creating drive macros. Parameter RAM is used as the source of this
information.
When the data is transferred back to a drive, using 6yyy in Pr x.00, it is transferred to the drive RAM and then to the drive EEPROM. A parameter
save is not required to retain the data after power-down.
Onboard Application Lite user program data blocks
This type of data block is created when 5xxx in Pr x.00 is used to initiate the transfer. The Onboard Application Lite user program from a drive may be
transferred to/from internal flash memory from/to a SMARTCARD. If the user program is transferred from a drive with no program loaded the block is
still created on the card, but contains no data. If this is then transferred to a drive the drive will then have no user program.
Option type data block
This type of data block is created by an applications module and contains user defined data.
Code Action
Pr x.00 = 2001
Transfer drive parameters as difference from defaults to a bootable SMARTCARD block with
block number 1. (This will clear data block 1 on the card if it already exists.)
Pr x.00 = 3yyy Transfer drive parameters to a SMARTCARD block number yyy as a parameter file
Pr x.00= 4yyy Transfer drive data to a SMARTCARD block number yyy as difference from defaults file
Pr x.00 = 5yyy Transfer drive user program to SMARTCARD block number yyy
Pr x.00 = 6yyy Transfer SMARTCARD data block yyy to the drive
Pr
x.00 = 7yyy Erase SMARTCARD data block yyy
Pr x.00 = 8yyy Compare drive parameters with block yyy
Pr x.00= 9555 Clear SMARTCARD warning suppression flag
Pr x.00 = 9666 Set SMARTCARD warning suppression flag
Pr x.00 = 9777 Clear SMARTCARD read-only flag
Pr x.00 = 9888 Set SMARTCARD read-only flag
Pr x.00= 9999 Erase SMARTCARD
Pr x.00 = 15yyy
Transfer the user program in the applications module in slot 1 to data block number yyy on a
SMARTCARD
Pr x.00 = 16yyy
Transfer the user program in the applications module in slot 2 to data block number yyy on a
SMARTCARD
Pr x.00 = 17yyy
Transfer the user program in the applications module in slot 3 to data block number yyy on a
SMARTCARD
Pr x.00 = 18yyy
Transfer a user program in data block number yyy on a SMARTCARD to the applications module
in slot 1
Pr x.00 = 19yyy
Transfer a user program in data block number yyy on a SMARTCARD to the applications module
in slot 2
Pr x.00 = 20yyy
Transfer a user program in data block number yyy on a SMARTCARD to the applications module
in slot 3
Pr 11.42 = Read Transfer SMARTCARD data block 1 to the drive provided it is a parameter file
Pr 11.42 = Prog Transfer drive parameters to a SMARTCARD block number one as a parameter file
Pr 11.42 = Auto
Pr 11.42 = boot
Transfer drive parameters to a SMARTCARD block with data block number 1 as a parameter file
provided Pr 11.42 has been changed since power-up.
