successful Pr x.00 is simply set to 0. If the compare fails a trip is initiated and parameter 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 block.

Parameter file type data block

This type of data block is created when 3xxx in Pr x.00, the cloning 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 SMART card. 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. The data held in the data block has changed between different

software versions as follows:

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.

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 SMART card. 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 block is created by an application module, and contains user defined data.

When transferring data between drives the following should be noted:

Parameter transfer failure

When parameter or default difference data is transferred to the drive the parameters are automatically saved to drive EEPROM. If the transfer from

the card fails for any reason the drive produces the appropriate trip. If the failure occurs after the transfer has begun, it is possible that some, but not

all the parameters will have been updated with the card data. However, if the transfer fails the parameters are not saved to drive EEPROM, therefore

only the RAM values will be incorrect. If the drive is powered down and then powered up again the original drive parameters will be restored.
