Update rate Background
Data blocks are stored on a SMARTCARD with header information which includes a number which identifies the block. The header information also
includes the type of data stored in the block, the drive mode if the data is parameter data, the version number and a checksum. This data can be
viewed through Pr 11.38 to Pr 11.40 by increasing or decreasing Pr 11.37. This parameter jumps between the data numbers of the data blocks
present on the card inserted into the drive. If this parameter is set to 1000 the checksum parameter shows the number of bytes left on the card. If
there is no data on the card Pr 11.37 can only have values of 0 or 1000.
The actions of erasing a card, erasing a file, changing a menu 0 parameter, or inserting a new card will effectively set Pr 11.37 to 0 or the lowest data
block number in the card.
Data transfer and erasing can be performed by entering a code in Pr x.00 and then resetting the drive as shown in the table below.
Code
3yyy Transfer drive EEPROM data to a SMARTCARD block number yyy
4yyy Transfer drive data as difference from defaults to SMARTCARD block number yyy
5yyy Transfer drive ladder program to SMARTCARD block number yyy
6yyy Transfer SMARTCARD data block yyy to the drive
7yyy Erase SMARTCARD data block yyy
8yyy Compare drive parameters with block yyy
9999 Erase SMARTCARD
9888 Set SMARTCARD read-only flag
9777 Clear SMARTCARD read-only flag
Data blocks with numbers from 1 to 499 can be created or erased by the user. Data block with numbers 500 and above are read only and cannot be
created or erased by the user. The whole card may be protected from writing or erasing by setting the read-only flag (i.e if the flag is set then only
codes 6yyy or 9777 are effective).
If the destination drive has a different drive mode to the parameters on the card, the drive mode will be changed by the action of transferring
parameters from the card to the drive.
After an attempt to read, write or erase a trip may occur, see Pr 10.20 on page 148 for details. If the card is removed during data transfer from the card
for a data block that was saved with code 3yyy, the drive EEPROM checksum will be set up to be incorrect and an EEF trip will be initiated. If the card
is removed during data transfer from the card for a data block that was saved with code 4yyy then no data will be saved to EEPROM and a C.Acc trip
will be initiated. It should be noted that in both cases the parameters held in drive parameter RAM are likely to be incorrect.
During SMARTCARD or EEPROM data transfer the user will not be able to exit keypad edit mode when the current parameter is in menu 0.
Parameter data block when 3yyy is used to transfer data to a card
The data blocks contain the complete data from the drive EEPROM, i.e. all user save (US) except the parameters with the NC coding bit set. Power-
down save (PS) are not saved to the SMARTCARD. A SMARTCARD can hold up to 4 data blocks of this type.
When the data is transferred back to a drive, using 6yyy in Pr x.00, it is transferred to the drive RAM and drive EEPROM. A parameter save is not
required to retain the data after power-down. (When parameters are copied to the drive RAM this action is performed twice to prevent interdependent
parameters from being copied incorrectly.) 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.
The categories of modules fitted to the card data source drive are stored on the card. If these are different from the destination drive, the menus for
the slots where the Solutions Module categories are different, are not modified and so they will contain their default values, and the drive will produce
a C.Optn trip. If the data is transferred to a drive of a different voltage, or current rating from the source drive, all parameters with the RA coding bit set
(as given in the table below) are not modified and a C.rtg trip occurs.
