1.2.4 Installing a Memory Card
The following shows the specifications of memory cards
recommended as an external storage device of the FAST Data Server.
Specification Capacity Remarks
A02B-0281-K601 128MB CompactFlash card
A02B-0213-K211 256MB CompactFlash card
A02B-0213-K212 1GB CompactFlash card
Generally, because of characteristics of the internal flash memory,
repeatedly reading data from a CompactFlash card can degrade
internal data and result in a data error.
Even if such a problem arises, the CompactFlash cards listed above
have a function for restoring data automatically, so incorrect data will
not be read from these cards. However, a read operation may take a
time temporarily.
The delay in read time is related to memory operation performance
(speed) and finish on machined surfaces. So, this should be taken into
consideration when these cards are used.
For memory operation, these cards should be used with the processing
time per block set to 24 ms or longer.
For DNC operation, a sufficient buffer is provided between the Data
Server and the CNC, so there is no influence on machining even if the
delay mentioned above is generated in read operation.
Operation checks have been conducted for SanDisk's adapter
(SDAD-38-J60) that converts the above CompactFlash cards to an
ATA card.
