(Note) SLC stands for Single Level Cell, and it stores one bit data in each memory cell.
This provides longer life span and high product reliability in comparison with MLC (Multi Level Cell), which is
commonly applied to CF cards.
2.11.1 Precautions for Use of Commercially Available CF Cards
Mitsubishi is unable to guarantee the machine operation when a commercially available CF card or SD memory card
(SD-CF adapter is required) is used. In that case, performance check must be made carefully by machine tool builder.
(1) Commercially available CF cards may not be compatible with MITSUBISHI units or suitable FA environment for
temperature- or noise-wise. In case of using it, careful performance check must be required by the machine tool
builder.
(2) When inserting/removing a commercially available CF card, turn the MITSUBISHI device’s power OFF to avoid any
troubles. If a card must be inserted and removed while the power is ON, make sure to take sufficient time (approx.
ten seconds or more) between the insertion and removal.
(3) Do not pull out the card or turn OFF the power during access to the CF card. Failure to observe this could cause the
memory contents to be erased. In case of emergency, always perform backups by having your important data
duplicated, etc. as MITSUBISHI will not guarantee the broken or lost data.
