6.2.5 CFast card installation and removal
NOTE
Loss of data
CFast cards are subjected to heavy load during operation and have to withstand many write cycles and ex-
treme ambient conditions. CFast cards from other manufacturer may fail, resulting in data loss.
• Only use industrial CFast cards provided by Beckhoff.
A CFast card is a non-volatile memory. Data to be retained in the event of a power failure should be saved
on the CFast card. The CFast cards supplied by Beckhoff are industrial cards with an increased number of
write cycles and an extended temperature range (+85 °C).
The eject mechanism is based on the push/push principle. The installation and removal of CFast cards is
described below.
Requirements:
• The basic CPU module must be switched off. The CFast cards may only be installed or removed in
switched off state.
Removing a CFast card
1. Gently push the CFast card.
A soft click can be heard when the card is released.
2. The card is lifted by approx. 4 mm from the housing. Pull out the card.
Installing a CFast card
1. Push the CFast card into the CFast card slot.
2. A soft click can be heard when the CFast card engages.
ð
The card is seated correctly if it is flush with the front side of the device housing.
