2.7 CF slot
A CFast Flash slot is located at the front, which enables the storage medium to be replaced. This allows the
storage medium to be exchanged. In the basic module this should only be done in switched­off state,
otherwise the system may crash. The CFast Flash card can be removed from the module for maintenance.
In this way it is also possible to expand the system (only operating system and program memory). CFast
Flash cards (CFast cards) are available as accessories in various sizes.
The following images illustrate the handling of the CFast cards. The eject mechanism is based on the push­
push principle: The CFast Flash card is disengaged with a soft click by lightly pressing the card. At the same
time the card moves approx. 4 mm out of the housing, so that it can be pulled out.
