ATTENTION:
For a CPU in Stop Mode or no application, the transfer rate to internal memory is approximately 150
Kbytes/s.
Memory Card
Among other memories, the Hadron Xtorm Series CPUs allow the user the utilization of a memory
card. It is defined according the features described in Technical Description, which stores, amongst
other files, the project and the CPU internal memory application.
When the card is inserted in the CPU and it features a file system different than FAT32, it
automatically identifies those files and prompts the user about formatting the files. In negative case
the user cannot use the card, as it will not mount. The CPU displays a message informing a mismatch
format, so the display card does not indicate the card. If the user decides to format the files, the CPU
takes a few minutes to execute the operation, depending on the cycle time (execution) of the
application which is running in the CPU. Once the memory card is mounted, the CPU will read
general information from it, leaving the memory card access slower in the first few minutes. This is
done only when the memory card is inserted or when the CPU is restarted.
ATTENTION:
It is recommended to format the memory card directly in the Nexto CPU in order to avoid possible
use problems, mounting time increase or even the incorrect functioning. It is not recommended to
remove the memory card or de-energize the CPU during the formatting or during the files transfer as
it can cause the loss of data as well as irreversible damages.
During the project configuration in MasterTool IEC XE software, the user enables the option for
copy the CPU project to the memory card. On this same screen the user can set the access passwords
so as to control the use of such information. For further information, see section CPU Configuration -
Memory Card.
