Furthermore, the user has some operation options in the storing files area, which are the following:
ï‚· New directory : allows the creation of a new folder in the user memory area
ï‚· Delete item : allows the files excluding in the folders in the user memory area
ï‚· Refresh : allows the file updating, on the MasterTool IEC XE screen, of the files in the user
memory area and in the computer
Figure 4-88. Utilization Options
ATTENTION:
For a CPU in Stop Mode or with no application, the transfer rate to the internal memory is
approximately 150 Kbytes/s.
Memory Card
Among other memories, the NX3010, NX3020 and NX3030 Nexto Series CPUs allow the user the
utilization of a memory card. It is defined according the features described in
Memory Card Interface chapter which stores, among other files, the project and application in the
CPU internal memory.
When the card is inserted in the CPU and it presents a file type different from FAT32, it
automatically identifies those files and questions the user if he wants to format the files. In negative
case the user cannot use the card, as it is not mounted. A message informing the format is not
recognized is presented and the card presence is not displayed either. 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
its general information, leaving access to the slower memory card in the first few minutes. This
procedure is done only when the card is inserted or in case of the CPU reset.
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 the MasterTool IEC XE software, the user enables the CPU
project copy option for the memory card or the project copy from the card to the CPU. On this same
