5. CONFIGURATION
Figure 135: 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.
5.10. Memory Card
Among other memories, Nexto Series CPUs allow the user the utilization of a memory card. It is defined according the
features described in Memory Card Interface section 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 memory card slower 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 for-
matting or during the files transfer as it can cause the loss of data as well as irreversible
damages.
5.10.1. Project Preparation
To use the functionality, during the project configuration, in the MasterTool IEC XE software, the user must enable the
option to copy the CPU project to the memory card and/or memory card to the CPU and to configure passwords. These
passwords will be requested by the CPU when executing the respective transfer. For information about the table, see section
Project Parameters.
ATTENTION
If the CPU has no application, the “Memory Card” Menu will be available to allow the
transfer of the project from memory card to the CPU without requiring any kind of previous
preparation of the CPU.
To use the feature you must perform the following steps.
