G SD Card Functionality
The recommended procedure to back up a configuration is to use the backup function in
Studio 5000. It is NOT recommended to use the SD card for backups.
The SD card acts as client in the linking device. When a device is turned on with an SD
card inserted, and that SD card contains a valid configuration file, the configuration on
the SD card will always overwrite any configuration on the linking device. This may result
in a checksum missmatch, and the Linking Device will reject any connection attempts
from the PLC.
G.1 General Guidelines
Turn the power off before inserting or removing an SD card from the linking device.
Do not turn the linking device off while the SD LED indicates that the SD card is being accessed.
The linking device will not write any data to a write-protected SD card.
G.2 Starting Up
1. Format the SD card for the FAT file system using a PC. The linking device cannot use an
unformatted SD card.
2. Make sure the SD card is empty and that it is not write-protected.
3. Turn the linking device off.
4. Insert the SD card into the SD card slot in the linking device.
5. Turn the linking device on.
6. Create the configuration. When finished, press the apply button in the Management section
to reboot using the new configuration. During the reboot, the latest applied configuration
will automatically be copied and saved to the SD card.
7. Now, the SD card is synchronized with the linking device. Both the SD card and the linking
device contain the latest applied configuration.
Every time a new configuration is applied in the Management section, it is also copied to the SD
card to ensure synchronization.
G.3 Easy Backup
Every time a configuration change is applied in the Management section using the configuration
web pages, the configuration is saved to Studio 5000 and the Logix PLC memory, as well as to the
linking device and the SD card. This is the easiest way of keeping a continuously updated
configuration backup.
G.4 Simple Configuration Copy
If a configuration on one linking device needs to be copied to one or more other linking devices,
it is easily done using an SD card.
1. Turn the linking device running the desired configuration off.
