Memory Card Function
Only use recommended memory cards!
Use only the microSD memory card available from WAGO (item No. 758-
879/000-3102) as it is suitable for industrial applications subjected to
environmental extremes and for use in this device.
Compatibility with other commercially available storage media cannot be
guaranteed.
The memory card is optional and serves as an additional memory area in
addition to the internal memory or drive in the controller. The user program, user
data, source code of the project or device settings can be saved to the memory
card, and thus already existing project data and programs can be copied to one
or more controllers.
If the memory card is inserted, this is incorporated under /media/sd in the
directory structure of the file system inside the controller. This means that the
memory card can be addressed like a removable medium on a PC.
The function of the memory card in normal operation and possible faults that may
occur when the memory card is used are described in the following sections for
different operating modes.
4.2.1
Formatting
Note the pre-formatting of the memory card!
Please note that memory cards ≤ 2 GB are often formatted with the “FAT16” file
system type and can generate up to 512 entries in the root directory. For over
512 entries create these in a subdirectory or format the memory card with
“FAT32” or “NTFS.”
Memory card access from CODESYS only possible with FAT16, FAT32 or
NTFS!
If the CODESYS user “admin” (see the section “Network” > “Network Security” >
“Users and Passwords” > “Services and Users“) is supposed to be able to access
files created on the memory card, the memory card must be formatted with
FAT16, FAT32 or NTFS.
If the Linux
®
file system formats EXT2 or EXT3
are used, “root” rights are
required for data access. Therefore, access via CODESYS is not possible.
