FTP Network Access to the File System of the Memory
Card
The fieldbus node is in operation and the memory card is plugged in.
The FTP client accesses the file system of the memory card (drive

network.
In normal operation, the FTP client writes data to the file system of the memory
card or reads data from the file system of the memory card.
Meanwhile, the SD-LED blinks yellow/orange.
The data is then written or read.
