102 Function Description
WAGO-I/O-SYSTEM 750
750-880, 750-880/025-000 ETHERNET Programmable Fieldbus Controller
Manual
Version 1.0.1
Switch on the supply for the fieldbus controller.
In normal operation, the fieldbus controller starts.
The data from the /copy/ directory on the memory card is copied into the
appropriate directories on the internal file system.
Meanwhile, the SD-LED blinks yellow/orange.
The data is then loaded automatically and the settings automatically become
active.
Identical data that is already present in the internal file system is not copied. The
application runs with the copied data. Device settings and other files are saved on
the fieldbus controller and are executed.

Error message
Solution
No /copy/ and
/settings/ directories on
the memory card
System start of the
fieldbus controller is
running as if no
memory card were
present.
No message.
If memory card use is
desired, map the
directory structure of
the internal drive under
/copy/ on the memory
card on the PC.
Then restart the
fieldbus controller.
Manual interrupt
If the /copy/ directory
has not yet been copied
in full, then the copy
process is stopped on
manual interrupt. The

Blink code of the I/O
LED
(error code 14, error
argument 3) until the
error is eliminated.
Check internal file
system and /copy/
directory on the
memory card and
delete data if necessary
(e.g. via FTP,
formatting internal
drive or cleaning the
memory card on the
PC).
General internal error
The copy function is
cancelled. The data is
incomplete.
Blink code of the I/O
LED

The file size may not be larger than the size of the internal drive!
Note that the amount of data in the /copy/ directory may not exceed the total size
of the internal drive.
