Keystroke log
The control stores each key pressed and important events (e.g.,
system start) in a keystroke log. The capacity of the keystroke log
is limited. When the keystroke log is full, the control switches to
a second keystroke log. When this is also full, the first keystroke
log is deleted and newly written, etc. If required, switch from
CURRENT FILE to PREVIOUS FILE to view the history of the inputs.
Press the LOG FILES soft key
Open the keystroke log file: Press the
KEYSTROKE LOG soft key
Set the previous keystroke log if required: Press
the PREVIOUS FILE soft key
Set the current keystroke log if required: Press the
CURRENT FILE soft key
The control saves each key pressed during operation in a keystroke
log. The oldest entry is at the beginning, and the most recent entry is
at the end of the file.

Informational texts
If an operating error occurred, e.g. pressing an impermissible key or
entering a value outside of a validity range, the control displays an
information text in the header to inform you of the operating error.
The control deletes this information text with the next valid entry.
