Key Titles can be Marked on the Function
Key Sheet

Key titles can be marked on the function key sheet in
accordance with the applications of the keys: the sheet can
be taken out from the side face of the terminal.
The front panel of the terminal has a water-withstanding
construction.

Example key titles:

F1
RUNF2 AUTF3 MAN.

F4
STOP

Long-lived Backlight

Since LEDs are used for the backlight, it is very long-lived
and rarely needs to be changed.

Display History Record Helps in Analysis of
Machine Faults

When the display history record function is set as a screen
attribute, the time, the screen number, and a comment are
recorded in the terminal's memory every time the relevant
screen is displayed. This display history can be printed by
issuing a print instruction from the host, and is useful for
machine fault analysis.
