S Numeric Key (System Key) Function
With the numeric keys (system keys) assigned to the input terminals, the input
terminals can function similar to those keys specified. However, with the sys-
tem keys assigned to the input terminals, those terminals cannot be used as
the system keys other than the operation mode (system menu, etc.).
The following numeric keys (system keys) can be assigned to the input termi-
nals.

When a screen switchover key for each screen is also assigned to the same in-
put terminal, it acts as the screen switchover key.
S Stand Alone Function
With the screen number assigned to the input terminal, it can function as the
screen switchover key similar to the touch switch. However, with 0 specified to
the screen number, it functions as the screen switchover return key (see page
157).
Other than setting the input terminal as the screen switchover key that acts at
each screen similar to the touch switch, it can also be set as the screen switch-
over key common to all screens. However, when the screen number common
to all screens and the screen number for each screen are assigned concurrent-
ly to one input terminal, the screen number for each screen have priority.
With the Windows version of the NT-series Support Tool, setting for each screen
is not possible. The terminal will always be used as the switchover key for all
screens.
S External Output Function
With the PC bits assigned to the output terminals, those output terminals can
be turned ON/OFF in accordance with the state of the bits to which the output
terminals are specified. External equipment connected to the output terminals
can be controlled by the PC.
ON/OFF state of the output terminal is held unless the state of the bit is
changed.
