I/O
DATA
ASSIGNMENT
Eight
points
of
ON/OFF
signals for-bothinput and
output are transmitted and
received between an
FX-
16NP/NT-S3 and
the
A
se-
ries master
PC.
These
signals on an
FX
series
lo-
cal PC are mapped as in-
put and output relays in
the table shown on the
right.
More than one interface
block can be connected
to
one
FX
series PC. The
FX-16NP/NT-S3 can be
lo-
cated at any desired posi-
tion.
More

can be
received
by
