5. 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 OWFF signels can be received by usbq buffer memory, which is explained later in this
Manual.

6. BUFFER MEMORY (BFM) ASSEWEMT-
The f?X-16NP/NT-S3 interface block uses its built-inbuffer memory (%-word RAM without battery
back@) for communications withthe A series PC. The buffer memory is assigned,with the numbers
as shown below.
