B-61813E/03 CONNECTIONS 4. CONNECTION
1 Set the terminating resistor DIP switch to ON.
2 Set the terminating resistor DIP switch to OFF.
(2) Connection with the I/O link
The AIF02C occupies two groups on the I/O link.
When groups #n and #n+1 are used, for example, the smaller-
numbered group, #n, is assigned to the I/O Unit-A, and the
larger-numbered group, #n+1, is assigned to the I/O Unit-B.
[a] Connection of the I/O link cable
Connect the I/O link cable from the previous group to JD1B.
Connect JD1A to the I/O link cable leading to the next group.
Use the K1X I/O link signal cable, the same I/O link signal
cable type as that for the AIF01A.
[b] Number of occupied I/O points on the I/O link
The nominal number of occupied I/O points may differ from
the actual number of I/O points. For the details of the
number of I/O points occupied by the I/O Unit-B, refer to
Section 4.2.1, "Number of points occupied on the interface
unit I/O link," of the FANUC I/O Unit-B MODEL
Connection Manual (B-62163E).
(3) Connection with the distributed link (I/O Unit-B)
[a] Number of distributed communication lines (I/O Unit-B)
"T1" can connect to two communication lines (twisted-pair
So, it is possible to branch to up to two lines.
To branch to more lines, you should use the I/O Unit-B
interface unit (BIF04A1), which enables branching to up to
eight communication lines.
[b] Terminal board "T1," used for connection with the
distributed link cable
The distributed link cable is connected to "T1."
Q Use twisted-pair wires as the distributed link cable.
R The distributed link cable is polarity-sensitive. Match
the signal polarity of the AIF02C with that of the basic
S The terminal board has M3 screws with a terminal
