8. CONNECTION TO FANUC I/O Link
99
For the Series 0i–C and Series 0i Mate–C, the interface connector for I/O
Link (JD1A) is located on the unit main board.
In the I/O Link there are the master station and its slave stations. As the
Series 0i/0i Mate control unit, the master is connected to slaves such as
a distributed I/O slave. The slaves are divided into groups, and up to 16
groups can be connected to one I/O Link. (For the Series 0i Mate,
however, the number of I/O points is restricted.)
The I/O Link is connected in different ways depending on the types of
units actually used and the I/O points. To connect the I/O Link, the
assignment and addresses of the I/O signals have been made
programmable with the PMC program. The maximum number of I/O
points is 1024.
The two connectors of the I/O Link are named JD1A and JD1B, and are
common to all units (that have I/O Link function). A cable is always
connected from JD1A of a unit to JD1B of the next unit. Although JD1A
of the last unit is not used and left open, it need not be connected with a
terminator.
The pin assignments of connectors JD1A and JD1B are common to all
units on the I/O Link, and are illustrated on Subsec. 8.2.1. Use the figures
when connecting the I/O Link irrespective of the type of unit.
