In FANUC I/O Link (omit as I/O Link) there are the master station and
its slave stations. The master is the Controller of the Power Mate or
others, and the slaves are the I/O unit and I/O card. Power Mate can be
used as slave. The slaves are divided into groups, and up to 16 groups can
be connected to one I/O Link. A maximum of two base I/O units can be
connected as a group. The I/O card and FANUC SERVO AMPLIFIER
β series (I/O Link Option) are each counted as one group.
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 JD1B
of the last unit is not used and left open, it need not be connected with a
terminator. Power Mate uses JD1A1 to connect I/O card etc... as a master,
and uses JD1A and JD1B to be slave controller of other CNC controller.
The pin assignments of connectors JD1A and JD1B are common to all
units on the I/O Link, and are illustrated on the next page. Use the figures
when connecting the I/O Link irrespective of the type of unit.
