6. CONNECTION OF I/O UNITS TO
MACHINE INTERFACE
B–63783EN/01

Combinations of the units listed in Table 6.1 can be used as the machine
interface I/O.
The I/O unit for the FANUC I/O Link is installed separately from the
control unit, and the two units are mutually connected by a specialized
serial link (FANUC I/O Link). Multiple units can be placed in separate
locations as shown below. The machine operator’s panel that uses many
input/output signals can be easily interfaced especially by placing the
interface unit for machine operator’s panel and the operator’s panel
connection unit in the immediate vicinity of the machine operator’s panel.
The FANUC I/O Link enables high–speed data transfer between the
control unit and an external unit. The statuses of signals input from the
machine are transferred to the control unit at constant intervals. The
output signals from the control unit are sent to the external unit at constant
intervals. The FANUC I/O Link has more applications. For example, the
FANUC I/O Link is used to connect the FANUC Power Mate, which is
single–axis CNC, or the FANUC System F–Model D Mate (F–D Mate),
which is a cell controller. For details, see the subsequent description.
For details of the units which are not listed in Table 6.1, see the
corresponding operating manual.
