6. CONNECTION OF I/O UNITS TO
MACHINE INTERFACE
53
Combinations of the units listed in Table 6.1 can be used as the machine
interface I/O.
The I/O units can be classified into two types: the I/O units tailored to the
FANUC I/O Link, and the built-in I/O unit. 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 Fig. 6.2.1.
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.
For details of the units which are not listed in Table 6.1, see the
corresponding operating manual.
The built–in I/O unit is installed in the control unit.
The Power Mate supports the simultaneous use of the built–in I/O unit and
I/O units tailored to the FANUC I/O Link.
An I/O unit for FSSB is mounted on the FSSB line connected to a servo
amplifier. It is, therefore, useful if the Power Mate i is remote from the
servo amplifier cabinet.
