6. CONNECTION OF I/O UNITS TO
MACHINE INTERFACE
121
The Series 15–B can be combined with the units shown in the table below
as I/O units for the machine interface.
The I/O units for the FANUC I/O Link are installed separately from the
control unit, and connected with the control unit using the dedicated serial
FANUC I/O Link.
As shown in the figure below, two or more units can be installed
separately. By placing the connection unit for the operator’s panel near
the operator’s panel, an operator’s panel that inputs/outputs many signals
can be interfaced easily.
The FANUC I/O Unit–MODEL A is a modular–type I/O unit. It selects
necessary modules from various I/O modules provided by FANUC
according to the application and uses them as one external unit. The
FANUC I/O Link transfers data between the control unit and such an
external unit at a high speed. The states of the input signals from the
machine are transferred to the control unit at regular intervals. The states
of the output signals from the control unit are transferred to external units
at regular intervals. (Note that this manual covers only part of the uses
that the FANUC I/O Link has. For example, although it can be used for
connecting the 1–axis CNC FANUC Power Mate or cell controller
FANUC F–D Mate, this manual does not mention it. This is because the
purpose of this manual is to describe the I/O units having machine
interface.)
