9. CONNECTION TO FANUC I/O Link
331
The maximum number of β amplifiers with I/O Link that can be
connected to a control unit depends on the maximum number of FANUC
I/O Link points provided by that control unit, as well as their assignments.
For the i Series, the maximum number of FANUC I/O Link DI and DO
points are 1024 and 1024, respectively. One β amplifier with I/O Link
occupies 128 DI/DO points in the FANUC I/O Link. If no units other than
the β amplifiers with I/O Link are connected to the control unit, up to eight
β amplifiers can be connected.
If the β amplifier with I/O Link is used as an I/O Link slave, I/O addresses
are assigned in the PMC in the CNC. Because data output from the slave
is made in 16–byte units, the number of input/output points must be set
to 128.
The module names are OC02I (input) and OC02O (output).
The BASE is always 0, and the SLOT is 1.
