9. CONNECTION TO FANUC I/O Link
209
Two channels of FANUC I/O Link interfaces are provided. Use of two
channels allows the number of usable I/Os to be increased to 2048 for both
inputs and outputs (previously, only 1024 inputs and 1024 outputs were
usable).
FANUC PMC Ladder Language Programming Manual (B–61863E) is
available separately to let you know how to use this feature, PMCs that
can take advantage of this feature, and the series and version of their
management software as well as the series and version of the CNC
management software.
NOTE
When this feature is to be used by the i Series CNCs
described above, PMC–SB6/SB7 needs to be specified.
The PMC on the loader control board cannot use this
feature.
Signals for two channels are assigned to the FANUC I/O Link connector
on the CNC. When using two channels, use the I/O Link branching
adapter to branch off the FANUC I/O Link.
