I/O CHANNEL: Selection of an input/output device or selection of input device in
the foreground
This parameter can be entered on the setting screen
[Data type] Byte
[Valid data range] 0 to 35
I/O CHANNEL: Selection of the input/output device to be used
The CNC provides the following interfaces for data transfer to and from
the host computer and external input/output devices:
D Input/output device interface (RS–232C serial port 1, 2)
D DNC2 interface
Data input/output is possible with a PC connected via the
FOCAS1/Ethernet or FOCAS1/HSSB interface.
In addition, data can be transferred to and from the Power Mate via the
FANUC I/O Link.
This parameter selects the interface used to transfer data to and from an
input/output device.
Setting Description
0, 1 RS–232C serial port 1
2 RS–232C serial port 2
5 Data server interface
6 The DNC operation is performed or M198 is specified by FOCAS1/
Ethernet.
10 DNC2 interface, OSI–Ethernet
15 M198 is specified by FOCAS1/HSSB. (Bit 1 (NWD) of parameter
No. 8706) must also be specified.)

Data is transferred between the CNC and a Power
Mate in group n (n: 0 to 15) via the FANUC I/O Link.
Supplemental remark 1
If the DNC operation is performed with FOCAS1/HSSB, the setting
of parameter No. 20 does not matter. The DMMC signal <G042.7>
is used.
Supplemental remark 2
If bit 0 (IO4) of parameter No. 110 is set to control the I/O channels
separately, the I/O channels can be divided into four types: input and
output in the foreground and input and output in the background. If
so, parameter No. 20 becomes a parameter for selecting the input
device in the foreground.
