Data is transferred between the CNC and a Power
Mate CNC 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.
NOTE
1 An input/output device can also be selected using the setting screen. Usually, the setting screen
is used.
2 The specifications (such as the baud rate and the number of stop bits) of the input/output
devices to be connected must be set in the corresponding parameters for each interface
beforehand. (See Section 4.2.) I/O CHANNEL = 0 and I/O CHANNEL = 1 represent input/output
devices connected to RS–232C serial port 1. Separate parameters for the baud rate, stop bits,
and other specifications are provided for each channel.
3 The input/output unit interface may be referred to as the reader/punch interface.
RS–232C serial port 1 and RS–232C serial port 2 are also referred to as channel 1 and channel
2, respectively. The remote buffer interface is also referred to as channel 3.
4 JD36A, JD36B, JD28A, and JD6A represent the connector numbers on the printed–circuit board.
