4.2 PARAMETERS OF READER/PUNCHER INTERFACE,
REMOTE BUFFER, DNC1, DNC2, AND M-NET INTERFACE
Before data (programs, parameters, and so on) can be input from and
output to an external input/output device via the input/output device
interface (RS-232-C serial port), the parameters explained below must
be set.
In the I/O CHANNEL setting parameter, the input/output device to be
used is selected by specifying one of the two channels (RS-232-C
serial port 1 and RS-232-C serial port 2) that is connected to the
input/output device.
In addition, the specifications of an input/output device connected to
each channel (such as the specification number, baud rate, and number
of stop bits of the input/output device) must be set in parameters
corresponding to each channel in advance.
For channel 1, two combinations of parameters to specify the
input/output device data are provided.
The following shows the interrelation between the input/output device
interface parameters for the channels.
