2.2
SOFTWARE INTERFACE
The following four protocols for communication between the remote
buffer and host computer are provided. The protocol meeting the
requirement of specifications of connection device can be selected by
setting a parameter.
Protocol Features of protocol
Interface
used
Transfer
rate (Max.)
RS-232-C 19200 BPSProtocol
A
It is the handshake system
where transmit/receive is
repeated between the both.
RS-422 86400 BPS
Expansion
protocol
A
It is nearly the same as the
protocol A. However, the NC
program can be transferred at
high-speed so that it can be
applied to the high-speed DNC
operation.
RS-422 86400 BPS
Protocol
B
It is the system for controlling
the communication between the
both by the control code output
from the remote buffer.
RS-232-C 19200 BPS
Expansion
protocol
B
The control system is the same
as that of protocol B. However,
it allows the transmission speed
to be increased. In this case, it
is required to receive the
reception synchronization clock
from the source.
RS-422 86400 BPS
NOTE
The average data transfer speed becomes smaller than
the maximum transfer speed.
