Data Server
CNC memory

DNC operation
Punch
Host computer
CAUTION
1 In the FTP mode, an NC program is transferred
from the host computer to the CNC. For this
reason, if the line is disconnected during
communication for some reason such as noise on
the network, the disconnection directly affects the
CNC operation as compared with the storage
mode. Before DNC operation in the FTP mode,
surely take measures to prevent noise and make
sure that good communication conditions are
present.
2 When feed hold is performed during DNC
operation in the FTP mode, communication with
the host computer may be stopped. In this case,
the host computer may disconnect the
communication. Perform feed hold during a trial
run and completely confirm that the communication
with the host computer is not disconnected.
Buffer mode
The host computer connected to the Data Server is selected as the
external input device.
In the buffer mode unlike the FTP mode, however, areas on the
memory card built into the Data Server are used as intermediate
buffers. For details of the buffer mode, see Section 2.3, "DETAILS
OF THE BUFFER MODE," which is the following section.
As the external output device, the memory card built into the Data
Server is selected. When NC program output operation (punch) is
performed, the operation equivalent to that in the storage mode is
performed.
