FTP mode
In the FTP mode, data is transferred between the host computer built-in
hard disk and CNC part program storage.
For example, DNC operations including a DNC operation by a
subprogram call (M198) require that the related NC programs be stored
on the host computer (personal computer) built-in hard disk. If an NC
program is output, it will be stored on that hard disk.
CAUTION
1 In FTP mode, CNC data is transferred from the host
computer hard disk to the CNC part program storage
memory. So, if the line is disconnected during
communication due to network noise or any other
reason, the line disconnection has a direct effect on
CNC operations with compared to the storage mode.
2 If communication between the CNC and host
computer is interrupted, for example, by putting the
CNC on feed hold during a DNC operation in the FTP
mode, the host computer may disconnect the
communication. Perform trial run to put the CNC on
feed hold and make sure that communication with the
host computer is not interrupted.
