2 SETTING THE DATA SERVER
FUNCTIONS
This chapter describes the communication setting for the Data Server
functions.
Notes on using the functions for the first time
CAUTION
1 When using the FAST Data Server for the first time, be sure to
initialize the memory card, set parameters, then turn the power off
then back on. If an attempt is made to use the Data Server functions
without following these steps, normal operation is not guaranteed.
2 Before performing FTP communication using the FAST Data Server
for the first time, consult with your network administrator, carefully
set a network address and other items, and conduct communication
tests thoroughly. Any error in settings such as a network address
setting can lead to an adverse influence such as a communication
failure on the entire network.
In particular, IP address duplication causes an intermittent
communication failure in the Data Server, which can result in a
system error in the CNC. So, be very careful when making settings.
3 When the power to the CNC is turned off during access to the
memory card, files stored on the memory card may be destroyed.
So, be careful not to turn off the power to the CNC during access to
the memory card.
4 In preparation for damage to the memory card, always take backup
copies of the files stored on the memory card to the host computer.
NOTE
1 With the Data Server functions (FTP client), a single CNC can
connect only one FTP server.
2 With the Data Server functions (FTP server), a single CNC can
connect up to five FTP clients. However, some FTP client software
programs may each internally use two or more FTP clients. Note,
therefore, that the number of FTP clients is not always equal to the
number of applications.
3 The Data Server functions do not support passive mode (PASV
command).
