B.3 SETTING THE DATA SERVER FOR Series 16i/18i/21i-A/B
AND Series 0i-B/C
This section describes the setting required to operate the Data Server
function for Series 16i/18i/21i-A/B and Series 0i-B/C (including the
FTP server function).
When using the FTP server function of the Data Server, see Subsections
B.3.1 and B.3.2.
When an FTP server is to be set on a PC and the setting information is to
be set as parameters for the Data Server (to use the Data Server
function), see Subsections B.3.1 and B.3.3.
B.3.1 Precautions to be Observed when Using the Data Server
Functions for the First Time
CAUTION
1 When the Data Server board or FAST Data Server is used for the first
time, format the hard disk or ATA card, set the appropriate parameters,
and turn the power off then on again. If the Data Server functions are
used without performing these operations, normal operation cannot be
guaranteed.
2 When Ethernet FTP communication is performed for the first time,
consult with your company's network administrator to determine the IP
addresses and other settings. Then, conduct a communications test.
If incorrect IP addresses and other settings are set, communications
may be interfered with or the entire network might be adversely
affected.
Particularly, if a duplicate IP address is set, communication errors are
caused intermittently. This may result in a CNC's system error.
3 Never turn off the power to the CNC while the hard disk or ATA card
(hereinafter simply referred to as the hard disk) is being accessed
(while a Data Server function service is being executed). Otherwise,
the data on the hard disk may be destroyed.
Never turn off the power to the CNC while using its functions, especially
the FTP server functions.
4 To guard against hard disk failure, back up the files on the hard disk.
NOTE
1 One of the following option functions is needed when the Data Server
functions are used:
For details, see the item of "Ethernet boards or Data Server boards and
CNC options" in Section 3.1, "CNC", in Chapter 3, "OPERATING
ENVIRONMENT" of Part I, "OVERVIEW".
2 The Data Server function imposes an upper limit on the number of FTP
clients connectable to one CNC. For details, see the note on Usable
CNCs (When the Data Server is used)" in Section 3.1, "CNC", in
Chapter 3, "OPERATING ENVIRONMENT" of Part I, "OVERVIEW".
