FTP Server Section 2-4
2-4 FTP Server
The Ethernet Unit has a built-in FTP server function, so other computers on
the Ethernet can read or write individual files in a Memory Card mounted to
the CPU Unit or in EM file memory. This allows files to be exchanged between
the host computer and the PC, with the host computer functioning as an FTP
client and the PC as an FTP server. For details, refer to Section 7 FTP Server.
2-5 Mail
Data such as user-created information (1,024 bytes max. in ASCII), Ethernet
Unit error log information (64 records max.), and status information can be
sent as e-mail to specified addresses.
The e-mail can be sent with any of the following three types of timing. (Simul-
taneous specification is also possible.)
• When the Mail Send Switch turns ON.
• When an error occurs (when an error log is recorded.)
• At regular intervals.
This enables periodic e-mail and error messages to be sent from the PC to
the mail server.
Note 1. A mail server is required in order to use the mail function.
2. Mail server settings require specialized knowledge, so they should always
be handled by the network administrator.
3. Be sure you have a clear understanding of the mail system before using
this function.
