Ethernet Unit Function Guide
SECTION 6 FINS Communications
When the mail send function is used, automatic communications applications
via the Internet can be constructed relatively easily. With this Ethernet Unit,
the following mail triggers can be set as PLC changes. When these settings
can be used, no special ladder program is required for sending e-mail.
The following data can be sent by e-mail:
To use the mail send function, there must be a separate SMTP server on the
network. When using the SMTP server of an Internet Service Provider (ISP),
security measures, such as POP before or SMTP, may be required. (This Unit
handles POP before SMTP.) In addition to the IP address, the host name used
for the DNS service can be specified for the SMTP/POP3 server.
• When a particular bit (the Mail Send Switch) turns ON
• When values change in particular words (=, <>, <, <=, >=, >)
• When a particular bit changes (either OFF to ON or ON to OFF)
• When a change occurs at the Ethernet Unit (stored in error log)
• When a change occurs at the CPU Unit (e.g., a non-fatal error, a fatal
• At regular intervals
• Text (user-created text strings (ASCII data), Ethernet Unit error log data,
• Attached files (IOM data created automatically by the Ethernet Unit, data
error, or a mode change)
and status data)
