Function overview
This function enables e-mails to be sent via mail servers over networks to personal computers or smartphones in remote
locations.
The programmable controller sends e-mails by using a module function block in a ladder program.
When an error occurs in the Ethernet module, this function can send a notification with device data attached as detailed
information to the mail addresses of users.
This function supports the TLS encryption function and enables connection to a free mail server.

Sending
an e-mail
(1) The Ethernet module sends the e-mail to the outgoing mail server.
(2) The outgoing mail server sends the e-mail to the incoming mail server of the send destination device.
(3) The personal computer uses the e-mail software to receive e-mail.
The e-mail function enables the programmable controller to create an e-mail message whose body or attachment contains the
device data of a station in which the Ethernet module is mounted, and send the message to personal computers,
smartphones, or other external devices. The attachment is used to send device or other data that is converted and encoded
into binary, ASCII, or CSV (ASCII) data format.
The subject and message body are used to send ASCII or UTF-16 data (string data) created with a sequence program.
(When UTF-16 data is selected, it is converted to UTF-8 by the intelligent function module.)
