2 USING THE E-MAIL FUNCTION

2.1 E-mail Function

The e-mail function sends and receives CPU information (programmable controller
CPU status and device values) to/from PCs or programmable controller CPUs in
remote locations via the Internet.
The following two methods are available to send/receive e-mail using this function.
(1) Sending/receiving e-mail by the programmable controller CPU
(2) Sending e-mail using the Ethernet module's programmable

2.1.1 E-mail send and reception by the programmable controller CPU

(1) Sending/receiving e-mail by the programmable controller CPU
Sending e-mail by the programmable
controller CPU (MSEND instruction)

Executed by a sequence program using dedicated instructions.
controller CPU monitor function
Executed by the Ethernet module according to the Ethernet module parameter
setting (news setting) of a programming tool.
In sending/receiving e-mail by the programmable controller CPU, the CPU
information of a station in which an Ethernet module is installed is sent to another
Ethernet modules or an external device such as a PC as the main text or
attached file of e-mail. E-mail sent from other Ethernet modules and PCs can
also be received.

Binary to CSV conversion
: Can receive data.
1 The Ethernet module receives the Subject without decoding.
2 The MRECV instruction is normally completed when a data size (the size the
MRECV instruction receives) after conversion is within 6144 words.
(a) Sending e-mail by the programmable controller CPU (MSEND instruction)
Data transmission is performed via the main text or attached file of e-mail
using the MSEND instruction.
1) For an attached file, device data and other information is sent by
converting into binary/ASCII/CSV data format.
2) For the main text, ASCII code data (character string data) created by a
sequence program is sent.
(b) Receiving e-mail by the programmable controller CPU (MRECV instruction)
Receives attached file data of e-mail using the MRECV instruction. The
main text data of e-mail cannot be received.
