2 USING THE E-MAIL FUNCTION
(3) Flow of the e-mail
The diagram shown below illustrates the flow of e-mails from the local station's
Ethernet module to the external device after the monitor values match with the
news conditions.

1) Reads the monitoring information (such as status and device values) of the
PLC CPU.
2) Checks whether the monitoring information read and the news conditions set
by the user match. (Checks match/mismatch of the news conditions.)
3) Sends an e-mail when the monitored values match with the news conditions.
Multiple news conditions may be set so that an e-mail can be sent
(notified) when any of the conditions matches. (See Section 2.9.1.)
Set the CPU inquiry time interval used by the Ethernet module to monitor
the PLC CPU, considering the interval of change time in the monitoring
target.
After a news condition match occurs, the Ethernet module must confirm
the mismatches of other news conditions for the same monitoring target.
The next e-mail can be sent only after the Ethernet module confirms the
mismatches of these news conditions.
4) The Subject of e-mail, which is sent when the notification conditions match, is
fixed data. The format of the Subject is as follows (see Section 2.9.2):
• When monitoring the CPU status
Subject = "Transmission destination No., CPU model name, Status,
Detection time"
• When monitoring the CPU device
Subject = "Transmission destination No., Matched condition device,
Monitoring value, ... "
POINT
The e-mail transmission function of the PLC CPU and the communication function
using the random access buffer can be used together.
