2.3.3 E-Mail
How it works
The SMTP protocol controls the transmission of e-mails. An e-mail consists of one
or two address fields, a subject field and a field for the actual text message.
The text message consists of ASCII characters. The text may contain placeholders
for variables which reference a data value of the local S7-200 system. When the e-
mail is sent, the CP 243-1 IT reads each such value from the local S7-200 CPU
and inserts it in the desired format at the specified location in the message. The CP
243-1 IT makes it possible to send e-mails preconfigured by a user program to an
e-mail server already specified via IP address and an port during the configuration
phase. The e-mail server then sends the e-mail to the e-mail recipient specified in
the address field of the e-mail.
The e-mail server specified in the configuration by an IP address and a port num-
ber must be located in the subnetwork of the CP 243-1 IT or be able to be ac-
cessed via a gateway. If this e-mail server cannot be accessed, the e-mail is sent
to a substitute e-mail server which is also specified when the CP 243-1 IT is con-
figured. If this substitute e-mail server is also not accessible, an appropriate error
message is generated.
Caution
The CP 243-1 IT only monitors whether an e-mail could be delivered to the config-
ured e-mail server. It is unable to tell whether this e-mail was forwarded to and
read by the specified recipient.
Note
Since memory areas of the S7-200 CPU must be read out in accordance with the
configuration when an e-mail is sent, a reset in between or power failure of the S7-
200 CPU may cause the e-mail transmission to be terminated altogether before it
can even be sent.
This means that a message that an S7-200 CPU reset has occurred cannot be
sent via e-mail.
The CP 243-1 IT does not support the receipt of e-mails. The e-mails and the ad-
dress parameters of the e-mail server are configured by STEP 7 Micro/WIN 32.
