The CP uses authentication, the mail server does not
If you use a CP that supports authentication and you want to work without authentication,
do not store a user name or password in the e-mail data block (see section Sending an e-
mail (Page 141)). In this situation, the CP transfers data using SMTP.

The mail server uses authentication, the CP does not
The mail server aborts the attempt to send.
Procedure
Follow the basic steps below to send e-mails:
Clarify mail server mode:
• Is there already a mail server in your network environment?
• Who can set up access for the CP?

• Configure the email connection
By configuring an e
mail connection you allow establishment of a connection between the S7 CPU
and the Advanced CP for sending emails.
See section Setting up an e-mail connection (Page 139).

You can check the availability of the email
function at any time by initiating a test mail on
