1.6.2 Types of communication
In addition to the S7 communication relations described in chapter Types of communication
(Page 15), the CP 243-1 allows four types of IT communication relations that can be used
individually or as a combination.
1.
Communication with an e-mail server
2. Communication with an FTP client located on a remote system.
3. Communication with an FTP server. Such a server is typically located on a remote
system. A link to the FTP server running on the CP 243-1 of the local S7-200 system is
also possible.
4. Communication with up to four Web browsers running on remote systems
1.6.3 E-mails
How it works
The SMTP protocol controls the transfer of e-mails. An e-mail consists of one or two address
fields, a subject field and a field for the actual text message.
