S HTML process control
With some CPs (for example Advanced CPs), use the supplied functions and
HTML pages to query important system data using a Web browser (see
Chapter 10).
S File management and file access with FTP
The CPs with IT functionality (S7-400 / S7-300) provide additional functions for
FTP services.
You can use your S7 station both as an FTP client and as an FTP server (see
Chapter 9).
− S7 Station as FTP Client
You can transfer data blocks from or to a file server.
− S7 Station as FTP Server
Another station, for example, a PC transfers data blocks to or from the S7
station the file system on the CP with IT functionality.
S E-mail communication
CPs with IT functions provide E-mail services.
This allows the controller to send messages dependent on process events (see
Chapter 8).
