Features and Functions
To ensure consistency with large amounts of data, appropriate measures must be
provided in the S7-200 application program.
When a transmission between the FTP client of the CP 243-1 IT and an FTP
server is interrupted, only part of the transferred data may have been stored on the
destination system. In such cases, an error message is output by the S7-200 user
program. The transaction is not repeated automatically.
On the CP 243-1 IT, data communication via FTP is subordinate to S7 communica-
tion. Reaction times vary with the particular configuration as well as the length of
the S7-200 application program and generally cannot be predicted in advance.
Note
The file DB routine of communications processors CP 343-1 IT and CP 443-1 IT is
not supported by the CP 243-1 IT. The CP 243-1 IT reads or writes one binary im-
age of the data block from/to a file. This file contains no other information on
length, source address, and so on.
