CP 243-1
108 Operating Instructions, 03/2012, C79000-G8976-C244-02
Status applet:
Using the Web browser, an HTML page can be requested by the CP 243-1 indicating the
status information of the S7-200 system. This page includes, among others, information
on the status of the S7 and IT channels. The call for this page is shown in the first table
together with an overview of the information on this page.
FTP server:
Using the FTP server, the contents of the file system can be changed. If there are effects
that indicate errors in the file system while the CP 243-1 is running, the contents of the
file system on the CP 243-1 should be checked from an FTP client. If necessary, bad files
can sometimes be corrected in this way.
Note
The abrupt shutdown of a CP 243-1 with active client connections (for example due to a
power failure) while the server continues running may result in the server not recognizing
that the connections have been interrupted. When the client then attempts to connect
again, a delay (determined by the configured keepalive time) may occur when the CP
243-1 resumes operation before all connections are reestablished.
Note
During the startup of the CP 243-1, its file system is automatically checked for
consistency. If inconsistencies are found, these are corrected as far as possible.
