Configuration
Placeholders for data from the S7-200 system can be inserted in the actual e-mail
text to be sent. When the e-mail is sent, the CP 243-1 IT replaces each of these
placeholders with the current value of the data.
To insert such a placeholder in your e-mail, click "Insert Data". In the screen which
appears, create the placeholder to be inserted. Specify the address of the data to
be transferred and the format in which this piece of data is to be indicated in the e-
mail.
A total of up to 32 different e-mails can be configured.
As soon as you have configured the desired number of e-mails, click "Next" to exit
the e-mail wizard.
Then either branch to another wizard or conclude the configuration of the CP 243-1
IT by clicking "Finish".

Configuration of the FTP Functions
To branch to the wizard for configuring the FTP functions, click the appropriate icon
in the left-hand box of the screen. All the information entered in this wizard is
stored in the file system of the CP 243-1 IT in a file with the ending .fdb when the
configuration is loaded to the S7-200 system.
Using the FTP wizard, you can configure the FTP jobs which are to be sent from
your S7-200 user program via the FTP client on the CP 243-1 IT.
The FTP server does not need to be configured. This server is automatically
started by the CP 243-1 IT during startup. Access rights to this FTP server are
specified in the configuration of the user administration.
Configuring the FTP jobs
To configure an FTP job, you must first specify whether this is a read, write or de-
lete job and the FTP server to which the job is to be sent.
With write jobs, enter which data from the memory of your S7-200 CPU you want to
send to the specified FTP server. The start address and the length of the data to
be transferred are required.
With read jobs, specify whether the received data are to be stored in the memory
of your S7-200 CPU. Also specify how many bytes are to be transmitted. If you en-
ter a zero as the length, the entire contents of the specified file are copied to the
memory of your S7-200 CPU, starting at the specified start address.
Caution
The CP 243-1 IT and the FTP wizard are only able to perform very limited plausibil-
ity checks on the address and length information entered when the FTP jobs are
configured.
In particular with read jobs, only a rudimentary check can be made as to whether
system or user data are overwritten in the memory of the S7-200 CPU based on
the specified address and length information. This is the general responsibility of
the user.
