7.1 FTP client function of the FP Web-Server

52
The FP Web-Server can send files via FTP, e.g. a daily report or a data
logger file (see p. 61). An existing FTP server can be connected to send the
reports and data sheets of the FP Web-Server. The FTP client is used to
distribute the files triggered by the PLC. The PLC must support the
command with the operation mode. The command line is compatible to the
e-mail attachment operation syntax. In this case, the FTP client function
can also be used in existing projects with small changes. Some additional
commands for SD memory card operation (see p. 53) are implemented.
After a predefined interval, e.g. every 7 seconds, the FP Web-Server
checks an internal data register of the PLC (via MEWTOCOL) to find out if
the PLC wants to send a file. The polling interval between PLC requests
(and the address of the PLC internal data register that starts the sending of
the file) can be defined in the Configurator project.
If the http/https server and/or the Ethernet<->RS232C/RS485/USB ports
are carrying out MEWTOCOL communication with the PLC at the same
time, the polling time can take longer than specified in the setup. Especially
when carrying out multi-frame MEWTOCOL commands (PLC program
