6.1 E-mail functions of the FP Web-Server
A) Using an e-mail server via Ethernet LAN:
FP Web-Server V2.810 EN
The FP Web-Server can send e-mails, e.g. in case of an alert. An existing
e-mail server (see p. 49) is used to distribute the e-mails triggered by the
PLC. The PLC can use predefined text messages (stored in the FP
Web-Server) as well as variably created e-mail texts (stored as ASCII
strings in the PLC). The FP Web-Server informs the PLC if the e-mail has
been sent correctly.
After a predefined interval, e.g. every 7 seconds, the FP Web-Server
checks an internal flag of the PLC (via MEWTOCOL) to find out if the PLC
wants to send an e-mail. The polling interval between PLC requests (and
the address of the PLC internal flag that starts the sending of the e-mail)
can be defined in the Configurator project.
Optionally, a file attachment holding PLC data can be generated.
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 ís longer than specified in the configuration.
Especially when carrying out the multi-frame MEWTOCOL commands (PLC
program download) via the Ethernet<-> RS232C/RS485/USB ports, the
e-mail polling of the PLC internal flag can be delayed.
For examples on sending e-mails from the PLC, refer to the PEW_FPWEB
library or try the examples below.
Please ask your network administrator whether the following
requirements are met:
An e-mail SMTP server in the LAN is required. Also refer to setup of an
individual Ethernet LAN (see p. 181).
The address of the e-mail server must be correct in the Configurator
project.
A defined e-mail address, which is known to the e-mail-server, should
be assigned to the PLC (or the FP Web-Server).
