SmtpFull sample with features

With the FB_SmtpFull very extensive email functionalities are available for the PLC.

Description

These possibilities are shown in the sample:

Among other things, the email text is transferred in HTML code, which offers completely new formatting possibilities.
Furthermore, the priority of an email can now be set or read receipts can be requested.
Multiple files can be sent as attachments.

An email is sent after triggering the variable bStart.

ToDo: configure the mail server address, the credentials and the paths to the file attachments.
