System configuration
In an environment where the Internet is available, e-mails can be sent. (Since the mail server is responsible for sending e-
mails, the Ethernet module does not directly send e-mails to the Internet.)
Set each setting value of e-mail for Ethernet modules, personal computers, and other devices according to the instructions by
the system administrator.
To set the parameters of the Ethernet module to use the e-mail function, use the engineering tools or sequence programs.
