Configuring the
Mail Service
As an authorized administrator, use the SMTP Configuration Web page to:
z configure the service
z set the IP address of the mail server
Elsewhere in this guide is detailed information about configuring the electronic mail
service (see Configuring the Mail Service with the Email Configuration Page, p.
295).
Message
Creation and
Delivery
A user-defined event or condition triggers the MSTR block to create a message.
Each message uses one of three user-defined headers. Each message sent from
the controller can contain text and variable information (with a maximum of 238
bytes).
The project selects the appropriate header. Each header contains:
z sender name
z list of recipients
z subject
Header
Examples
The text and variable information can be defined and updated by an authorized
administrator using an embedded Web page (SMTP Configuration page). Define
mail headers to indicate different levels of importance. For example:
z Header 1 could be "Urgent problem reported by PLC 10"
z Header 2 could be "NOTIFICATION from substation 10"
z Header 3 could be "INFO message from water system"
Listing different recipients in each of the three headers ensures that the right
information quickly flows to the right recipients. The project adds pertinent
information such as the specific device, process, or location. This pertinent
information is added to the body of the mail message. Then the complete message
is sent to an electronic mail server for distribution to recipients. These recipients
could be engineers, managers, or process owners.
Security
(Authentication)
An optional login (system ID) and password can be used to authenticate the
connection to the SMTP mail server. The SMTP-supported authentication method is
LOGIN.
System
Diagnostics
The SMTP Diagnostic Web page displays the status of the service. Diagnostic
information is also available for remote management using the SNMP network
management standard.
Note: Default TCP Port: The default TCP port number for SMTP is 25. Ensure that
you configure the port specified by your local mail server.
