Overview
Introduction Since not all machines of a plant can be continuously monitored by the staff, pending messages from the SCADA system can often not be responded to quickly. An e-mail notification is to alleviate this problem. Overview of the automation task The figure below provides an overview of the automation task. Figure 1-1

SCADA System
1.2
Description of the automation task If a message appears, an email is to be sent to the respectively responsible member of staff. Setting the email user account and maintaining the email recipient is to be possible while Runtime is running. The stored data is to be saved non-volatile and loaded when Runtime is started. The email recipient is to be set shift by shift. Additionally, it is to be possible to change the times of the shift when Runtime is running. For test purposes, the sending of emails is also to be possible with free email providers.

Advantages The application on hand offers the following advantages: •
You are using a standardized means of communication via email notification. Messages can therefore be send to all email clients, e.g. also to smartphones.
•
You increase safety, since it can be quickly reacted to the event. Even also if the machine operator is absent.
•
An email notification sends information directly to the executing department such as sales or workshop. The required activities can be implemented instantly since the necessary information is instantly available and does not need to be read on the SCADA system first.
•
You can change the email addresses directly on the SCADA system and save it reliably via the non-volatile management. This makes you flexible and protects you from data loss.
•
Through our tests of free email providers you save time-consuming tests and reach your goal faster.
•
With our extensive templates you reduce the configuration phase for email notifications to a minimum.

Alternative solutions Event Notifier For SIMATIC WinCC V7.0 SP2 Upd4 there is the Event Notifier V7.0 SP2. http://support.automation.siemens.com/WW/view/en/54064299 The SIMATIC WinCC/Event Notifier option offers a calendar-based user interface in the style of Microsoft Office for the simple and secure planning of notifications of selected persons in defined time windows. The option consists of a calendar control and editors with which notifications and contacts can be configured and managed as potential targets for notifications. Notifications are assigned to immediately selectable events in the WinCC message system at the time of configuration. Contacts can also be recruited at Runtime from the WinCC user administration.
Copyright Siemens AG 2012 All rights reserved
A communication service editor makes it possible to establish the communication service via email service at the time of configuration, i.e. the notification triggered at a certain event in the WinCC message system is generally sent via email. The email can be directed as text message (SMS) to your mobile phone via provider gateway if the respective contact has been set up accordingly and the person has enabled this service from his/her provider. If several people or groups of people are created in parallel for one and the same time window in the calendar control, various escalation times can be realized via the specification (= dead time before notification) of escalation steps.

This data can be changed after the Runtime start and subsequently saved in the files. (see chapter: 5.1 Setting of the SMTP server and 5.2 Setting and managing the recipient addresses) If an email is to be sent, the following is distinguished: •
email with individual recipient The email address of the recipient is directly specified on the function.
•
