At this point, this is to be remedied by e-mail notification. Introduction Overview of the automation problem The figure below provides an overview of the automation problem. Figure 1-1 Copyright Siemens AG Copyright-2012 All rights reserved ! Alarm ? Ethernet Internet/ Intranet Process ! 1.2 Description When alarms of specific alarm classes occur, the relevant employee is to be informed. The employee to be notified is to change depending on early, late or night shift. It is to be possible to manage the e-mail recipients directly on the operator panel. The stored e-mail addresses are to be saved on a non-volatile basis. For test purposes, it is to be possible to send e-mails even with free e-mail providers. Description of the automation problem 6 E-Mails Comfort Panels V1.0, Entry ID: 56720728 2 Solution 2.1 Overview of the overall solution 2 2.1 Solution Overview of the overall solution The diagrammatic representation below shows the most important components of the solution: Figure 2-1 Diagrammatic representation E-Mail Service/Server INTERNET INTRANET ! Alarm Copyright Siemens AG Copyright-2012 All rights reserved Comfort Panel Ethernet Process E-Mail Client Mobile E-Mail Client Advantages This application offers you the following advantages: • • • Through e-mail notification, you use a standardized means of communication. Alarms can thus be sent to all e-mail clients, e.g. also to smartphones. They increase the probability of a prompt reaction, even in the event that the machine operator is absent. E-mail notification also sends the information directly to the relevant department, for example purchasing or workshop. Therefore, the necessary activities can be implemented immediately as the respective information is already available and does not have to be read from the operator panel first. You can change e-mail addresses directly on the operator panel and reliably save them using the non-volatile recipe management of the Comfort Panels. This provides you with flexibility and protection against loss of data. Our tests of free e-mail providers with secure SSL encryption save you complicated, time-consuming testing and enable you to reach your goal faster. Our comprehensive application example allows you to reduce the familiarization necessary for “E-Mail Notification with the Comfort Panels” to a minimum. • • • E-Mails Comfort Panels V1.0, Entry ID: 56720728 7 2 Solution 2.2 Description of the core functionality The configuration templates from the application example offer you the option to familiarize with the topic in a short time.
