Email notification via SMTP
Email remains one of the simplest and most common notification and alerting methods. The Email notification Plug-in works with the simple SMTP protocol and thus has easy access to almost any mail system. With the Email notification Plug-in you can create your own email templates for various alerting functions and fill them at precisely definable times with data from connected systems such as OPC UA, SAP, SQL databases, REST, MQTT and many more.
The graphical designer allows you to project your own email alerting according to application-specific requirements (see example).
That’s how easy it is.
The transfer object of the Email notification plug-in offers individual email template configurations. When a transfer is prompted the current data is transferred and sent via SMTP.
Text and variables
The text of the email notification can be provided with any placed variables. The variables are described with values during the transfer from outside.
consignees, consignor, subject
The fields consignees, consignor and subject are available as standard data fields for each email and can be freely described with data. Dynamic emails are sent for each application case.
The Email notification plug-in does not have trigger functions of its own but uses the standard trigger function the OPC Router offers.
The Email notification plug-in reads out all variables contained in the email template.
The variables are automatically configured as data fields inside the transfer object and can be written to with any given value of various data types. During the writing process an automatic conversion occurs: The data is converted into a “string” (i.e. sequence of characters).

Notification of exceptional situations
In its connections, OPC Router transfers data between systems, which often have a controlling influence on the process in Industry 4.0 applications. By accessing this data and triggering the connections to certain events, it is also possible to handle exceptional situations. The triggers of a connection can explicitly evaluate signals from the PLC (OPC UA) or specific database queries (SQL Server) and, in exceptional cases, send an e-mail alert to responsible parties via the e-mail plug-in, who can then react to the exceptional situation.
Involving people in Industry 4.0
The e-mail plug-in of the OPC Router enables information from the automated flow of an Industry 4.0 process to be sent as e-mail. The information from the process can be collected by the OPC router from various sources and packed into an e-mail including attachment that can be easily evaluated by humans. If humans are necessary in a process, such an e-mail can be used to inform them precisely with the request and all relevant data in your normal working environment (e-mail client) and to request them to take action. In this way, the Industry 4.0 process and the human being work together optimally.
