Email notification

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).

Example of email notification with OPC and SQL data

In this example, data is loaded from OPC UA with the OPC UA Client Plug-in and from a Microsoft SQL database with the Microsoft SQL Plug-in. They are supplemented by variables, constants and a file as an attachment. The file for the attachment is loaded with the script function from the OPC Router Basic Plug-in. All data is finally written into the email template and the email for the alert is created. In this example, the email is sent when an OPC trigger is triggered, which checks the data point of a PLC for an alarm condition.

Achieve more with combined Systems

In production, systems work with important data – data that is vital for the production value chain. Easy connectivity, which is established with the OPC Router, seaks to get the right data to the right people just in time, making production a value-rich experience by optimizing data transfers.

Industry 4.0 via Email

Industry 4.0 relies on fast and automated data exchange. The Email plug-in keeps human communication in focus and ensures optimized information distribution.

About OPC Router

The OPC Router offers a visual network configuration interface for successful cross-linking of your systems. A high variety of plug-ins turn the OPC Router into a powerful data hub for industrial applications.
Easy configuration, sophisticated monitoring and robustness are main distinguishing features of the OPC Router.

Combining Systems

That’s how easy it is.

Transfer Objects

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.

Trigger Functions

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).

How do Transfer Objects, Trigger and Browsing work?

The connections the OPC Router establishes between systems can be addressed with the core functions of the OPC Router. Depending on the nature of the respective plug-in, functions vary, which is due to the functional scope of the respective connceted systems.

Transfer Objects

Sources and Destinations

Transfer objects are the sources and destinations inside the OPC Router. They contain data fields with read and write functions. Depending on the respective interconnected system, the possible configuration scope of sources and destinations may vary.

Homegeinity on the Outside – Heterogeinity on the Inside

Inside the OPC Router configuration, the transfer object abstracts the respective system of any connected system into a simple data input and data output block.

Trigger Functions

Prompting Connections

Triggers determine execution time of data connections. Various Triggers can be used for these connectiongs, independent of transfer object type.  Within each connection, several triggers can be used together via AND/OR-connections.


Searching and Finding Data Fields

Easy browsing also makes data field configuration easy when establishing transfer objects in order to establish the respective interface connection. The browsing mechanisms may vary, depending on the system and its available plug-in.

Reading out Structures

Many plug-ins that are available for the OPC Router offer easy search and selection tools for quick identification of respective data fields without the need for specific knowledge about inherent subsystems. The user can easily browse through the data. Data source structures may vary according to the specification of each respective plug-in.
