Gen. Barcode Reader

Generic bar code reader.

Barcode readers, connected via RS232 to the COM port of the PC, are the simplest variant of barcode readers in industrial environments. These barcode readers normally supply a character string with the barcode information after the scan. The OPC Router Plug-in for generic bar code readers enables the reception and further processing of the character string.

Achieve More with Combined Systems

If the barcode reader is connected to the OPC router, the scan data can be transferred directly to other systems.

Industry 4.0 with Barcodereader

The simple scan can have far-reaching consequences due to the transmission of the data through the OPC router. Processes can make immediate decisions based on the identification made and the information about it. This achieves the goal of networked and self-controlling production in industry 4.0.

About the OPC Router

The OPC Router offers a visual network configuration interface for successful cross-linking of your systems. A high variety of plug-ins turns 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 generic barcode reader plug-in does not have a transfer object, since the data is made available by the trigger object after receipt.

Trigger Functions

The generic barcode reader plug-in provides a receive trigger for barcodes. After receipt, the transfer is triggered and the barcode including all basic data is available in a data field.


The generic barcode reader plug-in does not use browsing.

How do Transfer Objects, Triggers 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 connected 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. Thus, the functions can be treated in the same way although each connected system has very individual features.

Trigger Functions

Prompting Connections

Triggers determine execution time of data connections. Various triggers can be used for these connections, independent of transfer object type. Within each connection, several triggers can be used together via AND/OR-connections. Triggers can also be useful as data sources if the prompting event is combined with data reception.


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.
