Wolke Inkjet Printers

Wolke Thermal InkJet Printers.

Wolke printing systems print with ink and at very high resolutions. Printing products are used in industrial applications for product  labeling. The printers are integrated into industrial plans and can be addressed from inside the company’s network architecture. The printing setup allows various layouts that can be called upon before  printing. Besides the possibility of manual data entry into pre-configured fields, it is also possible to retrieve data via the OPC Router through the available network connection.

Achieve More with Combined Systems

Printing systems take on important product labeling tasks. Wrong or missing labels can result in sizeable economic damages. When a printers is connected with the OPC Router, data exchange can take place coherently, which rules out human errors by tapping into the data source immediately.

Industry 4.0 with Wolke printers 

Manual configuration is a thing of the past if the OPC Router and the Wolke printer plug-in work together inside an industry 4.0-enabled infrastructure.

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 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 Wolke plug-in contains information about layout and fields used for printing.


The layout determines the respective format and print design, which is referenced by a unique name in the printer’s interface. In the transfer object the respective layout name is the reference point for further action. The respective selected layout can be pre-configured in the transfer. It can also be dynamically determined, which enables processing of printing tasks for various layouts per production job without increasing configuration efforts or configuration time spans, as manual configuration is rendered obsolete, if configuration is Industry 4.0-enabled.


Each and every layout contains clearly identifiable fields. These fields are registered in the transfer object, and thus become available as data fields for respective transfer configurations.

Trigger Functions

The Wolke plug-in does not have trigger functions of its own but uses the standard trigger functions the OPC Router offers.


The Wolke plug-in presents pre-configuted fields as data fields. Additionally, information is provided about the label name, IP address, and printing port, which are also generated as data fields.

How do Transfer Objects, Triggers and Browsing work?

The OPC Router establishes connections between systems that address core functions of the OPC Router.

Functions of the respective plug-ins may vary, due to the different nature of each connected system.

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.
