Zebra Printers / ZPL.
Zebra printers are extensively used for labeling in industrial plants. Zebra printers receive printing information via ZPL, which stands for Zenbra Programing Language. ZPL is also used in labeling systems.
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.
Industrie 4.0 for Zebra Printers
Making use of the OPC Router in connection with the Zebra Plug-in dispences of manual configuration efforts of printing data in ZPL-compatible printers. Instead, the printer is now part of an Industry 4.0 infrastructure.
About the OPC Router
That’s how easy it is.
The transfer object of the Zebra plug-in contains ZPL commands for printing.
The configured template contains ZPL command sequences, and can also be enhanced with dynamic fields. During transfer the dynamic fields are filled with transferred values first. Once this has occurred, the now current ZPL command sequence is sent to the printer.
The Zebra plug-in does not have trigger functions of its own but uses the standard trigger functions the OPC Router offers.
The Zebra plug-in extracts the filled-in dynamic parameters from inside the comman sequence and makes it available for selection.
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.
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
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.
