RFID via AutoID Standard
Working with RFID readers has long been characterized by manufacturer-specific protocols and connection types. With the OPC UA AutoID Companion Specification, this has now fundamentally changed. In the specification, communication with the reader is standardized and the communication protocol is set to OPC UA. Thus, manufacturer independence is achieved on the application side.
The OPC Router implements the RFID part of the AutoID specification and is therefore able to easily connect compatible RFID readers and integrate them into industry 4.0 environments. AutoID compatible readers are available e.g. from Harting, Siemens and TURCK.
Achieve more with combined Systems
By the simple integration of RFID readers with the new standard, different systems can be fed with RFID data in a simple way and processes can be controlled more efficiently.
Industry 4.0 with RFID AutoID
For industry 4.0 it is essential to provide the right information about workpieces and raw materials to the right systems at all times. The simple integration of RFID-AutoID systems makes it possible to supply any system at any time with important identification data, which can then be used to determine the associated production data. RFID data is no longer reserved for special isolated solutions.
About the OPC Router
That’s how easy it is.
The RFID AutoID (OPC UA) plug-in has transfer objects for various activities with the RFID tags:
Synchronous reading of RFID tags
Reading RFID tag information reported by the reader in the reading field.
Describe tags reported by the reader in the reading field.
Blocking an RFID tag in the reading field. The password must also be transferred for later access to a tag. The password functionality is supported for all functions defined in the standard.
Destroy a tag in the read field.
Setting the access password of RFID tags.
The RFID-AutoID (OPC UA) plug-in has a trigger.
The Asynchronous Scan Trigger triggers a connection as soon as one or more RFID tags are found in the reading field and have been read.
All fields defined in the AutoID Specification for handling RFID tags are defined in the OPC Router RFID AutoID (OPC UA) Plug-in are automatically provided in the connection.
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 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.
