RFID-AutoID (OPC UA)

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 and Siemens.

Example access control via RFID AutoID and OPC UA

Reading of RFID tag data as soon as a tag is in the reading field and query of access from a database with forwarding of access rights to a PLC via OPC UA.

Achieve More with Combined Systemen

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

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 RFID AutoID (OPC UA) plug-in has transfer objects for various activities with the RFID tags:

SychnonousRead

Synchronous reading of RFID tags

ReadTag

Reading RFID tag information reported by the reader in the reading field.

WriteTag

Describe tags reported by the reader in the reading field.

LockTag

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.

KillTag

Destroy a tag in the read field.

SetTagPassword

Setting the access password of RFID tags.

Trigger Functions

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.

Browsing

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.

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.

Browsing

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.
