Softing
OPC UA plus Ethernet TSN
Softing will be presenting the first implementation of the Pub/Sub model in OPC UA at the Hannover Messe 2016 - in conjunction with the Ethernet standard TSN.
Softing is convinced that the OPC UA publisher/subscriber communication model is ideal for the requirements of Industry 4.0 and IIoT applications and is currently in the specification process at the OPC Foundation. The communication technology specialist from Haar near Munich claims to be the first provider to implement the publisher/subscriber extension of the OPC UA standard as a prototype model. The corresponding model application uses a standard Ethernet network for deterministic data exchange and uses the IEEE Time-Sensitive Networking standard - TSN for short.
In detail, the OPC UA publisher/subscriber application shows the guaranteed execution of communication between controllers and deterministic communication via an existing TSN infrastructure. Control tasks and data traffic run over a common TSN-capable Ethernet network without jeopardizing real-time data exchange or wasting bandwidth.
Softing will also be presenting the new version 4.10 of the so-called 'dataFeed OPC Suite' at the joint OPC Foundation stand. This now provides OPC UA client functionality and can be used in a wide range of OPC UA gateway solutions. Controllers with an integrated OPC UA server - for example from B&R or Beckhoff - but also the RFID reader from Harting can be easily integrated into existing OPC Classic environments in this way. According to Andreas Röck, OPC Product Manager at Softing, this enables users to implement Industry 4.0 solutions step by step using their existing OPC Classic components.
The 'dataFeed OPC Suite' also provides logger functionality for OPC UA servers. Process data from a controller with an integrated OPC UA server can thus be saved in a file or a database. Using the new OPC UA client functionality, the suite not only serves as a gateway between classic and UA applications, but also acts as a central gateway between several OPC UA servers and clients. The clients only need to connect to one UA server or only one aggregated UA address space needs to be managed.
