OPC UA – Universal Data Exchange From the Sensor to the Cloud

December 14, 2020

How can the data from intelligent sensors be transferred to the IT level for further processing? This is an important question – because only those who are able to do so can successfully implement Industry 4.0 projects or predictive maintenance. Bihl+Wiedemann’s answer is OPC UA: Many Bihl+Wiedemann gateways feature this open communication protocol. This enables them to transfer the data from the IO-Link sensors directly upstream to the IT world. This data-flow would not be so easily accessible without OPC UA because IO-Link devices do not have any direct TCP/IP connection.

Easy access to a wide range of machine data

By using the OPC UA server in our gateways you can also access a wide range of machine data. A lot of information about the machine and the process, from device diagnostics to process data, can be easily retrieved via the network. Another advantage: By using OPC UA, there is a noticeable reduction of load on the controller and fieldbus.

To ensure data security, Bihl+Wiedemann support, among other things, encrypted OPC UA communication even with customer-specific certificates. This allows the devices to be seamlessly integrated into existing IT security concepts.

Your advantages with OPC UA solutions by Bihl+Wiedemann

  •    –   Easy retrieval of collected data to the cloud, on a local server or even on a visualization tool
  •    –   A data exchange standard for all machine and system components. This eliminates the need to merge and convert data
  •    –   Universal, horizontal integration – from diagnostics on an HMI to networking of different systems across the world
  •    –   Reduction of fieldbus load
  •    –   Integrated certificate-based security solution

Siemens: SIMOVAC Non-Arc-Resistant and SIMOVAC-AR Arc-Resistant Motor Controllers

The Siemens SIMOVAC medium-voltage non-arc-resistant and SIMOVAC-AR arc-resistant controllers have a modular design incorporating up to two 12SVC400 (400 A) controllers, housed in a freestanding sheet steel enclosure. Each controller is UL 347 class E2, equipped with three current-limiting fuses, a non-load-break isolating switch, and a fixed-mounted vacuum contactor (plug-in type optional for 12SVC400). The enclosure is designed for front access, allowing the equipment to be located with the rear of the equipment close to a non-combustible wall.
