Secure and seamless communication with POWERLINK and OPC UA

26 February 2018

A joint announcement by the OPC Foundation and the Ethernet POWERLINK Standardization Group (EPSG) confirmed that an OPC UA companion specification is now available for POWERLINK.

The companion specification describes how payload data is exchanged between POWERLINK and any OPC UA platform to enable integrated communication from the sensor to the cloud.

Thomas Burke, president of the OPC Foundation, said: "OPC UA and POWERLINK complement each other perfectly. POWERLINK is among the leading real-time bus systems used in plants and machinery. Together with OPC UA, POWERLINK networks can now communicate seamlessly and securely with the IT environment and into the cloud."

Stefan Schönegger, managing director of the EPSG said: “This specification allows OPC UA and POWERLINK to fuse into a single network. We are then able to join devices from different manufacturers and across different levels of the automation pyramid into a single, cohesive system. A joint working group between the OPC Foundation and the EPSG had been working on the specification since 2016.
