Edge computing with POWERLINK

EPSG presents edge-capable controllers at Hannover Messe

The Ethernet POWERLINK Standardization Group (EPSG) will be taking advantage of the Hannover Messe to demonstrate the implementation of edge computing architectures for the Industrial IoT. In addition to edge-capable controllers, Booth F25 in Hall 9 will also exhibit a new rotary joint that can transmit POWERLINK signals at 100 Mbps contact-free.

Numerous EPSG members will have controllers on display that perform data preprocessing and send aggregated information directly to the cloud. These solutions make edge computing architectures easy to implement. Communication with the cloud relies on OPC UA transmitted via the AMQP or MQTT protocols.

Another highlight of the EPSG booth will be a live robotics demo featuring a contact-free rotary joint from SPINNER. These no-wear devices transmit POWERLINK data with the full speed of 100 Mbps. The bit error rate is less than 1x10-12. Increased cycle times due to faulty data packets like those that can occur in slip-ring systems are a thing of the past.

At Hannover Messe 2017, the EPSG will be presenting controllers for implementing edge computing architectures.
