POWERLINK – The open standard for the plastics industry

Fast reactions, precise synchronization

Berlin, (PresseBox) - POWERLINK is better suited for industrial communication in the plastics indus-try than any other system on the market. Extremely fast reactions are essential for plastics processing, where response times below 0.5 milliseconds are re-quired even for basic switching operations. POWERLINK provides a lag-free infrastructure featuring communication cycles in the range of a few hundred microseconds, making it particularly well suited for closed loop control systems like these. Utilizing cross-traffic, this real-time protocol is able to syn-chronize multiple axes with exceptional precision.

728 axes in 400 µs

The world's fastest network to date has been implemented in a plastics applica-tion using POWERLINK. This two-dimensional foil stretching machine from Brückner Maschinenbau GmbH & Co. KG features 728 axes synchronized with a cycle time of 400 µs. Performances like this make POWERLINK the clear choice for the plastics industry.

As early as 2010, EUROMAP (the European association for plastics and rubber machinery manufacturers) had already incorporated the POWERLINK standard in the EUROMAP 75 specification. "The EUROMAP specification underscores POWERLINK's leading position among protocols with hard real-time capabili-ties," says Stefan Schönegger, managing director of the Ethernet POWERLINK Standardization Group.

About EPSG

The Ethernet POWERLINK Standardization Group (EPSG) is an independent organization founded in 2003 by leading companies from the fields of motion control and automation technology. Its aims are the standardization and further development of the POWERLINK protocol first introduced by B&R in 2001. This high-performance real-time communication system is an advanced protocol based on the IEEE 802.3 Ethernet standard designed to ensure real-time data transfer in the microsecond range. The EPSG cooperates with leading standardization organizations such as CAN in Automation (CiA) and the IEC. Anton Meindl, business manager of Controls at B&R, is the organization's CEO.
