A New Dimension of Data Transfer and Equipment Safety
Once an important step ahead and still the undisputed, recognized data com-munication standard in vehicles, the CAN bus is reaching its limits due to ever more intelligent sensors and constantly rising masses of data. The fast real-time Ethernet POWERLINK solves this problem adequately and in a future-proof manner. As an Ethernet-based protocol, POWERLINK comes standard with a high communication bandwidth. Thus, it can provide even the most demanding sensor systems or imaging technology applications with sufficient data transfer capacity without any need for software or hardware adaptation.
Implementation of safety measures according to the currently valid 2006/42/EG EC machinery directive and the applicable standards is eased by the open-SAFETY safety protocol. While seamlessly field bus integrated, it is independ-ent of the communication protocol used. Safety-relevant signals tunnel through the underlying transport layer of protocols such as POWERLINK.
This renders separate wiring of the safety components unnecessary, as those are connected to the network just like all other components. Thus, modules and devices that have to fulfill certain safety requirements but are not permanently attached can be included without additional effort for cabling. Direct integration with the standard network also reduces reaction times and extends options for diagnostics. This greatly enhances the availability of mobile machines.
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.
