POWERLINK and openSAFETY for construction machines

Once an important step ahead and still the undisputed, recognised data communication 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 openSAFETY safety protocol. While seamlessly field bus integrated, it is independent 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 fulfil 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 enhances the availability of mobile machines.
