Making Real-Time Ethernet a Reality by Ethernet Powerlink

Machines,plants and safety systems are today stuck in a rigid scheme made up of hardware-based safety functions.The consequences of this are cost-intensive cabling and limited diagnostic options. More recent attempts at safety field buses are often characterized by proprietary standards and limited cycle times in the millisecond range.

Machines,plants and safety systems are today stuck in a rigid scheme made up of hardware-based safety functions. The consequences of this are cost-intensive cabling and limited diagnostic options. More recent attempts at safetyfield buses are often characterized by proprietary standards and limited cycle times in the millisecond range.As a result of the rapidly advancing development of Ethernet solutions for automation,these traditional safety protocols will in future be of little signi ficance.
