Jianjun Wang, Zhi Feng Liu, Kai Ji · Applied Mechanics and Materials · 2013
This paper analyses the master station redundancy technology in the POWERLINK network. Through the monitoring network and data refresh to achieve the master station redundancy function. The Managing Node redundancy ensures the POWERLINK cycle production continuance after the failure of the current master station, the switch-over time (recovery time) of the POWERLINK system is in the two POWERLINK cycle time at least. That ensures a very fast restoring of normal operation without any downtime for the control system.
