New firmware 4.0 for modular managed switches and managed compact switches
The new firmware 4.0 is now available for the industrial Ethernet components modular managed switch (MMS) and managed compact switch (MCS).


The highlight of the firmware 4.0 is the optimized redundancy support; the expansion of the Rapid Spanning Tree protocol Fast Ring Detection attains switchover times of max. 100..500 ms in the case of media failure. A max. switchover time of 500 ms results for large automation networks with 1000 address table entries in the switches. These times are shorter if there are fewer address entries or terminals in the network.
