Master slave switchover time dependant on:
CPU-Type
number of I/O and number of DP-slaves
volume of data to be transfered
communication device
Example with 2 CPU 414-2 DP, 4 DP-Slaves, 4 kBytes Data, communication throught Profibus
Data transfer time appr. 1 s
DP-Slave swithover appr. 20 ms
Fault detection time appr. 100ms

SW RedundancyFeatures
Switchover procedure Outputs are beeing frozen during the switchover
After the switchover, the transfered data are used
Switchover reasons Master failure (Power off or CPU-STOP)
Failure of the Profibus-DP of the master controller
Manual switchover
Memory requirement is 10 kBytes
STEP7 V 4.02 is required
