SW Redundancy Features 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 Sum appr. 1,1 s Principle Positioning Application Fields Configuration Features Order number and delivery form

SW Redundancy Features 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 Principle Positioning Application Fields Configuration Features Order number and delivery form
