2.2 Configuring H CPUs

2.2 Configuring H CPUs
Introduction
You create two redundancy connections between the H-CPUs via fiber-optic cables using a
total of four synchronization modules (two in each H-CPU). You replace the synchronization
modules (for cables up to 10 km in length) in STEP 7.
STEP 7 automatically assigns an IP address to each PROFINET interface of a CPU. You
can also assign the IP addresses manually. For PROFINET interface X1 of the CPUs, the IP
addresses must be located in the same subnet. In the example you accept the preset IP
addresses.
STEP 7 assigns default values for the minimum and maximum cycle times. Select the
minimum scan cycle time so that the cyclic program does not have to be executed more
frequently than your process requires.
