1) 
When 
PROFIBUS and PROFINET are used, the total address space applies: All I/O are assigned in 
the logical I/O address space. The maximum number of I/Os is limited by the number that can be 
addressed using the logical I/O address space.
2) 
A second PROFINET interface for the D4x5‑2 DP/PN Control Units is optionally available for the 
CBE30-2.
