Hardware configuration
Number of distributed IO systems 32; A distributed I/O system is characterized not
only by the integration of distributed I/O via
PROFINET or PROFIBUS communication mod-
ules, but also by the connection of I/O via AS-i
master modules or links (e.g. IE/PB-Link)

PROFINET, Ethernet) can be inserted in total
Number of IO Controllers
• integrated
1
• Via CM
6; A maximum of 6 CMs/CPs (PROFIBUS,
PROFINET, Ethernet) can be inserted in total
