■ Overview
CR2 (Central Rack)
• For setting up central controllers
• For holding up to 18 modules
• Segmented rack:
For operating two mutually independent S7-400 CPUs without
S7-400 Multicomputing, but with communication between the
CPUs over the backplane bus (C bus). Both CPUs can
address their own local I/O modules (segmented P bus).
CR3 (Central Rack)
• For configuring central racks
• Optimized for distributed automation solutions due to holding
up to 4 modules
UR2-H
• For configuring a complete S7-400H system in one subrack
• Also suitable for S7-400:
Operation of 2 separate CPUs with their own I/O
• The basic mechanical framework of the (separate P and C buses)
SIMATIC S7-400/S7-400H
• For accommodating the modules, supplying them with
• Can also be used as an expansion unit
• For holding up to 18 modules 6
