Overview
• The basic mechanical framework of the
SIMATIC S7-400/S7-400H
• For accommodating the modules, supplying them with
operating voltage and connecting them via the backplane bus
• Several versions for configuring central controllers and
expansion racks
UR1 (Universal Rack)
• For setting up central controllers and expansion units
• For holding up to 18 modules
• Also suitable for S7-400H
• Also available as aluminum rack
UR2 (Universal Rack)
• For setting up central controllers and expansion units
• For holding up to 9 modules
• Also suitable for S7-400H.
• Also available as aluminum rack
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
(separate P and C buses)
• Can also be used as an expansion unit
• For holding up to 18 modules
• Also available as aluminum rack
ER1 (Extension Rack)
• For setting up expansion units economically
• For holding up to 18 modules with restricted functionality
• Also suitable for S7-400H
• Also available as aluminum rack
ER2 (Extension Rack)
• For setting up expansion units economically
• For holding up to 9 modules with restricted functionality
• Also suitable for S7-400H
• Also available as aluminum rack
