■ Overview
Expansion units can be used for the distributed expansion of the
SIMATIC S7-400. The IM 460-x interface modules are used as
the interface for these expansion units.
Restrictions compared to standard I/O modules from the
ET 200M range
• No redundant interfacing of expansion units
• No configuration during normal operation
Subracks
The universal racks (UR) are used for SIMATIC PCS 7. They can
be used as central racks and as expansion racks. Other racks:
see Catalog ST 70.

IM 460-0 interface module
• Transmitter module for central
controller
• Without transmission of voltage
to the expansion unit
• Cable up to 5 m long
• With K-bus for communication
with CPs and FMs in the expan-
sion unit
• For connecting as many as 8 ex-
pansion units
