IntelliCENTER EtherNet/IP MCC System Architecture
24V DC Power
Chapter 2
24V DC power is integrated throughout the IntelliCENTER EtherNet/IP
MCC and is supplied by 24V DC power supplies that reside in plug-in MCC
units. Optional redundant 24V DC power supply configurations are also
available. The integrated 24V DC power provides ease of use connections for all
IMC devices with EtherNet/IP communication options that require 24V DC
power and the Stratix 5700 switches. For information on the 24V DC power
connections, see EtherNet/IP Network and 24V DC Connections.
The number of 24V DC power supplies required throughout the
IntelliCENTER EtherNet/IP MCC is dependant upon the number of Ethernet
switches and IMC EtherNet/IP communication devices that require 24V DC
power. For more information on the 24V DC power configuration and layout,
see the CENTERLINE Motor Control Center with EtherNet/IP Network
Technical Data, publications 2100-TD031 and 2500-TD003.
EtherNet/IP Network and
24V DC Connections
The IntelliCENTER EtherNet/IP MCC design uses the best practices from the
IntelliCENTER DeviceNet MCC design but adds the flexibility and
performance of an EtherNet/IP network. These design methods deliver a fast
and reliable industrial network for the IntelliCENTER EtherNet/IP MCC.
EtherNet/IP Network and 24V DC Connections within a Shipping Split
CENTERLINE IntelliCENTER MCCs ship configured from the factory in
shipping splits that typically consist of one, two, or three MCC sections. Because
the shipping split ships as a continuous block of MCC sections, all EtherNet/IP
and 24V DC power connections for IMC devices within the shipping split are
prewired at the factory. The connections include all Ethernet switch-to-IMC
device connections and all 24V DC power connections for IMC devices.
Additionally, Ethernet switch-to-switch connections within an MCC shipping
split are also prewired at the factory. For information on connections across
MCC shipping splits that are not prewired at the factory, see the EtherNet/IP
Network and 24V DC Connections Across Shipping Splits section.
