EtherNet/IP Network and 24V DC Connections

This section is for engineers or technicians who are directly involved with the commissioning of the EtherNet/IP
network and 24V DC connections in the IntelliCENTER MCC. Additional information and figures can be found in
the EtherNet/IP Network Topology section, but the standard IntelliCENTER EtherNet/IP MCC design uses a linear/
star EtherNet/IP topology. In this design, the Stratix 5700 switch-to-switch EtherNet/IP connections use a linear
topology, and the IMC device EtherNet/IP connections to the Stratix 5700 switches use a star topology. A switch-level
ring topology is also available and is identical to the linear/star topology, but the Stratix 5700 switch-to-switch
connections use a switch-level ring topology in place of the linear topology. These topologies are implemented
throughout the MCC lineup by using an EtherNet/IP network and 24V DC power. The EtherNet/IP network and
24V DC power requires connections in each MCC section. You also need connections within and across MCC shipping
splits, which consist of one, two, or three MCC sections. This section focuses on the EtherNet/IP network and 24V DC
connections across and within the shipping splits.

EtherNet/IP Network and 24V DC Connections Within a Shipping Split

This section provides detailed instructions for commissioning the EtherNet/IP network and 24V DC power
connections within the shipping splits.
Within an MCC shipping split, the Stratix 5700 switch-to-switch connections are pre-wired at the factory. Additionally,
within an MCC shipping split, the connections from the IMC devices to the EtherNet/IP switch and 24V DC power
supply are prewired at the factory. The connection method of Ethernet cables varies based on customer preference.
Sections with Plug-in Units in an MCC with Vertical Wireway Adapters
The IntelliCENTER EtherNet/IP MCC design can include vertical wireway adapters to connect IMC devices in plug-
in units to the Stratix 5700 switch and integrated 24V DC power supply. IntelliCENTER MCC sections that contain
plug-in units include up to four EtherNet/IP adapters in the vertical wireway, which lets you connect up to eight IMC
devices (each EtherNet/IP adapter contains two RJ45 Ethernet ports). Ethernet adapters are scaled in each section
according to the number of IMC devices requiring connection, so it is possible that not all sections have four Ethernet
adapters. Additionally, two 24V DC power adapters in the vertical wireway provide four 24V DC connections that let
you power up to eight IMC devices (two IMC devices can be wired to each of the four 24V DC power connections).
The EtherNet/IP and 24V DC power adapters are shown in Figure 9.
