Installation and maintenance practices for the UOC's downlink
EtherNet/IP network generally follow those described in EtherNet IP
User's Guide_EPDOC-X399-en-510A.pdf for topology 2, "C300
Through EIM To EtherNet/IP". Additional considerations for
components that connect to the EtherNet/IP network are
summarized in the following table. ControlLogix PLCs and
EtherNet/IP I/O and Devices are equivalent to those for DLR ring
networks.
Comments
The UOC CPM connects to a downlink EtherNet/IP network through
its ETH3 and ETH4port. Important properties of UOC CPM
communications on the downlink network are configured on the UOC
Platform Block in Control Builder. This includes configuration of the
UOC DHCP server for assigning EPM IP addresses. It also includes
Downlink Network Configuration to Non-redundant.
When 900 I/O is used, the EPM in the I/O rack serves the role of
communication gateway into the I/O rack. When an EPM is connected
to an EtherNet/IP network, its ETH1 port is connected to the switch
