Installation and maintenance practices for the UOC's downlink
EtherNet/IP network generally follow those described in (EtherNet IP
User's Guide) 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.
Comments
The UOC CPM connects to a downlink EtherNet/IP network through
its ETH3 and ETH4 ports. 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 ETAP while its ETH2 port is left disconnected. Before it is inserted
into its slot, the 100x rotary switch on the EPM board must be set to
indicate the type of network connectivity in use. This is done by
setting it to position 4. The IP address of the EPM is assigned by the
UOC CPM based on the module number set on the 10X and 1x rotary
switches. These switches must also be set before the EPM is inserted
into its slot.
UOC systems use redundancy boxes called ETAPs for connectivity to
downlink DLR rings. For further information on the use of ETAPs, see
EtherNet IP User's Guide_EPDOC-X399-en-510A.pdf.
UOC can communicate with Rockwell Allen Bradley ControlLogix
PLCs by passing instances of User Defined Types (UDTs). References
to ControLogix data are created in Experion Control Builder with the
aid of tag names provided by the Matrikon Allen Bradley OPC server
or by export of ControlLogix tag names from the Rockwell Allen
Bradley Studio 5000 designer tool. ControlLogix PLCs on a UOC's
downlink EtherNet/IP network must always use static IP address
assignments. For information on the configuration of ControlLogix
communications, see EtherNet IP User's Guide_EPDOC-X399-en-
510A.pdf.
UOC supports a set of EtherNet/IP devices with pre-populated CEE
block types in Experion Control Builder (CB). In addition, CB provides
the Parameter Definition Editor (PDE) tool which allows for the
integration of new EtherNet/IP I/O and devices independent of
Experion release. Although some third party EtherNet/IP devices
support IP address assignment from a network resident DHCP
server, this feature cannot be used when the EtherNet/IP network
