Ethernet/IP physical devices, their logical devices, and device signals are configured under the port.
Ethernet/IP physical device configuration consists of specifying the physical device's primary and secondary IP addresses.
Ethernet/IP logical devices are groups of functions for the physical device. Ethernet/IP logical device configuration in DeltaV Explorer involves defining the characteristics of the device data represented by the logical device. Among the items configured in a logical device that uses the Ethernet/IP protocol is the messaging class (Class 1 Implicit, Class 3 Explicit, Class 3 with PCCC, and UCMM with Logix Tags), and the input and output sizes. Refer to the device documentation for the specific values to use to configure the logical device and to the context sensitive help in DeltaV Explorer.
The device signals are used to access the device data. Many Ethernet/IP signal values are populated with information from the logical device.
To reduce the risk of I/O output failures and output transfer failures when using the EtherNet/IP protocol, Emerson recommends configuring one module to write to all output signals configured within a single LDT.
The Use Device Extended Address option on the EIOC or PK controller local device properties dialog enables you to route messaging to a ControlLogix CPU that is installed in a chassis that is remote from the ControlLogix Ethernet card to which the EIOC connects. Messaging requires a route through the various cards, ports and backplanes that represent the data flow from the entry point to the point where the data resides. This is done through numeric values that represent ControlLogix device components.
The table describes how the components in a ControlLogix device map to the DeltaV configuration. DeltaV Explorer help provides more information on the dialog fields.
