User Interface Section 2 Functional Description28 9ARD000014-600 AUser InterfaceThis section describes the user interface for the protocol, such as hardware units andtheir configuration parameters, status, alarms, and events.Hardware TreeThe Hardware Tree is a hierarchical representation of information in the ControlBuilder. The configuration of the controller, the Communication interfaces and thedevices and I/O modules under it is specified in the hardware tree. Configurationinformation is provided at each level in the hardware tree.Figure 4 shows the typical hardware tree for CI873, depicting the DeviceNet andEtherNet/IP device unit types imported into hardware library using EDS files. TheCI873 represents an EtherNet/IP I/O scanner which originates the CIP connections.All the devices configured under CI873 represent targets to which the I/O scannerestablishes the connections. Each device is represented with one hardware unitwhich contains the configuration related parameters to be downloaded to the device.The hardware unit also contains connection related parameters to establishconnections to the device, and I/O channels to view the I/O data.The CI873EthernetIPHWLib contains the hardware units for CI873, CI873 ScannerDiagnostics, LD 800DN linking device, and LD 800DN diagnostics.
