User Interface
This section describes the user interface for the protocol, such as hardware units and
their configuration parameters, status, alarms, and events.
Hardware Tree
The Hardware Tree is a hierarchical representation of information in the Control
Builder. The configuration of the controller, the Communication interfaces and the
devices and I/O modules under it is specified in the hardware tree. Configuration
information is provided at each level in the hardware tree.
Figure 4 shows the typical hardware tree for CI873, depicting the DeviceNet and
EtherNet/IP device unit types imported into hardware library using EDS files. The
CI873 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 scanner
establishes the connections. Each device is represented with one hardware unit
which contains the configuration related parameters to be downloaded to the device.
The hardware unit also contains connection related parameters to establish
connections to the device, and I/O channels to view the I/O data.
The CI873EthernetIPHWLib contains the hardware units for CI873, CI873 Scanner
Diagnostics, LD 800DN linking device, and LD 800DN diagnostics.
