Shows the arrangement of nodes (DeltaV Controllers and DeltaV workstations) and subsystems (CommunicationsI/O cardsControlAlarms and Events, and so on) in your Control Network. Typically, controllers have CommunicationsI/O, and Control subsystems and DeltaV workstations have CommunicationsAlarms and EventsProcess History subsystems. To explore the hierarchy for a node or subsystem, click the plus sign (+) next to the node or subsystem. Continue to click the plus signs until you find the node or subsystem you are interested in. To see diagnostic information about a specific node or subsystem, click it. The Diagnostics program displays the information in the Parameters columns. A minus sign (-) next to a node or subsystem in the hierarchy means that that level is completely expanded.
Visual Indicators
Visual indicators are used to represent the status of nodes and subsystems. The indicators appear both at the top level in the hierarchy and at the specific node or subsystem. Note The absence of any of the following indicators means that the node integrity is good:
|
Indicates that the Diagnostics program does not have all the information on the node with this indicator. For example, if an unconfigured I/O card is pulled, this indicator appears. To clear this indicator, select the node, and then click . |
|
|
Indicates that the node is not communicating. Typically this indicator occurs when there is a bad connection, or if the node is not powered up or is decommissioned. To clear this indicator, verify that the node is connected, that the wiring is correct and sound, and that the node is powered up. |
|
|
Indicates that the node has lost its configuration or the configuration was not downloaded. A node can lose its configuration if it loses power or is reset. To clear this indicator download the configuration to the controller or workstation. |
|
|
Indicates that the node is communicating but has an integrity problem. Integrity problems can occur for a variety of conditions including hardware or connection problems, a mismatch between the I/O configuration and the installed I/O, or if the node is configured for network redundancy but does not have the necessary connections to support it. To clear this indicator, correct the problem at the node or subsystem that is displaying this indicator. |
|
|
Indicates that the integrity of one or more of the Logic Solvers on the controller's subsystem is Bad. This indicator has a higher priority than the Integrity indicator, but not as high as the Not communicating indicator. |
