Status indicators

Node status indicators

Incomplete information

For nodes, this indicates that the downloading node (the workstation) does not have all the information on the node with this indicator. To clear this indicator, right-click the node with the indicator, and then click Download Setup Data. This transfers setup data from the database to the physical node. It also updates the downloading workstation node so that the workstation has all the information it needs to manage the new node. This indicator can appear on controllers and workstations that are physically connected to the network or on controller or workstation placeholders. Note that you cannot download the system data for a placeholder because the physical node must be connected first.

For devices, this indicates that the device is not commissioned. To commission the device, select it from the Decommissioned Fieldbus Devices list and drag it to either a port or device placeholder.

Integrity

Indicates that the node is communicating but has an integrity problem.

Controllers can have this indicator for several reasons. For example:

• There is a mismatch between the I/O configuration and the physical I/O. Compare the controller’s I/O configuration in the Explorer with the actual I/O cards connected to the controller.
• The controller is configured for network redundancy but does not have the necessary connections to support it. Check to see if the node is configured to support network redundancy. If it is, make sure the controller has a network connection.
• Some modules may not be executing at their configured scan rate (slippage is occurring). This is indicated in Diagnostics by an MpctOnTime value of less than 100.

Workstations can have this indicator for several reasons. For example:

• The workstation is configured for network redundancy but does not have the necessary connections to support it. Check to see if the workstation is configured to support network redundancy. If it is, make sure the workstation has a network connection.
• The workstation cannot communicate with at least one controller that it needs to communicate with.
• The Event Chronicle database has detected an error (such as an invalid directory).

Locked

Indicates that the node is locked (the node's LOCKED parameter = TRUE). A locked node cannot be downloaded (full or partial); cannot be decommissioned; cannot be upgraded; cannot have its maintenance port's privileged menus accessed.

SIL Integrity

Indicates a problem with the overall integrity of one or more of the logic solvers or SISNet repeaters connected to this controller (the SInteg parameter is not GOOD). This indicator has a higher priority than the Integrity indicator, but not as high as the Not communicating indicator.

No configuration

Indicates that the node does not have a configuration. This can occur if the node has never been downloaded. For controllers, this can occur if there is a power failure and cold restart was not enabled for the node.

Not communicating

Indicates that the node is not communicating. This indicator occurs when there is a bad connection, if the controller is not powered up, or if the controller is decommissioned. To clear this indicator, go to the node and make sure it is connected, that the wiring is correct and sound, and that the node is powered up.

The Explorer enables you to launch the Diagnostics application and view diagnostics data for any selected Explorer object. This can provide useful diagnostic information for nodes that have the indicator. To investigate integrity problems for a node, right-click its icon, and then select Diagnose.

Download status indicators

Needs downloading

Indicates that some of the parameters in the database for this object do not match the parameters in the node itself. The Needs Downloading column in the right-pane detailed view displays a value of Yes. To open the Pending Download Changes dialog, containing a list of all modified download scripts contributing to the pending download of a selected item, right-click the node, and then select Download Status → Show Details.

Unknown

indicates that some of the parameters in the database for this object might not match the parameters in the node itself. The Needs Downloading column in the right-pane detailed view displays a value of Unknown. To determine if a download is required, right-click the node, and then select one of the following menu options:

• Download Status → Update

  If a blue triangle () status indicator appears for this node, a download is required.

• Download Status → Show Details

  After updating the download status for the node, the Pending Download Changes dialog opens. If a blue triangle () status indicator appears for this node, a download is required.

Module indicators

Library module

Represents a library module. You can drag library modules into an area, modify them, and use them in your configuration strategy.

Area module

Represents a module in an area. A module in an area is the database copy of the module. Area modules can be edited and assigned by reference to a specific controller.

Module assigned to a controller

Represents a module assigned to a controller. The control associated with this module will be placed in the controller when the controller is downloaded.

Module assigned to a controller and downloaded

Represents a module that has been assigned to a controller and downloaded.

Module downloaded in a controller (assignment deleted)

Represents a downloaded module for which the assignment has been removed.

SIS Module Indicators

SIS Library module

Represents an SIS library module. You can drag library modules into an area, modify them, and use them in your configuration strategy.

Area SIS module

Represents an SIS module in an area. A module in an area is the database copy of the module. Area modules can be edited and assigned by reference to a specific controller.

SIS Module assigned to a Logic Solver

Represents an SIS module assigned to a Logic Solver. The logic defined by this module will be placed in the Logic Solver card when the Logic Solver is downloaded.

SIS Module assigned to a Logic Solver and downloaded

Represents an SIS module that has been assigned to a Logic Solver and downloaded.

SIS Module downloaded to a Logic Solver (assignment deleted)

Represents an SIS downloaded module for which the assignment has been removed.
