FEP Status
The FEP Status pane contains a table that shows the current state of all Front End Processors (FEPs) configured in the system. Each row in the FEP monitor list shows information about a FEP and a specific connection configured for that FEP. Therefore, if a FEP has multiple configured connections then that FEP may show up in the list multiple times, once for each connection. Only one FEP row can be selected at a time; when a FEP is selected, a right click context menu allows you to choose from the available actions to be performed on that FEP. The context menu will only show the actions valid for the current state of the FEP; for example, if the FEP is in the enabled state, then the Enable FEP option will not be available.
FEP Status List Banner
The FEP Status List banner situated above the Status List gives a summary of the state of the FEPs in the list and allows quick filtering. The banner consists of a label and count for each state a FEP can be in. The count is an indication of the number of FEPs in the list that match that state.
The available states are:
• Enabled: A count of the number of FEPs enabled for scanning.
• Disabled: A count of the number of FEPs currently shut down.
• Failed: A count of the number of FEPs that are currently deemed to be in a failed state due to communication issues.
Selecting any label or count in the banner will filter out that state from the FEP Status List. The label in the banner will be highlighted and the states count will be struck through to indicate that FEPs in that state have been filtered out of the Status List.
Reselecting the label or count in the banner will restore all FEPs in that state back into the FEP Status List, they will no longer be filtered out. The label will no longer be highlighted and the count will no longer be struck through.
Context Menu Options
Depending on what you select, you may have the following options.
• FEP Details: Open the FEP Details tool allowing edit of the configurable FEP options.
• Show IEDs for the Selected FEP: Opens the IED Monitor filtered to only display IEDs that are configured for the selected FEP.
• Enable FEP: Enables the selected FEP.
• Disable FEP: Disables the selected FEP.
• Change Active Connection: Changes the communications channel used to communicate to the FEP. Only visible if the FEP has multiple channels configured.
• Reset FEP Statistics: Resets the communication statistics for the selected FEP.
• Reset All IED Statistics: Resets the communication statistics for all IEDs configured on the selected FEP.
• Enable Debug: Enables the logging of debug messages for the selected FEP.
• Disable Debug: Disables the logging of debug messages for the selected FEP.
• Synchronize: Resynchronizes the FEP configuration to the FEP itself.
• Delete FEP: Deletes the FEP. This action will only complete if the FEP has no IEDs configured.
FEP Connection Options
The FEP Connection context menu provides the following options.
• Enable Connection: Enables the selected FEP connection.
• Disable Connection: Disables the selected FEP connection.
• Change Active Connection: Changes the communications channel used to communicate to the FEP. Only visible if the FEP has multiple channels configured.
Point Monitor
The point monitor is a point list that can be used to display the current value and quality of input points from any IED or combination of IEDs. Using the option on the right-click context menu of the IED input tool the user can choose the 'Add to point Monitor' option to add the selected points to the point monitor list. This list is common for all points and so does not contain any protocol specific columns. The context menu on the point monitor row allows the user to position on the relevant component in the diagram, or to remove the point from the point monitor list.
