Actions, Active Group and Synchronization

The left panel will always show a Control Operations node from the protection equipment, which may or may not have a (or ) sign, depending on the circumstances. Selecting this node in the left panel, the right panel displays the following:

- A Group Activation item for requesting and editing the active group.

- A Time Synchronization item for requesting from and sending time to the protection

equipment.

- Occasionally, a subtree in the right panel indicates different user-defined commands.

As you already know, if you define your own commands when generating a configuration, these will appear below the time synchronization.

Generally, the screen will look like this:

As usual, the symbol overlaps other symbols to indicate user-defined; that is, extracted from the configuration.

If you had entered settings before pressing Actions in the left panel, an implicit request for the active group would have occurred.

That is, the retrieved data are placed in Actual Value and in Action.

In any case, you can set the Actual Value for all items by pressing . In the case of the active group, it will be the number of the current active group; for the time synchronization, it will be the protection equipment time; and for commands, it will be the command status.

The right panel will then look something like this:

As you can see, the Actual Value is also entered into Action. The same value is proposed in the Action field for the group and time as is found in the Actual Value field. However, in regard to commands, the present command status is found in Actual Value, while in Action we find one of the potential actions, taking the command status into account.

As with the settings, you can edit the different Action values one by one in order to send them to the IED:

- For the active group you can select any of the possible options, bearing in mind the total number of groups.

- The Action field cannot be edited for time synchronization.

The PC's time is taken when sending to the IED. - For commands,

you can choose between actions that are

compatible with the Actual value.

As you can see in the screen, the current value is ON and the possible action proposed is TURN OFF LED 1. Clicking on Action displays all the possible actions for the current value.

Another possible situation for this same example is shown in the screen at right.

Unlike the settings, in this case the data are sent to the protection equipment one by one, by pressing the relevant Execute button.

In all cases except synchronization, the Zivercomplus® program shows the action to be performed, like in the example at right.

If the user presses OK, the action is carried out and the IED indicates whether the action is accepted or rejected.

2.2.7 Records

In the left panel, open up the Records

node to see the four types of records contained in it: Events, Faults, Metering Logs and Oscillographs.

All records have in common that they are labeled by date and are displayed in lists where the natural order is by date, although you can order them according to your own criteria.

The operations that can be performed with them are fairly common: issuing a request, ordering according to different criteria, saving to disk, printing and deleting. Moreover, all the lists allow multiple item selection, so you can apply the operations listed above to the items of your choice. The way the different types of records are handled is described below.

2.2.7.a Events

If no event has been retrieved earlier, pressing on the Events node in the left panel will result in a screen similar to the one below.

The events list will be empty and the Zivercomplus® program will indicate this by the prompt No events to

display.

You can Request

Events from the

protection equipment by pressing . In this case, the Zivercomplus® program lets you specify which events you want.

The available options will shown to be selected (see the righ screen). Starting Date and Ending

Date will be editables only when the Record

option selection is Between Dates. The current date is provided as the default for the start and end dates.

The events retrieval process begins when you press OK. The progress bar at the bottom provides a running account of how many events have been retrieved.

Once the events have been received, and assuming you have pressed to hide the left panel, the screen will look like this.

The top bar indicates that you have retrieved 198 events (items). The meaning of each of the list's fields is important:

- indicates if the event is saved to a drive. There are no saved events in the screen represented as an example.

- indicates the event date and time (down to ms). The triangle indicates that the list is ordered in ascending order according to that field: the oldest events first;

- shows the text associated with the event.

- The , , etc. fields indicate the list of measures retrieved in the event, depending on the protection equipment's settings. Units are indicated in parentheses. All the measures included in a listed event are always shown in the top bar. If a certain measure is not retrieved from a specific event, ***** will be displayed in its value field.

The events can be displayed according to different criteria by simply pressing the desired item. If you press on an item by which the order has already been set, the order is reversed. In this example, if you press Event the list will be ordered alphabetically by  Event, and if you press  Event again, it will be ordered again by Event, but in reverse alphabetical order. Valid ordering fields are S, Time and Event (not magnitudes).

You can Delete events by pressing . This calls up the dialog at right, which lets you delete all events or only the selected ones.

You can save the selected events (Selection or All) in XML format by pressing . As always, you are responsible for choosing the file and directory. You can also add or overwrite events to an existing file. You will want to export events to a file so that you can examine them offline in emulation mode (see Emulation).

The button, which in the Zivercomplus® program means import, is disabled in the events screen because it doesn't make sense to load other events from the program while you are viewing the events from a protection. It is included because of its usefulness in emulation mode (see Emulation) to give the same appearance to all screens.

The other operation you can perform is to print the events. The operation is similar to that of settings: by pressing you can select the events to be printed. When OK is pressed, the program calls up the browser and you can see the events in the format provided during the installation of Zivercomplus®.
