Object table

Command object

The data object used for the control action, e.g. CSWI4.

Controlled object

The object, controlled by the selected command object, e.g. XCBR1.

Test

Shows if the test flag is set for operations of this object.

State

Shows if the object can be operated. If not, a warning is displayed ().

Buttons

...Add a new object to the list, see Command configuration dialog below.

...Modify the selected object, see Command configuration dialog below.

...Remove the selected object

...Remove all objects

Command Configuration Dialog

The dialog allows to add or modify an object from the object table.

Figure 2. Command configuration dialog

IED

The IED preselected within the basic device configuration of the IEC 61850 engineering.

Command object

The command object can be selected from within the "IEC 61850/61400 address tree" panel by pressing the "..." button.

Controlled object

As with the command object the controlled object can also be selected from within the "IEC 61850/61400 address tree" panel by pressing the "..." button. The available entries within the address tree of controlled objects are already filtered and only display the available elements for the previously selected command object.

Please note that selecting the Command/Controlled object can only be done when adding a new entry to the configured objects table. Command/Controlled objects cannot be updated afterwards. To change these settings a new object must be configured.

RCB

Allows to select a Report control block that should be used. Using the "..." button the "RCB selection" dialog is opened. Within the dialog the RCB used for the controlled object can be selected.

Check

Defines the check conditions. Possible values are:

No check
Synchro check
Interlocking check
Both

Test

Defines if the sending of the command should be tested.

Selected object details

Command object

The object selected in the table of configured objects (above).

Control model

The control model which shall be used. It is automatically set after selecting the command and the controlled object according to the settings read from the data source used for configuration.

The current Configuration data source can be seen in the top right corner of the Engineering panel.

Following control model types are available:

Status-only
Direct operation with normal security
Select before operate with normal security
Direct operate with enhanced security
Select before operate with enhanced security

The combo box also allows to change the control model online if changing the control model is allowed for the selected command object.

Controlled object

The object, controlled by the selected command object

Report control block

The report control block configured for the selected object.

Send command

The area allows to send a command for the selected object.

Current value

The current value of the monitored data attribute of the controlled object.

New value

The control value to be sent. The "Set value" button opens a new dialog in which the command must be verified, see Operate Panel description below.

Operate

Depending on the data type of the monitored data attribute of the controlled object the button displays either Set (data type BOOL) or Operate (other data types like INT, FLOAT). Click this button to open the Operate panel.

Warning Symbol

If the selected object cannot be operated a warning symbol () is shown.

Possible issues are, that no RCB has been configured or the RCB is not enabled. To see what causes the issue you can position your cursor on top of the icon and get a state summary for the configured object, indicating what additional configuration is required.

Response

Shows the response to a sent command. The response might be either an error code or a confirmation in case of success. Possible responses are listed in tables "IEC 61850 control model error codes" and "IEC 61850 control model response codes" on Details of IEC 61850 control model

Add cause

Provides additional information if one of the enhanced modes (DOe or SBOe) is used. Possible values are listed in table "AddCause values" on Details of IEC 61850 control model.

Operate Panel

This panel is used to confirm, i.e. send the command. It shows the command to be sent (new value, check and test conditions, none of these changeable here), provides the buttons for operations and shows the response after sending the command.
