Properties¶
: In the Properties section of the Configuration tab the following functions can be performed dependent on the marked object or the marked instance:
Note
If you move the mouse pointer over an input field or the name of an input field, you get a tooltip with a description in the window below the Properties (see the following figure).
Parametrization of the IEC 61850 Server
‘Properties’ with tooltip of ‘Max. client count’
| Property | Description |
|---|---|
| Server Name | Name of the server, |
| IP I Subnetmask I Gateway | Own IED IP address, I Subnetmask I own gateway address |
| Max.client count | The maximum number of clients that can connect to the IED, possible values: 1, 2, 3, 4, 5 |
| Allowed IPs | Allowed IPs for clients 1…5 default is 0.0.0.0, whereby an IP address that equals 0.0.0.0 means that no IP address validity test will take place. If more than one client connection was selected above, additional IPs must be configured for each one. As soon as an IP address is parameterized with 0.0.0.0, testing for all connected clients is deactivated. |
| Time synchronisation | Selection: SNTP SNTP (default): SNTP time synchronization. In addition to activation, functionality must be parameterized in the device’s web-based management. Currently, the SNTP time telegram does not use milliseconds, which means accuracy is measured in 1 second increments. 1. Input field Time zone: Offset between Greenwich (GMT)- and the local time (for Germany 1 h, for example). The value is limited between -12 an d+ 14 2. Input field: DLS Mode: Ratio for the mode summer/winter time changeover. Possible values:
|
| Task Prio I Interval | Task 1.input field: entry of the priority, 2.input field: entry of the interval in ms |
| TCP KeepAlive[sec] | The KeepAlive is to check the connection to the client. |
Entry of a device name for the Logical Device
If the Logical Device 
is focused in the configured server you can entry a device name for the Logical Device in the ‘Properties’ section.
Connecting an attribute (DA) with a CODESYS variable
Select the attribute of a CDC instance below the server.
Enter the desired CODESYS variable name into the input field Monitoring Var in the properties section.
Entry optionally an initial value into the input field right-side hand of the variable name.
In case of an attribute with RW-access, a Control Variable (writing access) can be entered in addition to the Monitoring Var variable (reading access) . For a more detailed description about reading and writing of variables at the IEC 61850 Server see Reading and Writing from CODESYS Variables. The monitoring and control variables declared in the Properties section are displayed next to the respective attribute and at the superordinated node DO of the server tree.
By activating the Autom. declare checkbox the variable is declared by the IEC 61850 configurator and stored in the IEC61850_Generated_GVL (of the IEC61850 Generated POUs folder) after Generate code of the IEC 61850 Server.
Note
If you do not activate the Autom. declare checkbox you select the variable via the input assistance (F2)) or you declare the variable yourself.
Trigger option: With the trigger options you set the attributes to select the events which might trigger a report. The selected trigger option is displayed in the status bar. For a description of the options see Status bar.
Note
The trigger option determines whether the Report, assigned to the DataSet, is sent when the value of this attribute changes.
‘Properties’ for the attribute(DA) ‘ctlNum’, input fields: ‘Monitoring Var’ with ‘Initvalue’
‘Properties’ of an attribute with RW-access: in addition input : ‘Control Variable’
Entry of a node prefix for LNC instances
‘Properties’ of the LNC instance ‘GGIO1’ with ‘Node prefix’ input field
Here you enter a prefix for the selected LNC instance. The prefix is put in front of the LN name in the server tree. The prefix is displayed in the Status bar, too.
