Create Sampled Value Control Blocks

Open create wizard

To access the Sampled Value Control Block, follow these steps:

1. Navigate to the Substation editor.
2. Click on the S icon button in the upper Right corner.
3. Click on Sampled Value Control Block +.
4. Select the IED where you want to store the Sampled Value Control Block.

Alternatively:

1. Navigate to the Substation editor.
2. Click on one of the IEDs in the editor.
3. Click on the S action icon.
4. Click on Sampled Value Control Block+.

NOTE: The SampledValueControl element, its child elements, and its referenced DataSet element are saved to the first LN0 element in the selected IED.

NOTE: The SMV can only exist if the access point (ConnectedAP) of the server is connected to a sub-network (SubNetwork) in the Communication section.

 

This create wizard consists of several pages. All pages must be completed correctly to add the Sampled Value Control Block and its DataSet to the SCL. You can navigate between the pages using the buttons in the footer.

NOTE: The Save button, which adds the GOOSE Control Block to the SCL, is on the last page.

 

SampledValueControl page

This page contains a set of settings the server needs to have to be able to generate a SampledValueControl:

• name: The main identifier for the Sampled Value within the SCL. It must be unique for all SampledValueControl elements in the same parent element and influences the Sampled Value Control Block reference.
• desc: An optional string describing the SampledValueControl element.
• multicast: Only visible when false, as non-multicast sampled value streams are deprecated.
• smvID: A unique identifier for the Sampled Value.
• smpMod: The mode in which the sample rate is expressed. Options include Samples per period, sampled per second, or Seconds per sampled. The default is Samples per period
• smpRate: The sample rate, dependent on the sample mode.
• noASDU: Timestamps per Ethernet packet.
• securityEnabled: Specifies the type of security measures the Sampled Value has: encryption and/or signature, or none of the two.

 

Adding the Optional information page

This wizard enables the configuration of optional behaviors for the sampled value stream.

1. refreshTime: Specifies whether the timestamp of the generation of the sample value stream shall be included.
2. sampleRate: Determines whether the sample rate and sample mode shall be part of the sampled value stream.
3. dataSet: Specifies whether the data set reference shall be part of the sampled value stream.
4. security: Determines whether the sampled value stream contains the security attribute (Used for future definitions such as digital signature).
5. synchSourceId: Specifies whether the the sampled value stream contains the synchronizing grand master ID.

Communication page

This wizard allows you to define all communication-related settings for the Sampled Value. This information is saved in the Communication section, more precisely in the element SMV.

1. MAC-Address: Specifies the destination MAC address of the Sampled Value, ranging from 01-0C-CD-04-00-00 to 01-0C-CD-04-01-FF.
2. APPID: Sets the APPID of the Sampled Value, and it is recommended to be unique throughout the entire project.
3. VLAN-ID: Determines the virtual LAN ID to which the Sampled Value shall be limited.
4. VLAN-PRIORITY: Sets the priority of the Sampled Value message, allowing prioritization of time-critical messages like trip signals over non-time-critical messages.

Data picker

To define the data set, a multi-select data picker is used on the last page of the create wizard. This allows you to select multiple data attributes at the same time. The example below picked the data attributes instMag and its quality information q from the data object AmpSv, the logical node TCTR 1, and the logical device PowS_MeasPointI3ph1.
