IEC 61850 (legacy) | Connections
Once configured, the IEC 61850 I/O interface offers different data points for each configured message to be connected with the model using the HYPERSIM sensors.
GOOSE (8-1) Publishers
Connection point | Direction | Description |
|---|---|---|
| Enable | From model to driver | Controls the transmission of GOOSE message. An input of 1 activates transmission and value of 0 disables it. |
| Data / Data Objects (DO) / Data Attributes (DA): | From model to driver | Every basic attributes found in the GOOSE definition provides a connection point referenced by their DO and DA names. |
| Flags | From model to driver | simulation: This input controls directly the GOOSE Header field "test". If input value is TRUE, GOOSE message will be transmitted with test flag equal to TRUE informing to all subscribers that Object Input Data is the result of a testing. ndsCom: This input controls directly the GOOSE Header field "needs commissioning". |
| Clock | From model to driver | Sync: It is a binary value (0 or 1) that represents the synchronization state of the timestamp. If the timestamp is synchronized with an accurate external source such as a GPS, the value applied to this signal should be set 1 and otherwise it should be 0. This value will appear in each time qualify byte of the data frames to indicate the validity of the timestamp. Epoch: Represents the number of seconds elapsed since first January 1970, commonly known as unix epoch time. It means that it has to increment at each second. The GOOSE Publisher uses this signal to timestamp the outgoing packets. The more accurate this epoch time input will be, the more accurate will be the timestamp of the outgoing packets. Microseconds: Represents the microseconds count within the current second. |
| Status | From driver to model | stNum: This value is incremented, starting from 0, with every change of whichever of the objects contained within the GOOSE message. sqNum: This value is incremented, starting from 0, with every GOOSE message received without any modification to its objects' value. If any change is detected for whichever of the objects this count is RESET to zero. |
GOOSE (8-1) Subscribers
Connection point | Direction | Description |
|---|---|---|
| Enable | From driver to model | Controls the reception of GOOSE message. An input of 1 activates reception and value of 0 disables it. |
| Data / Data Objects (DO) / Data Attributes (DA): | From driver to model | Every basic attribute found in the GOOSE definition provides a connection point referenced by their DO and DA names. |
| Status | From driver to model | stNum: This value is incremented, starting from 0, with every change of whichever of the objects contained within the GOOSE message. sqNum: This value is incremented, starting from 0, with every GOOSE message received without any modification to its objects' value. If any change is detected for whichever of the objects this count is RESET to zero. State:

Sampled Values (9-2LE) Publishers
Connection point | Direction | Description |
|---|---|---|
| Enable | From model to driver | Controls the transmission of Sampled Values message. An input of 1 activates transmission and value of 0 disables it. |
| Voltage Value | Vector of 4 voltages [Va, Vb, Vc, Vn] which are the 3 phase voltages and neutral voltage. | |
| Voltage Quality | Vector of 4 quality values [QVa, QVb, QVc, QVn]. Each element represents a 16-bit value. The signification of each bit is described in the table below. | |
| Current Value | Vector of 4 currents [Ia, Ib, Ic, In] which are the 3 phase currents and neutral current. | |
| Current Quality | Vector of 4 quality values [QIa, QIb, QIc, QIn]. Each element represents a 16-bit value. The signification of each bit is described in the table below. | |
| Clock | Ideally, the timestamp input should come from an accurate synchronization source. Otherwise, there is no guarantee on the data sampling, reported data rate and fraction of second information. Sync: It is a binary value (0 or 1) that represents the synchronization state of the timestamp. If the timestamp is synchronized with an accurate external source such as a GPS, the value applied to this signal should be set 1 and otherwise it should be 0. This value will appear in the "smpSynch" attribute of SV messages. Seconds: Represents the second increment, which may be the epoch time (see above), as well as a counter of a period of one second. It means that it has to increment at each second. The Sampled Values Publisher uses this value to set the attribute "smpCnt" in SV messages. The more accurate this epoch time input will be, the more accurate will be the timestamp of the outgoing packets. |

Data Integrity Manipulation
When Sampled Values Data Integrity Manipulation is enabled, additional connection points are available to manipulate Sampled Values (9-2LE) Publisher messages.
Every Sampled Values (9-2LE) Publisher message will have a new connection group called "Faults" with the new connections points. Here is a short description of the different faults, and how to configure them. For more information, look at the component that was specifically designed to use this feature here.
Loss
Simulate the loss of packets on the network by stopping the SV publishing during a certain amount of frames. If monitored, the stream will appear as it loses n packets of data.
| Connection point | Direction | Description |
|---|---|---|
| Trigger | From model to driver | At rising-edge from 0 to 1, the fault will be applied. Trigger needs to be reset at 0 to be able to create a new fault. |
| Mode | From model to driver | 0 → Fault is applied immediately after trigger is raised. 1 → Fault is applied as soon as the smpCnt reaches the value provided in the connection "Wait for smpCnt". |
| Number of frames | From model to driver | This value is the number of frames that will be dropped, prevented from being sent on the network. |
| Wait for smpCnt | From model to driver | If "Mode" is set to 1, the fault is delayed to wait the specified smpCnt value. |
Duplication
Simulate a wrong network topology where packets could be sent multiple times by duplicating frames a certain time and for a certain amount of frames.
| Connection point | Direction | Description |
|---|---|---|
| Trigger | From model to driver | At rising-edge from 0 to 1, the fault will be applied. Trigger needs to be reset at 0 to be able to create a new fault. |
| Mode | From model to driver | 0 → Fault is applied immediately after trigger is raised. 1 → Fault is applied as soon as the smpCnt reaches the value provided in the connection "Wait for smpCnt". |
| Number of frames | From model to driver | This value is the number of frames on which the duplication fault will be applied. |

An internal buffer will keep all the information to delay the packet. The delay can be a value from 0 to 1,000,000, i.e. the maximum accepted delay is one second. |
| Wait for smpCnt | From model to driver | If "Mode" is set to 1, the fault is delayed to wait the specified smpCnt value. |
