Overview of IEC61850 protocol for MindConnect Software Agent¶
IEC61850 defines an architecture to meet the needs of electrical substation automation. It defines a data model and the communication services for the interaction with and between the elements of a substation such as feeders, breakers, protection devices, etc.
The following image shows the data source input window for the IEC61850 protocol:
In order to connect a IEC61850 device, you need to select the IEC61850 protocol and enter the following data source parameters:
| Parameter | Description |
|---|---|
| SCD File | Choose a valid SCD file. It contains the connection details (IP address, server name, access point) and the data (logical nodes, data types, data points, …). The SCD File must have a valid extension: *.xml, *.zip, *.tgz, *.tar.gz. |
| Server Name | Name of the Intelligent Electronic Devices (IED) must match to the SCD file. |
| Access point name | Name of the access point must match to the SCD file. |
Note
- The IED name within the SCD file must be set to “Industrial IoT Client” or to the serial number of the device.
- Server Name and Access point must match with the data in the SCD file. It is necessary for a double check of the configuration.
IEC61850 data point parameter¶
In order to collect the data of the IEC61850 device, click "Add Datapoint" to add new datapoint.
The following picture shows the data point parameter window:
The following table shows the parameter of the IEC61850 data point window:
| Parameter | Description |
|---|---|
| Datapoint Address | The browse string, as defined in the SCD file. Example: MSC_SRV01CTRL/ATCC1$ST$HiTapPos$stVal |
| Type | The following datapoint types are supported: int, long, double, boolean, string |
| Type Transformation | For the above datatypes, the following transformation types are available (see also table below): - int: INT8, INT16, INT32, INT64, UINT8, UINT16, UINT32; - long: INT8, INT16, INT32, INT64, UINT8, UINT16, UINT32, BITSTRING, TIMESTAMP; - double: FLOAT32, FLOAT64, INT32, INT64, UINT8, UINT16, UINT32, BITSTRING, TIMESTAMP; - boolean: BOOL; - string: OCTET_STRING64, VISIBLE_STRING64, VISIBLE_STRING255, TIMESTAMP |
| Data Acquisition Mode | The following modes are supported: READ (spontaneous / reports), WRITE READ and WRITE |
