Overview of IEC61850 protocol for MindConnect IoT2050¶
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¶
The following image 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 |
