Control Point Data Types
IEC 61850 defines many controllable data classes, Geo SCADA Expert encapsulates them all as Analog or Digital Control points. The table below shows the mapping of IEC 61850 Data Class and Data Type to MMS Data Type and the type of control used.
| Data Class | IEC 61850 Data Type | MMS Data Type | Control Type |
|---|---|---|---|
| Controllable single point (SPC) | BOOLEAN | Boolean | Digital |
| Controllable double point (DPC) | BOOLEAN | Boolean | Digital |
| Controllable integer status (INC) | INT32 | Integer | Analog |
| Controllable enumerated status (ENC) | ENUM | Integer | Analog |
| Binary controlled step position information (BSC) | CODED ENUM | Bit-string | Analog |
| Integer controlled step position information (ISC) | INT8 | Integer | Analog |
| Controllable analogue process value (APC) | {INT32;FLOAT32;} | {Integer;Unsigned;} | Analog |
| Binary controlled analog process value (BAC) | CODED ENUM | Bit-string | Analog |
