Detailed Description

The value of a datapoint.

It is used to publish data and also to receive data from the core via subscription or trough the RealtimeDatabase.

Field Documentation

◆ b

bool sGCDatapointValue::b

◆ datapoint_id

GCDatapointIdentifier sGCDatapointValue::datapoint_id

The identifier for the datapoint.

Each datapoint has it's own datapoint identifier, this is used to identify the datapoint in the system. This can be retrieved from the datapoint configuration.

◆ dp

uint8_t sGCDatapointValue::dp

◆ f32

float sGCDatapointValue::f32

◆ f64

double sGCDatapointValue::f64

◆ i32

int32_t sGCDatapointValue::i32

◆ i64

int64_t sGCDatapointValue::i64

◆ quality

GCDatapointValueQuality sGCDatapointValue::quality

Represents the quality of the datapoint value.

This is a bit field mimicking the same structure as the one used in IEC-61850-8-1 for quality.

See also: IEC-61850-8-1

◆ timestamp

uint64_t sGCDatapointValue::timestamp

The timestamp when the value was generated in nanoseconds since the Unix epoch.

◆ timestampNs

uint64_t sGCDatapointValue::timestampNs

◆ type

GCDatapointValueType sGCDatapointValue::type

The type of the datapoint value This type depends on the datapoint's value field.

◆ u32

uint32_t sGCDatapointValue::u32

◆ u64

uint64_t sGCDatapointValue::u64

◆ [union]

union { ... } sGCDatapointValue::value

The value of the datapoint.
