tsSE_PricePublishPriceCmdPayload

This structure is used to hold price information to be added to a price list of a Price cluster:

typedef struct {
    uint8               u8UnitOfMeasure;
    uint8               u8PriceTrailingDigitAndPriceTier;
    uint8               u8NumberOfPriceTiersAndRegisterTiers;
    uint8               u8PriceRatio;
    uint8               u8GenerationPriceRatio;
    uint8               u8AlternateCostUnit;
    uint8               u8AlternateCostTrailingDigit;
    uint8               u8NumberOfBlockThresholds;
    uint8               u8PriceControl;
    uint16              u16Currency;
    uint16              u16DurationInMinutes;
    uint32              u32ProviderId;
    uint32              u32IssuerEventId;
    uint32              u32StartTime;
    uint32              u32Price;
    uint32              u32GenerationPrice;
    uint32              u32AlternateCostDelivered;
    tsZCL_OctetString   sRateLabel;
} tsSE_PricePublishPriceCmdPayload;

where:

u8UnitOfMeasure indicates the resource (e.g. electricity) and unit of measure (e.g. kWh) for the pricing (see Section 42.10.3)
u8PriceTrailingDigitAndPriceTier is an 8-bit bitmap indicating the price tier and the number of digits after the decimal point in the price:
- The 4 most significant bits give the number of digits to the right of the decimal point in the price
- The 4 least significant bits give the price tier in the range 1 to 6
u8NumberOfPriceTiersAndRegisterTiers is an 8-bit bitmap indicating the number of price tiers available and the particular tier that the price information in the structure relates to:
- The 4 most significant bits give the number of available price tiers in the range 0 to 6
- The 4 least significant bits give the price tier used in the range 1 to 6
  
  (this value must be less than or equal to the value in the 4 leading bits)
u8PriceRatio (optional) is the ratio of the price quoted in u32Price to the ‘normal’ price offered by the utility company. The actual price ratio should be multiplied by 10 for encoding this field, so that a field value of 0x01 represents 0.1 and 0xFE represents 25.4, while 0xFF indicates that the field is not used
u8GenerationPriceRatio (optional) is the ratio of the price quoted in u32GenerationPrice to the ‘normal’ price offered by the utility company. The actual price ratio should be multiplied by 10 for encoding this field, so that a field value of 0x01 represents 0.1 and 0xFE represents 25.4, while 0xFF is reserved to indicate that the field is not used
u8AlternateCostUnit (optional) is an 8-bit bitmap indicating the unit for the alternative cost in u32AlternateCostDelivered. Currently, the only supported unit is kilograms of CO2, indicated by the value 0x01
u8AlternateCostTrailingDigit (optional) is an 8-bit bitmap in which the 4 most significant bits indicate the number of digits after the decimal point in u32AlternateCostDelivered (the 4 least significant bits are reserved)
u8NumberOfBlockThresholds is reserved for future use (for Block mode)
u8PriceControl is reserved for future use (for Block mode)
u16Currency indicates the currency (e.g. Euro) used for the price - this field should be set to the appropriate value defined by ISO 4217
u16DurationInMinutes indicates the duration, in minutes, for which the price will be valid (0xFFFF indicates that price will remain valid until changed)
u32ProviderId is an identifier for the utility company
u``32IssuerEventId is a unique identifier for the price information - the higher its value, the more recently the price information was issued (a UTC time-stamp could be used in this field)
u``32StartTime indicates the start-time (UTC) for the price, in seconds. The special value 0x00000000 denotes a start-time of ‘now’
u``32Price is the resource price per unit indicated in u8UnitOfMeasure, expressed in the currency indicated in u16Currency, with the position of the decimal point as indicated in u8PriceTrailingDigitAndPriceTie``r
u``32GenerationPrice (optional) is the resource price per unit indicated in u8UnitOfMeasure, expressed in the currency indicated in u16Currency and with the position of the decimal point as indicated in u8PriceTrailingDigitAndPriceTier, for a resource that is generated on the customer premises and supplied to the utility company (e.g. solar-sourced electric power supplied to the national grid). A value of 0xFFFFFFFF indicates that this field is not used
u32AlternateCostDelivered (optional) indicates an alternative cost (per resource consumption unit) which is measured by a means other than monetary - for example, the amount of CO2 emitted per unit of gas consumed This alternative cost is interpreted as specified by u8AlternateCostUnit and u8AlternateCostTrailingDigit
sRateLabel is a string of up to 12 characters containing a label for the price information in the structure

tsSE_PricePublishConversionCmdPayload

This structure is used to hold information to be added to a conversion factor list of a Price cluster:

typedef struct {
    uint32          u32IssuerEventId;
    uint32          u32StartTime;
    uint32          u32ConversionFactor;
    zbmap8          u8ConversionFactorTrailingDigit;
}tsSE_PricePublishConversionCmdPayload;

where:

u32IssuerEventId is a unique identifier for the conversion factor information - the higher the value, the more recently the information was issued
u32StartTime is the start-time of the conversion factor value. This is the time at which the conversion factor value is scheduled to become active
u32ConversionFactor is used only for gas and accounts for the variation in the volume of gas with temperature and pressure (the value is dimensionless)
u8ConversionFactorTrailingDigit is an 8-bit bitmap which indicates the location of the decimal point in the u32ConversionFactor field. The most significant 4 bits indicate the number of digits after the decimal point. The remaining bits are reserved

tsSE_PricePublishCalorificValueCmdPayload

This structure is used to hold information to be added to a calorific value list of the Price cluster:

typedef struct {
    zenum8                u8CalorificValueUnit;
    zbmap8                u8CalorificValueTrailingDigit;
    uint32                u32IssuerEventId;
    uint32                u32StartTime;
    uint32                u32CalorificValue;
}tsSE_PricePublishCalorificValueCmdPayload;

where:

u8CalorificValueUnit is an 8-bit enumerated value which defines the unit for the u32CalorificValue field (below). It indicates whether the calorific value is quantified per unit volume or per unit mass - see Section 40.12.3.
u8CalorificValueTrailingDigit is an 8-bit bitmap which indicates the location of the decimal point in the u32CalorificValue field (below). The most significant 4 bits indicate the number of digits after the decimal point. The remaining bits are reserved
u32IssuerEventId is a unique identifier for the calorific value information - the higher the value, the more recently the information was issued
u32StartTime is the start-time of the calorific value. This is the time at which the conversion factor value is scheduled to become active
u32CalorificValue is used only for gas and indicates the quantity of energy in MJ that is generated per unit volume or unit mass of gas burned (see u8CalorificValueUnit). The position of the decimal point is indicated by u8CalorificValueTrailingDigit described above
