ST_OCPP1_SampledValue

From the point of view of the OCPP specification, a Meter Value is a Sampled Value with a timestamp. In this PLC library, the timestamp is also managed in the Sampled Value in order to have one structure level less.

Parameter

Name	Type	Optional	Description
fValue	LREAL	No	Sampled Value as a decimal number ("Raw"). "SignedData" is not supported.
nTimestamp	ULINT	Yes	Timestamp of the Sampled Value.
eContext	E_OCPP1_ReadingContext	Yes	Context in which the Sampled Value was recorded (start, end or sample).
eFormat	E_OCPP1_ValueFormat	Yes	In this implementation, it is always the "Raw" format.
eMeasurand	E_OCPP1_Measurand	Yes	Type of the Sampled Value.
ePhase	E_OCPP1_Phase	Yes	Information on the interpretation of the Sampled Value.
eLocation	E_OCPP1_Location	Yes	Location of the Sampled Value.
eUnit	E_OCPP1_Unit	Yes	Unit of the Sampled Value.
