Detailed Description

Function Documentation

naibrd_VR_GetMeasurement()

NAIBRDFUNC nai_status_t NAIAPI naibrd_VR_GetMeasurement	(	int32_t	cardIndex,
		int32_t	module,
		int32_t	channel,
		nai_vr_measured_value_type_t	measValueType,
		float64_t *	p_outMeasurement )

Retrieves a measurement from the specified VR channel, based on the measured value type specified. NOTE: For FPGA Revision 2.2 and greater, the maximum input is 100V. For FPGA Revisions less than 2.2, the maximum input is 65V.

Parameters

cardIndex	: (Input) Logical Card Index assigned to connection with the NAI_BOARD (0 - NAI_MAX_CARDS-1).
module	: (Input) Module Number of the module to access (1 - [max modules for board]).
channel	: (Input) Channel Number of the channel to access (1 - [max channels for module]).
measValueType	: (Input) Measured value type: refer to nai_vr_measured_value_type_t definition.
p_outMeasurement	: (Output) Measured value read from module.

Returns

• NAI_SUCCESS
• NAI_ERROR_INVALID_CARD when invalid card parameter is specified.
• NAI_ERROR_INVALID_MODULE when invalid module parameter is specified.
• NAI_ERROR_INVALID_CHANNEL when invalid channel parameter is specified.
• NAI_ERROR_INVALID_VALUE when invalid measValueType parameter is specified.
• NAI_ERROR_NOT_SUPPORTED when function is not supported.
