Inputs

Name	Type	Description
pInputBuffer_UL1 .. UL3	POINTER TO INT	Pointer to an array of voltage values. These can be added individually or as an oversampling array.
pInputBuffer_IL1 .. IL3	POINTER TO INT	Pointer to an array of current values. These can be added individually or as an oversampling array.
nInputBufferSize	UDINT	Indicates the size of a single input buffer in bytes.
pOutputBuffer_UL1 .. UL3	POINTER_TO_LREAL	Pointer to an array in which the scaled voltage values are to be stored.
pOutputBuffer_IL1 .. IL3	POINTER_TO_LREAL	Pointer to an array in which the scaled current values are to be stored.
nOutputBufferSize	UDINT	Indicates the size of a single output buffer in bytes.
bEL3783_HcRangeActive	BOOL	Autorange mode is active at the terminal.
aEL3783_HcRange	ARRAY [0..3] OF USINT	The current measuring range information for the EL3783.

Return value
