Name |
Type |
Description |
|---|---|---|
|
pInputBuffer_U |
POINTER TO INT |
Pointer to an array of voltage values. These can be added individually or as an oversampling array. |
|
pInputBuffer_I |
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_U |
POINTER_TO_LREAL |
Pointer to an array in which the scaled voltage values are to be stored. |
|
pOutputBuffer_I |
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. |
|
bUse_5A_Range |
BOOL |
If the value is TRUE, the 5 A measuring range of the EL3783 is used. If it is FALSE, the 1 A measurement range is used. |
