EX1629 Command Set 197
vtex1629_identify_sensor
FUNCTION PROTOTYPE
ViStatus _VI_FUNC vtex1629_identify_sensor (ViSession vi, ViInt32 channel, ViBoolean LEDOn);
FUNCTION PARAMETERS
vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
channel = an integer input value that specifies the channel for which the unstrained voltage will be returned. Valid
input values: 0 to 47.
LEDOn = a real return value that indicates the currently configured unstrained voltage for the given channel. Valid
input values: VI_TRUE = LED is on, VI_FALSE = LED is off.
DATA ITEM RESET VALUE
Not applicable to this function.
DESCRIPTION
The function provides the user the ability to control and LED co-located to a sensor to ease the sensor identification
process. Two LEDs cannot be illuminated on the same analog board (i.e. channels 0 through 15 are on one analog
board, channels 16 through 31 are on another, and channels 32 through 47 are on another board) if front panel shunt,
TEDS remote shunt, or internal shunt (remove) are active. If these conditions occur, an error will be generated.
EXAMPLE
ViSession instrumentHandle;
ViInt32 channel = 10;
ViBoolean LED = VI_TRUE;
status = vtex1629_identify_sensor(instrumentHandle, channel, LED);
