E1K_RTD_Reads
This function code is used to read the temperature value for contiguous channels.
C/C++
int E1K_RTD_Reads( int hConnection,
BYTE bytStartChannel,
BYTE bytCount,
double dValue[ ]);
Visual Basic
Declare Function E1K_RTD_Reads Lib "MXIO.dll" (ByVal hConnection As Long, ByVal bytStartChannel As Byte, ByVal bytCount As Byte, dValue As Double) As Long
Arguments:
hConnection |
The handle for an I/O device connection. |
bytStartChannel |
Specifies the starting channel. |
bytCount |
The number of channels to be read. |
dValue |
An array that stores the temperature value to be read. The dValue[0] represents the start channel. When the dValue is 0x7FFF, it means the sensor is not wired correctly, or the measured value is out of range. When using the RTD module for Resistance Input, the unit is Ohm. When the operating mode is temperature sensor, the unit is C or F, depending on the setting. Check the ioAdmin utility for current settings. |
Return Value:
Succeed |
MXIO_OK |
Fail |
