RTD_ReadRaws
This function code is used to read the temperature raw data for contiguous channels.
C/C++
int RTD_ReadRaws( int hConnection,
BYTE bytSlot,
BYTE bytStartChannel,
BYTE bytCount,
WORD wValue[ ]);
Visual Basic
Declare Function RTD_ReadRaws Lib "MXIO.dll" (ByVal hConnection As Long, ByVal bytSlot As Byte, ByVal bytStartChannel As Byte, ByVal bytCount As Byte, iValue As Integer) As Long
Arguments:
hConnection |
The handle for an I/O device connection. |
bytSlot |
Slot number of the I/O module. The Slot number ranges from 1 to 32. But this parameter is inactive in ioLogik 2000. |
bytStartChannel |
Specifies the starting channel. |
bytCount |
The number of channels to be read. |
wValue |
An array that stores the temperature value to be read. The wValue[0] represents the start channel. When the wValue 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 1~2000Ω, 100mΩ/1count. When using the RTD module for Resistance Input 1~327Ω, 10mΩ/1count. When using the RTD module for Resistance Input 1~620Ω, 20mΩ/1count. When the operating mode is temperature sensor, 0.1C(F)/1count, depending on the setting. Check the ioAdmin utility for current settings. |
Return Value:
Succeed |
MXIO_OK |
Fail |
