This function code is used to read the temperature raw data for a specific channel.
C/C++
int TC_ReadRaw( int hConnection,
BYTE bytSlot,
BYTE bytChannel,
DWORD * wValue);
Visual Basic
Declare Function TC_ReadRaw Lib "MXIO.dll" (ByVal hConnection As Long, ByVal bytSlot As Byte, ByVal bytChannel 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. |
bytChannel |
The specific channel to be read. |
wValue |
An pointer that stores the temperature value to read. When the wValue is 0x7fffffff, it means the sensor is not correctly wired. When the operating mode is temperature sensor, 0.1℃(℉). When the operating mode of the TC module is -78.0 ~ 78.0 mV, 10uV/count. When the operating mode of the TC module is -32.7 ~ 32.7 mV, 1uV/count. When the operating mode of the TC module is -65.5 ~ 65.5 mV, 2uV/count. Use ioAdmin to check the I/O module settings. |
