E42_TC_Reads
This function code is used to read the temperature value of contiguous channels.
C/C++
int E42_TC_Reads( int hConnection,
BYTE bytSlot
BYTE bytStartChannel,
BYTE bytCount,
double dValue[ ]);
Visual Basic
Declare Function E42_TC_Reads Lib "MXIO.dll" (ByVal hConnection As Long, ByVal bytSlot As Byte, ByVal bytStartChannel As Byte, ByVal bytCount As Byte, dValue As Double) 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 16. But this parameter is inactive in ioLogik 2000. |
bytStartChannel |
Specifies the starting channel. |
bytCount |
The number of channels to be read. |
dValue |
An array that stores the temperature value to read. The dValue[0] represents start channel 0. When the dValue is 0x8000, it means the sensor is not correctly wired. When the operating mode of the TC module is voltage input, the unit is μv. Use ioAdmin to check the I/O module settings. |
Return Value:
Succeed |
MXIO_OK |
Fail |
