TC_Reads

 

This function code is used to read the temperature value of contiguous channels.

 

C/C++

int TC_Reads( int hConnection,

BYTE bytSlot

BYTE bytStartChannel,

BYTE bytCount,

double dValue[ ]);

 

Visual Basic

Declare Function 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 32. 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 0x7fffffff, 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
