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
