RTD2K_SetMathPars

This function code is used to set contiguous RTD channel's math

parameter.

C/C++

Arguments

Return Value

int RTD2K_SetMathPars ( int hConnection,

BYTE bytStartChannel,

BYTE bytCount,

WORD wMathPar[ ]);

hConnection: The handle for an I/O device connection.

bytStartChannel: Specifies the starting channel.

bytCount: The number of channels to be sets.

wMathPart: An array that stores the contiguous RTD

channel's math parameter, wMathPar[0]

represents the value of the starting channel.

The values are :

For AVG,Bit 0 of high byte represents the

first channel and Bit 1 of high byte

represents the second channel.

For DEV,High-Byte as subtrahend and

Low-Byte as minuend.

Exp : AVG( b’0000-0000 b’0010-0011) = ch5+ch1+ch0

Exp : DEV( b’0000-0100 b’0010-0000) = ch2-ch6

Succeed MXIO_OK.

TC_Reads

This function code is used to read the temperature values for

contiguous channels.

C/C++

Arguments

Return Value

int TC_Reads ( int hConnection,

BYTE bytSlot,

BYTE bytStartChannel,

BYTE bytCount,

double dValue[ ]);

hConnection: The handle for an I/O connection.

bytSlot: Slot number of the I/O module, from 1 to 32.

This parameter is inactive for the ioLogik

E2000 and R2000.

bytStartChannel: Specifies the starting channel.

bytCount: The number of channels to read.

dValue: An array that stores the temperature values of

the contiguous channels. dValue[0] represents

start channel 0. When 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 v. Use ioAdmin to check the

I/O module settings.

Succeed MXIO_OK.
