TC_Read

This function code is used to read the temperature value of a

specific channel.

C/C++

Arguments

Return Value

int TC_Read ( int hConnection,

BYTE bytSlot,

BYTE bytChannel,

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.

bytChannel: The desired channel.

dValue: Stores the temperature value of the desired

channel. When dValue is 0x8000, it means the

sensor is not wired correctly. 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.

Fail Refer to Return Codes.

TC_ReadRaws

This function code is used to read the temperature value of

contiguous channels in raw data format.

C/C++

Arguments

Return Value

int TC_ReadRaws ( int hConnection,

BYTE bytSlot,

BYTE bytStartChannel,

BYTE bytCount,

WORD wValue[ ]);

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.

wValue: An array that stores the temperature values of

the contiguous channels in raw data format.

wValue[0] represents start channel 0. When

wValue is 0x8000, it means the sensor is not

correctly wired. When the operating mode is

temperature sensor, 0.1°C (°F). When the

operating mode of the TC module is -78.0 ~

78.0 mV, 10 uV/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.

Succeed MXIO_OK.

Fail Refer to Return Codes.
