Arguments

Return Value

int TC_ReadRaw ( int hConnection,

BYTE bytSlot,

BYTE bytChannel,

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

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, 10uV/count. When the operating

mode of the TC module is -32.7 ~ 32.7 mV,

1uV/count. When the operating mode of the TC
