DO2K_GetPowerOnValues

This function code is used to get the power on values of

contiguous D/O channels.

C/C++

Arguments

Return Value

int DO2K_GetPowerOnValues ( int hConnection,

BYTE bytStartChannel,

BYTE bytCount,

DWORD * dwValue);

hConnection: The handle for an I/O connection.

bytStartChannel: Specifies the starting channel.

bytCount: The number of channels to read.

dwValue: A pointer to the power on values of the

contiguous D/O channels; each bit holds the

value of one channel. A bit value of 0

represents the power on status of the start

channel. A bit value of 1 represents the status

of the second digital output channel. The values

of the unused bits are random.

Succeed MXIO_OK.
