GX1632e

GxAoDioSetDirection (nHandle, nDioGroup, dwDirection, pnStatus)

Name	Type	Description
nHandle	SHORT	Handle to a GX1632e board.
nDioGroup	SHORT	Specifies the DIO group. Model dependent. GX1632e: 0. GXAO_1632_DIO_CH0_3 1. GXAO_1632_DIO_CH4_7
dwDirection	DWORD	The specified group’s direction. Model dependent. GX1632e: 0. GXAO_1632_DIO_DIRECTION_OUTPUT 1. GXAO_1632_DIO_DIRECTION_INPUT
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

On the GX1632e, changing direction from output to input does not change the data level on an undetermined channel.

The following example sets the direction of the low channels to input and the high channels to output:

SHORT nStatus;

GxAoDioSetDirection (nHandle, GXAO_1632_DIO_CH0_3, GXAO_1632_DIO_DIRECTION_INPUT, &nStatus);

GxAoDioSetDirection (nHandle, GXAO_1632_DIO_CH4_7, GXAO_1632_DIO_DIRECTION_OUTPUT, &nStatus);
