This function code is used to set the safe value for contiguous A/O channels.

 

C/C++

int AO_SetSafeValues( int hConnection,

BYTE bytSlot,

BYTE bytStartChannel,

BYTE bytCount,

double dValue[ ]);

 

Visual Basic

Declare Function AO_SetSafeValues Lib "MXIO.dll" (ByVal hConnection As Long, ByVal bytSlot As Byte, ByVal bytStartChannel As Byte, ByVal bytCount As Byte, dValue As Double) As Long

 

Arguments:

hConnection

The handle for an I/O device connection.

bytSlot

Slot number of the I/O module. The Slot number ranges from 1 to 32. But this parameter is inactive in ioLogik 2000.

bytStartChannel

Specifies the starting channel.

M-4402/M-4410 All Channels use the same safe vaule. Just only support bytStartChannel=0 && bytCount=1

bytCount

The number of channels to set.

dValue

An array that stores the contiguous A/O channel's safe value to set. The dValue[0] represents the value of the starting Analog output channel. The unit is Vdc for the voltage channel and mA for the current channel.

 

Return Value:

Succeed

MXIO_OK
