AO_SetSafeValues
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 |
Fail |
Refer to Return Codes. |
