BYTE bytSlot,
BYTE bytStartChannel,
BYTE bytCount,
double dValue[ ]);
Visual Basic
Declare Function E42_AI_Reads 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 16. But this parameter is inactive in ioLogik 2000. |
bytStartChannel |
Specifies the starting channel. |
bytCount |
The number of channels to be read. |
dValue |
An array that stores the contiguous A/I channel's value, dValue[0] represents the value of the starting channel. The unit is Vdc for the voltage module, and mA for the current module. |
