Output Bit
Each point of digital output is called an output bit.
If a device with 4 output points, the bits are defined as bit 0 to bit
3.
Output in Bit Unit
Specify a output bit and specify the output data is 1 or 0, the state of that bit is changed to ON or OFF.
Use function AioOutputDoBit to digital output in bit unit.
Ret = AioOutputDoBit ( Id , DoBit , DoData )
In DoBit, specify the bit number for digital output.
If a device with 4 input points, the bit number that can be specified is
0, 1, 2, 3.
In DoData, specify the data for digital output.
Set 1 to turn ON the specified bit. Set 0 to turn OFF the specified bit.
Input in Byte Unit
Each output bit can be collectively output in byte unit.
If a device with 4 input points, each output bit is arranged as follows,
and the byte data that can be output is a value from 0 to 15.
Example) If output Bit0 : ON, Bit1 : OFF, Bit2 : ON, Bit 3 : OFF
Byte
data = 5 (5H)
Use function AioOutputDoByte to digital output in byte unit.
Ret = AioOutputDoByte ( Id , DoPort , DoData )
In DoPort, specify the port number for digital output.
If a device with 4 output points, the port number that can be specified
is 0 only.
In DoData, specify the data to digital output.
The output data for each bit is specified as a byte data.
