Remote I/O Communications Performance Section C-1
C-1 Remote I/O Communications Performance
This section explains the remote I/O communications performance of the
CompoNet Master Board.
C-1-1 Input time (Slave Unit
→
Master Board)
This is the input time for the CompoNet network. The input time refers to the
time until the input signal of an IN Slave Unit is captured by the Master Board
application.
The calculation formula for input time differs according to the type of Slave
Unit and the access method.
C-1-2 Output time (Master Board
→
Slave Unit)
This is the output time for the CompoNet network. The output time refers to
the time until the output signal from the Master Board application is outputted
to an OUT Slave Unit.
The calculation formula for input time differs according to the type of Slave
Unit and the access method.
