Flow of data processing
(1) When reading or writing data
1.
The host sends a request message (the read/write
command) to the GOT.
2.
The GOT performs a read/write processing to its
virtual devices according to the request from the host.
3.
Upon completion of the processing, the GOT sends a
response message (processing result) to the host.
4.
Creating the following objects on the screen allows
you to use the data read/written to the virtual devices:
• Numerical Display that displays data written by the
write command
• Numerical Input that is used to input data to be
upload to the host
