NOTE
1 The CNC side cannot write the next data before the
application side completes reading of the current data.
Keeping the CNC side waiting may reduce its
throughput. Once it has started the high-level process,
therefore, the application side should complete data
reading as quickly as possible by copying the data to
another area.
2 In the first high-level process performed after the power
is switched on, the application must ignore any high-level
data received from the CNC side.
(No data is set, because there is no "previous" high-level
process.)
