Event Processing (When Using Direct Connection)
When the status of the NT20S changes during operation, the processing for writing the changed data to the relevant
area of the PC memory is executed.
This kind of processing is only executed when statuses change. When changes occur simultaneously, the proces-
sings are executed in accordance with the order of priority.
Data is only written to PC bits and numeral/character string memory tables for elements in screens currently being
displayed. If the contents of numeral/character string memory tables that are not being displayed change, the
changed data is not written to the PC.
