A
[Function]
The reception status of the database for the database operation from the NC is stored here.
[Operation]
bit0: "1" is set while accepting database operations for the machining result table.
bit1: "1" is set while accepting database operations for the alarm history table.
bit2: "1" is set while accepting database operations for the arbitrary information accumulation table.
"0" is set when the database operation is completed.
