Unit configuration
n Digital output value (channel 0–3)
I
Buffer (unit memory)
Q Buffering at specified sampling cycle
W Pre-trigger buffering
E Post-trigger buffering
II Control and status flags
1 Buffer function control flag
2 Trigger flag
3 Pre-trigger number match flag
4 Buffering in progress flag
5 Buffering complete flag
6 Buffer reset flag
III Operation sequence
1 Pre-trigger buffering will start when the user program turns the buffer function
control flag to TRUE.
2 When the specified number of pre-trigger values is reached, the pre-trigger
number match flag turns to TRUE.
3 Buffering starts when the user program turns the trigger flag to TRUE. It continues until the specified number of buffered values is reached.
4 Buffering finishes when the specified number of buffered values has been captured.
5 The user program reads the buffered values and turns the buffer reset flag to
TRUE.
6 The unit restarts pre-trigger buffering and waits for the next trigger signal.
