(3) Point Logging mode: Set Mode=2, turn the instruction EN to ON before the recording starts. One log point would
be recorded for each triggering at external input point until it reaches the pre-defined point number, Cmplt flag
would set to High automatically. If you need to the recording to be continued after the Cmplt flag is set to High,
execute the instruction again.

Example:
Set Points = 2000, the trigger timing for external input point is set to rising-edge triggered.

(4) Fixed period + Trigger position Assign mode: Set Mode=3 and set parameters Points and PostTrg according
to your requirements. This mode is to trigger at the external input point and record the pre-defined number of
log points before and after the triggering occurs. When using EN to turn on this mode, AS02ADH-A would start
waiting for signals to be triggered at external input. And the sampling would start right after, until it reaches the
pre-defined point number, and then Cmplt flag would set to High automatically. The value in CurNo is 0 before
triggered, and after triggered, the modules start to send the before-triggered data log to the PLC CPU . Therefore
the value of CurNo would catch up to the number of accumulated log points.
