Delta AS Series Programming Manual page 808

Example
Set Mode=3, Points = 2000, and PostTrg = 1500 so the position of point 501 (Points – PostTrg）would be the first record
after an external trigger signal is detected.

7. Period is set for the record period, which is detailed as follows:
Model Setting Range for Period
AS04AD-A
AS06XA-A
AS02ADH-A
8. Points is the number of total records which is only applicable for AS02ADH-A, and can set a maximum of 2000 records.
For other models, the setting value is fixed to 500.

9. PostTrg is the number of log points recorded after Trigger occurs which should be applied with Points, to record the
number of all records, including data before and after the triggering. PostTrg is only applicable for Fixed period +
Trigger position assign mode (Mode=3) and invalid for other modes. Please note that the value of PostTrg should not
be greater than the value in Points (the number of all records), or the value in PostTrg would be replaced with the
value in Points. For example, if Points＝100 and PostTrg＝200, the value in PostTrg would be seen as the value in
Points, which is 100, since the value in PostTrg is greater than the value in Points (the number of all records).
Therefore, only a number of 100 points would be recorded after the triggering occurs.

1~100 The unit is fixed to be 10ms, unchangeable.
The sampling period would need to be set in HWCONFIG with
1~32000 options of 20us, 40us, and 80us.
If set "Mode=2:Point Logging", the value of Period would be invalid.
The value is fixed to be 500, other setting value is invalid.
Configurable, the setting value ranges from1 to 2000.
