8–5Using the Trend Features
Publication 1336 FORCE–5.18 ––March, 1999
You also need to specify the number of data samples to be taken
once a trigger condition occurs. You can specify that 0 to 499 post
samples be taken. One sample is reserved for the instance when the
trigger condition becomes true.
Note: “Pre–samples” are samples taken prior to the trigger
condition becoming true.
Important: Typically, when a trend buffer is set to trigger on a
fault, you would set the post sample quantity to a lower value, such
as 20. This allows you to evaluate the trended parameter’s data from
before the trigger.
When a trend buffer is set up as a level detector, the post sample
value is generally set to a higher value. This allows you to evaluate
what happened after the trigger occurred.
1. Determine the number of samples to be taken after the trigger
point becomes true.
2.
If you are programming
Trend:
Then enter the post trigger samples
in:
1 Parameter 459
2 Parameter 469
3 Parameter 479
4 Parameter 489
Important: If the trigger condition occurs before the pre–samples
can be taken, the pre–samples may be unreliable. The pre–samples
are valid only if the trigger does not occur before the pre–sample
time has elapsed. You can use the following equation to determine
pre–sample time:
T

= (500–S
