12-2 Setting Up Trending
Selecting the Parameter to Sample 1. Identify the number of the parameter that you want to sample.
2.
Setting the Trigger Condition The trigger condition defines the event that must be true before the
trend is triggered (activated). After the trend is activated and the
required number of post samples have been recorded, the last 500
samples for that trend are made accessible via the output parameter.
The following statement determines the trigger point:
[Variable X] [Operator] [Variable Y]
Variable X is compared to Variable Y. If the condition specified by
the Operator is true, then the trend is triggered. Typically, you link
one variable to a parameter and the other variable to either a
parameter or a constant value.
Important: You should make sure that you are comparing either both
signed parameters or both unsigned parameters. Trying to compare a
signed parameter to an unsigned parameter could cause unexpected
results.
If you are programming

Then enter the number of the parameter to be
sampled in:
1 P293
2 P305
3 P317
4 P329
