2 Running.
3
In the tripped trigger state. The condition has
become true, and the post samples are being taken.
4
In the forced trigger state. The trigger condition
was forced to be true so that the post samples
could be taken.
Trend Sample Size is always 500.
Post Samples specifies the number of samples that are taken once the
trigger condition has been tripped or is forced. One sample is used
for the instance when the trigger becomes true.
Operator data specifies how to compare the two data values for the
trigger condition.
Sample Time Rate specifies the rate of sampling data value. An
entry of 1 specifies 2 milliseconds.
Mode specifies whether a continuous trend or a one–shot trend is
performed.
If Comparison A Value is non-zero, the value specifies a constant
value to use as Operand X. You need to specify the Comparison A
Value in internal drive units. If Comparison A Value is zero,
Operand X is specified by Comparison A Link.
