The trip function can be used by itself, included in If statements or
Case statements as the logical result of either passing or failing a
conditional test, or included in a sequence function step.
To insert a Trip function:
U Press the OTHER... soft key
U Press the TRIP dimension key
Continuous sampling using the trip function
Typical applications using the Trip function include the use of set and
trigger thresholds as discussed. However, some applications are
configured with the input channel devices in constant contact with the
surface(s) to be measured, and require continuous input sampling.
Continuous input sampling can be achieved by omitting the set and
trigger thresholds from the standard Trip function syntax.
Trip function syntax
A = trip(Value, set, trigger, delay)
Value can be a term or collection of terms.
Example:
A = trip(C1,0.1mm,0.5mm,1.0sec)
A = C1 will be stored in the database after the value of C1 has
passed through 0.1 mm, then 0.5 mm and then 1 second has
passed.
The examples shown for the Trip function used channel
functions. However, any term or collection of terms that
have numeric value could as easily have been used.
