Transition high accumulator points accumulate the number of times the value of the expression in the point_expression field transitions from a zero to a non-zero value. During the execution of a CIMPLICITY project, a Transition High Accumulator point remains in its latest state even if the points it depends on become unavailable.
A Reset condition occurs when the reset point is updated, causing the transition high accumulator point to reset. The reset point can be activated by an operator or automatically by the system.
Determining a transition takes into consideration the calculation type of the equation and the point type of the transition high accumulator point. For example:
If the transition high accumulator
point is DINT, and the equation uses floating point arithmetic, the
result of the calculation is rounded to the nearest integer. Thus,
a value of 0.1 is considered to be zero, and a value of 0.6 is
considered to be non-zero.
If the transition high accumulator
point is FLOAT, and the equation uses floating-point arithmetic,
then a transition from 0 to 0.1 is counted as a transition from a
zero to a non-zero value.
Specifications
The transition high accumulator point is a derived point with the calculation_type set to 7.
