Select Trans_High Accum in the Calculation Type field on the Virtual tab.
A TransHigh Accum point accumulates the number of times the Expression value transitions from a zero to a nonzero value. While the CIMPLICITY project is running, the Trans_High Accum point remembers its latest state, even if the points it depends on become unavailable.
Determining a transition takes into consideration the calculation type of the expression and the point type of the TransHigh Accum point.
Important: Transition points are not supported in redundancy.
Example
If the TransHigh Accum point type is DINT and the Expression uses floating point arithmetic, the result of the calculation is rounded to the nearest integer. For example, a value of 0.1 is considered to be zero, and a value of 0.6 is considered to be nonzero.
If the TransHigh Accum point type is FLOAT and the Expression uses floating point arithmetic, then a transition from 0 to 0.1 is considered to be a transition from a zero to a nonzero value.

Expression 
Enter an expression in the Expression field on the Virtual tab of the Point Properties dialog box.
Enter an expression that calculates the value of the TransHigh Accum point.
The expression will be monitored for transitions.
The expression may contain:
One or more Point IDs as well as
Constant values, operations, and functions.
Buttons to help with the equation are as follows.

Opens the Expression Editor. 

Displays a Popup menu to: 



Open: The Select a Point browser. The Point Properties dialog box for a selected point. A New Point dialog box. The Expression Editor. Display an extended menu with the associated operations. 
Reset point 
Based on whether there is an entry in the Reset Point field, at runtime the TransHigh Accum point is reset as follows:

Note: Buttons to the right of the Reset Point and Trigger Point fields help with configuration.

Opens the Select a Point browser to select an available point. 

Displays a Popup menu to: 



Open: A New Point dialog box. The Point Properties dialog box for a selected point. The Select a Point browser. Select a recently selected point. 
Trigger point 
When the value of the TransHigh Accum point updates depends on whether or not you defined the trigger point as follows:
Trigger point 
The Value of the Min Capture Point is 
Defined 
Trigger point is updated. 
Not defined 
Source point in the Expression field is updated. 
Buttons to help with the trigger point have the same functionality as the buttons to the right of the Reset Point field.
