Expression High Event
Expression High triggers a procedure or calls a script when the value of the expression goes from LOW (zero) to HIGH (non-zero) while the screen is being displayed in CimView.
| Field | Description | ||||
|---|---|---|---|---|---|
| A | Expression | One or more Point IDs and mathematical operators that can be evaluated. | |||
| B | Action | Contains a drop-down list of existing procedures and scripts. Use either of the following. | |||
| Procedure | |||||
| Script | |||||
| C | Parameter | Can be used if the event invokes a script directly or through a procedure. The default code begins as follows. Sub OnExpressionHigh(exprValue As Variant) Where parameters are: | |||
| exprValue | |||||
| D | Debounce event | Check | |||
| Clear | |||||
|
Note: When debouncing is enabled, the event/action queue is always processed one action at a time; the current action must be completed before the next action can start.
This makes the queue's event/action sequencing predictable and avoids situations where many events could trigger actions and consume unacceptable levels of CPU and memory.
