StageExceededBehavior

Basis to determine when the stage duration is exceeded.

Options:

• Snapshot - When the cycle manager enters the stage, it takes a snapshot of the value of the DurationExpression and uses this value to determine whether the stage has exceeded its duration.

• Dynamic - When this option is selected, the cycle manager dynamically responds to changes in the expected duration. If there is a change to the expected duration while the stage is active, this affects the IsStageExceeded and IsActiveStageExceeded results.

Snapshot, Dynamic

TransitionMode

Specifies whether the stage transition to the next stage is based on the results of an expression or a manual operation.

If manual, then define the ManualEnabledExpression property.

Manual, Expression

DetectStageOverrun

Specifies whether to detect when the stage has overrun its expected duration.

If you select True, specify the DurationExpression.

True, False

DurationExpression

Expression that determines when the expected duration for the stage is exceeded in number of seconds.

This property appears only when the value of DetectStageOverrun is set to True. If a stage is active for longer than its expected duration, AVEVA™ Production Management raises a Stage exceeded event.

For example: A constant value like 120 or an expression such as Project.ScadaConnector.AcidCycleDuration.Samples[time].
