Switching Sheet Step States

Switching sheet steps go through stages or states, just like switching sheets. Step states are described below:

Note: The status of steps that are executed in Study mode is prefixed with a two-character text string. (The default prefix is "ST," but this is configurable during system implementation.) Thus, a step that was completed in real-time mode would display the status "Completed," while a step completed in Study mode would display "ST Completed."

• No state - No action is associated with the step.

• Instructed - The step was instructed.

• Uninstructed - The instructed step was uninstructed.

• Completed - The step was successfully completed.

• Partially Completed - This state applies only to parent aggregate steps and indicates that some but not all child steps were completed.

• Previously Completed - This state occurs when a step is completed, but the asset was already in the desired state.

• SCADA Pending - This state applies only to actions that the system identifies as SCADA actions (that is, actions on telemetry-controlled assets). It indicates that a SCADA action was instructed.

Note: If the system detects that the asset was operated as instructed, the step state is then changed from SCADA Pending to Completed. If an error or timeout occurs, the step remains in SCADA Pending state.

• Deleted - The step was deleted from the sheet.

• Aborted - The step was marked as aborted by the user. (A step transitions to this state when the user selects the Abort option on the Steps toolbar.)

• Failed - The step was marked as failed by the user. (A step transitions to this state when the user selects the Fail option on the Steps toolbar.)Optimization

Note that a terminal action (Complete, Delete, Abort or Fail) must have been taken for each of the switching steps before a sheet can be completed.
