Flows with Change of In / Out of Service Between Cases

This analysis rule includes the flow elements that have changed service status from in-service (IS) to out-of-service (OS) or from OS to IS, or have remained OS between the current and the previous case. This change is significant and can indicate the following:

  • A change in operations, such as a lineup change
  • An error in service status

The following table lists a sample log output for this analysis.

Analysis Method​

  1. Collect a list of all flow elements of the Model for the current Case and from the previous case.
  2. For each flow, determine if there has been a change in in-service status by checking the service Attribute value for the strings "IS" and "OS" (Case insensitive) in the previous Case and the current case.
  3. Write to the log section of the case. Report the flow name, service status change and connection information.

Configuration Using the Wizard​

The configuration of the Flows with Change of Service is a selection of the General Gross Error Analysis Rule. You open the window for configuring the test (shown in the following figure) from the General Gross Error Analysis Rule Wizard.

  1. Open the Gross Error Configuration window as described in Configuring - General Gross Error Analysis Rule.

  2. On the Flows tab, select Flows with change of in/out service between cases.

    A Flows with change of in/out service between cases - Attributes window opens.Figure 403: Flows with change of in/out service between cases - Attributes window

  3. Select the Attribute for In-Service Status. The following table provides a description.
