Analysis

1. Log in to the Plant Applications Universal Client.
2. Select .

   The Chart Configuration page appears.

3. In the Plant Model list, select a plant model associated with the process order.
4. In the Data type list, select Process Orders.
   Note: The Process Orders option appears only when the Plant Applications universal client is configured to use process orders instead of batches.
5. Search for the process order that you want to analyze, and then, in the Process Orders section, select Add Process Orders.
   Tip: You can add multiple process orders to compare their details.
6. Select Plot to access the CHART CONTROLS page, and then analyze the process order.
   Tip: Alternatively, you can select to access the CHART CONTROLS page.

   By default, the CHART CONTROLS page appears in Normal View and a Gantt chart appears for the selected process order.

   If you selected only one process order, the process order available in the five days before and after the selected process order also appears in the chart. You can hover over a process order to view its details. For more information about trend charts, refer to the Types of Trend Charts topic.

   In the CHART CONTROLS page, you can use the Toggle View option to toggle between the interval and duration modes.

   If you selected multiple process orders, then the Gantt chart appears in the duration mode only.

7. Analyze the selected process order with respect to variables in a Line chart by following these steps:
   1. Select to go back to the Chart Configuration page.
   2. In the Data type list, select Variables.
   3. Search for the variables you want to plot in the Line chart, then select Add Chart, and then select Plot to plot the selected variables for the selected process order in a single Line chart.
      Tip: Select Add Chart to add more charts and plot a single variable or a combination of variables in different charts.

   In the CHART CONTROLS page, the Line chart appears in the CHART 2 section after the Gantt chart as shown in the following image.

   

   You can set the time slider bar for the required time duration for the process order. When you update the time duration for the process order in the Gantt chart, the application updates the corresponding Line chart displaying the time series data. In addition, the application synchronizes the horizontal axis for the Gantt and Line charts.

You can use the Analysis application to analyze a batch, compare the batch with the other batches, navigate to previous and next batches, and compare how the variables associated with the batch produced trend over the batch duration. The ANSI/ISA???88.01???1995 documentation defines a batch as the material that is being produced or that has been produced by a single execution of a batch process or an entity that represents the production of a material at any point in the process. Batches are produced on a single equipment or a process cell. A golden batch is a batch that is identified to be used as a reference batch for a few specific KPIs such as the best yield, lowest waste, best quality, and higher productivity.

1. Log in to the Plant Applications Universal Client.
2. Select .

   The Chart Configuration page appears.

3. In the Plant Model list, select a plant model associated with the batch.

   Note: The Batches and Golden Batches options appear only when the Plant Applications universal client is configured to use batches instead of process orders.
5. Search for the batch that you want to analyze, and then, in the Batches section, select Add Batches.
   Tip: You can add multiple normal batches or golden batches to compare their details. For more information, refer to the Add Tags, Variables, KPIs, Process Orders, and Batches topic.
6. Select Plot to access the CHART CONTROLS page, and then analyze the batch.
   Tip: Alternatively, you can select to access the CHART CONTROLS page.

   By default, the CHART CONTROLS page appears in Normal View, displaying a Gantt chart for the selected batch. If you selected only one batch, the batches available within the five days before and after the selected batch also appears in the chart. You can hover over a batch to view its details. For more information about trend charts, refer to the Types of Trend Charts topic.

   In the CHART CONTROLS page, you can use the Toggle View option to toggle between the interval and duration modes.

7. Analyze the selected batch with respect to variables in a Line chart by following these steps:
   1. Select to return to the Chart Configuration page.
   2. In the Data type list, select Variables.
   3. Search for the variables you want to plot in the Line chart, then select Add Chart, and then select Plot to plot the selected variables for the selected batch in a single Line chart.
      Tip: Select Add Chart to add more charts and plot a single variable or a combination of variables in different charts.

   In the CHART CONTROLS page, the Line chart appears in the CHART 2 section after the Gantt chart as shown in the following image.

   

   You can set the time slider bar for the required time duration for the process order. When you update the time duration for the process order in the Gantt chart, the application updates the corresponding Line chart displaying the time series data. In addition, the application synchronizes the horizontal axis for the Gantt and Line charts.

You can add Historian tags, Plant Applications variables, KPIs, process orders, batches, and golden batches to the Analysis page to trend required charts and display tables for analyzing information.

1. Log in to the Plant Applications Universal Client.
2. Select .

   The Chart Configuration page appears. By default, the Tags option appears in the Data type list.

3. Select a context in the Plant Model list.
   Note: You must expand the plant name to navigate and select the required department, line, or unit of your plant. The selected department, line, or unit appears for the plant model in the Plant Model list.
4. Select the required Historian server in the Historians list.
   Note: The Historians list appears only when you select Tags in the Data type list. You can plot the Historian tags belonging to multiple Historian servers, limited to 10 servers only. The Historian server can be local or remote. A local Historian server is installed on the same node as the Process Analyzer. The remote Historian server is installed on a node different than that of the Process Analyzer. The minimum supported version is Historian 7.0 SP5 or later.
5. In the Data type list, select one of the following options:
   • Tags
   • Variables
   • KPI (available for lines and units only)
   • Process Orders (available only if the Plant Applications universal client is configured to use process orders)
   • Batches (available only if the Plant Applications universal client is configured to use batches)
   • Golden Batches (available only if the Plant Applications universal client is configured to use batches)

   Tip: To sort the search results, select a column name. To filter the data, select . For more information, refer to the topic Filter Tags, Variables, KPIs, Process Orders, and Batches.
6. Depending on the data type, select one of the following options as shown in the following table.

   Data Type	Option
   Variables	Add Chart
   KPIs	Add Chart
   Variables	Add Chart
   Batches	Add Batches
   Golden Batches	Add Batches
   Process Orders	Add Process Orders

   You can select multiple items.

   Note: To add multiple items to an existing chart, select Add Data for the chart. Alternatively, to add a new chart, drag the required items to the Add Chart button. GE recommends that you should restrict the total count of tags or variables for Live charts to five to optimize the trend chart output.
7. Select to select an interval from the available Presets or to select a custom time interval by selecting the required dates and time, and then select Apply.

   The default time duration selected is the current time minus one hour. If you select an interval from the calendar, the chart is enabled to be plotted as the Historical chart instead of the Live chart.

   
8. After you add the required items to the charts, select Plot.
   With larger data samples the loading time of the analysis session may increase.
   A live chart is plotted on the screen as Chart 1.

The Analysis page appears, displaying the required trend charts and information.

Tip: You can select to open the Chart Configuration page to search and add more tags, variables, KPIs, batches, or process orders for analysis. In the Chart Configuration page, you can select to open the Analysis page.
