Functional Analysis Mode

At a Glance

The functional analysis mode provides a detailed list of the developments of the process.

The Data Table

Each development is listed in a table in chronological order. Only the variables included in the selected module are listed. The scroll bar, on the right-hand side of the window, enables you to scroll through the table rapidly. The size of the scroll bar depends on the relative size of the data zone displayed in the window in comparison with the size of the whole recording.

For each development, the user can obtain the following information:

Comment	Comment on the variable that has changed status.
Start date	The date (day/month/year) on which the status change occurred.
End date	The date (day/month/year) on which the new status disappeared.
Duration	The duration of the development.
Start time	The time (hour:minutes:seconds,milliseconds) at which the new status appeared.
End time	The time (hour:minutes:seconds,milliseconds) at which the new status disappeared.
Mnemonic	The mnemonic of the variable that has changed status.
Value	The new value of the variable that has changed status.
Variable	The name of the variable that has changed status.

It may be difficult to calculate values based on two successive developments of the variable, simply because the next development has not occurred yet. In such a case, the value indicated by Trending Tool is replaced by a single hyphen. There are different ways to configure the data table. As specified in this section, you can add, change or delete columns in order to modify the Trending Tool default display. The table can be copied to other office IT applications. You can also change the display of the data lines.

Adding a Column to a Table

In the FA Diagram mode, proceed as follows to add a column to the data table:

Step	Action
1	Move the mouse pointer onto the column header banner where you want to insert a column and right-click.
2	Use the Insert column command from the context-sensitive menu. This command opens a new column dialog box.
3	Complete the dialog box with the information you wish to obtain and click on OK.

Viewing FA Display Options

This dialog box enables you to manage the display of the FA diagram columns or statistical data table in trend diagram mode.

Dialog box options	Description
Item	Select the type of information you need in the drop-down list.
Title	Type the title of the column in this editor. If the field is left blank, Trending Tool will choose a default title depending on the item you selected.
Alignment	Select the alignment mode for the data in the column from the three options in the drop-down list. The data can be left or right aligned or centered in the column.
Width	Set the column's width in this field, either by directly typing a number in the editor or by changing the displayed width using the arrows to the right of the editor.
OK	Close the dialog box and apply the changes made.
Cancel	Close the dialog box without applying any changes.
Apply	Apply the changes made without closing the dialog box.
Help	Open a window featuring an online help related to the dialog box properties.

Changing Information in a Column

In the FA Diagram mode, proceed as follows to change the data contained in a table column:

Step	Action
1	Move the mouse pointer onto the column header banner where you want to change a column and right-click.
2	Use the Properties... command from the context-sensitive menu. This command opens a column properties dialog box.
3	Change the dialog box according to the information you wish to obtain and click OK.

Moving a Column

Proceed with the following steps, using the Drag & Drop method, to reorganize columns in a table:

Step	Action
1	Move the mouse pointer onto the column header banner where you want to move a column and left-click.
2	Hold your finger down while moving the mouse. The column is gray toned and superimposed over the banner.
3	Once the column has been moved to the required place, release the mouse button.

Deleting a Column

In the FA Diagram mode, proceed as follows to delete a column from the data table:

Step	Action
1	Move the mouse pointer onto the column header banner where you want to delete a column and right-click.
2	Use the Delete column command from the context-sensitive menu.

Changing the Display

There are three different types of Trending Tool variable: inputs, outputs and variables internal to the control system. To easily analyze the operation of an automated system, you may control the action and reaction sequences. With Trending Tool, you can allocate a color to each type of variable and therefore view the action sequences easily.

Proceed with the following steps to differentiate the lines in the data table:

Step	Action
1	Move the mouse pointer onto the table and right-click.
2	Select the Display... command from the context-sensitive menu. This command opens a dialog box defining the FA Diagram display parameters.
3	Set up the display parameters in the dialog box and click on OK.

Viewing FA Display Mode

This dialog box enables you to configure the display of the FA diagram mode. The display depends on the types of variable configured in Trending Tool. By default, all the variables are considered as internal variables in Trending Tool.
