Tag Browser Window

The "Tag Browser" window can be opened with the "..." button in all  object or resource properties where variables or dynamic links can be entered. This window displays a list of all the project's variables and dynamic links (OPC, Networking and Communication Drivers and Data Base fields) which can be selected and then inserted in the object and resource properties.

The "Tag Explorer" window can also be opened with the F8 key when using the following windows to edit script codes or IL logic:

• Script Explorer Window

• Logic Explorer Window

• Dynamic Property Inspector Window

The "Tag Explorer" window opens when pressing the F8 key and after having selected the variable, the focus will return to the point in which the variable was inserted in the code. This will reduce the number of clicks/operations which are usually needed to add variables to code.

The types of selections available when using Tag Browser's Tabs are:

Variables

This window shows the list of the variables available in the Real Time DB for the project currently opened. The command buttons presented are:

Refresh: refreshes the list taking into account any filter conditions inserted in the "Filter" field

New...: inserts a new variable in the Real Time DB by opening a window where you can also edit the new variable's properties

Expression...: opens a VBA Expression editor to allow you to insert a "Basic Script Expressions " (this will replace the individual variable)

Variable properties can be edited by using a window which opens by right-clicking on the variable you wish to edit.

Child Project Variables

This window shows the list of variables available in the Real Time DB of eventual child projects. The 'Refresh' and 'New' command buttons are provided with the same buttons provided in the "Variables" group but they refer to the child project's Real Time DB.

Network

This window allows you to select a local project or one from a PC on the network and displays a list of the variables which the project has been provided with for networking.

OPC

This window is used to select a local or remote  OPC DA Server in a networked PC and it displays the list of OPC DA Items that the Server has available for all OPC DA Clients.

Comm. I/O Drivers

This window consents you to add dynamic links to the Communication Driver. The Drivers inserted in the project will be displayed on the list and Tasks can be entered by double-clicking on the driver of interest.

DB Fields

This window shows the list of fields which can be associated to the Movicon "Embedded Report" objects.  These fields are in fact table columns resulted from the query associated to the Report.  For example, if the Report has not been associated with any custom query, all the columns in the table will be listed because the default query of the Report requires the extraction of all the data in the table.  However, if a custom query has been specified in the report's "Query Report" property, the list of fields will only show those columns of the resulting recordset.  In addition, it is also possible to enter the name of the recordset field in the query, for example, by applying a query with aliases as the column names.  For example, if you execute the following query:

SELECT UniID, EvDescCol, Count(UniID) AS Frequency FROM Alarms WHERE EventCol = 'ALARM OFF' GROUP BY UniID, evDescCol ORDER BY 3 DESC

It will be possible to select the "Frequency" field from the list of fields even though it is infact not a column from the "Alarms" table.

When enabling the  "Alarm Statistic" option afterwards, additional fields will be made available on the list of which you can select for the Alarm statistics. These fields are:

_TotalNumOn_

_TotalNumAck_

_TotalNumReset_

_TotalTimeOn_

_ProgressiveId_

_DateTimeOn_

The values of these additional fields, which do not belong to any of the tables, will be taken from statistical data of each individual alarm.  These statistical data are the same data described in the "Alarm Statistic" and "Alarm Status File" paragraphs.

Movicon must be able to access the database in order to compile the list of fields which are available. If this is not possible due to various reasons, e.g. because there is no ODBC connection or it is incorrect, or because the data extraction query is incorrect, one of the following error messages will show:

• Error when connecting to the report datasource (see the Output window for more information)

• Error when executing the report query (see the Output window for more information)

A this point, you will be abe to obtain more information on the error type by opening the Movicon Output window and going to the "DBMS Log " tab.

Applying filters to variables

When the "Variables" and "Child Project Variables" tabs are selected in the Tag Browser, three input fields will be made available for applying filters to the variable lists to be displayed   These three fields are:

• Filter by Name: the text entered in this field is used to filter the table's "Name" column, therefore the name of the variable.

• Filter by Desc.: the text entered in this fileld will be used to filter the table's "Description" column, therefore any variable descriptions

• Filter by Dyn: the text inserted in this field will be used to filter the "Dynamic" column, therefore any variable dynamics.

All three entry fields support the use of the  "*" and "?" characters and they can be used simultaneously for applying more detailed filters. In this case, the three filter clauses are entered with "and" between each one.  Once the filter has been set, use the "Refresh" button to apply the filter, or use the "enter" button when the cursor is within one of the input fields.
