Event table

The event table element can be used to display TcEventLogger messages in the form of a table on a visualization page. The messages are read via the function block "FB_AdsReadEvents" and forwarded to the visualization element via an array. An example of the configuration of the element can be found in the section "Configuration of the event table". This element is available from build 4020.0.

Properties editor

The properties of a visualization element - except alignment and order - can all be configured in the properties editor. By default, this editor opens next to the visualization editor, or it can be opened explicitly via the "Properties" command (which can be found in the View menu as standard).

A property can be modified by editing the field "Value". To this end, an input field, a selection list, a dialog or checkbox that can be activated is provided in this field, depending on the element type. The value field opens

after a double-click,
after a single click in a selected field,
via the space bar, if the field was already selected.

If a variable is assigned,

simply enter its name.
Use the button to open the input assistant for selecting a variable. The Variables category lists all variables that have already been defined in the project.

Working in the list of properties can be made easier with the aid of default, sorting and filter functions.

Element properties

All element properties and their descriptions are listed below.

Element name

The element name can be changed. Standard name is "GenElemInst_x". "x" stands for a sequential number.

Element type

The element type is entered here. For three element groups it is possible to switch between the corresponding elements by changing the element type:

Position

Here you can define the position (X/Y coordinates) and size (width and height) of the element in pixels. The origin is in the top left corner of the window. The positive x-axis is on the right, the positive y-axis runs downwards. If the values edited, the displayed element is simultaneously modified in the visualization editor.

X	Horizontal position in pixels – X=0 is the left edge of the window.
Y	Vertical position in pixels – Y=0 is the upper edge of the window.
Width	Width of the element in pixels
Height	Height of the element in pixels

Columns

The element TcEventTable contains a table with the following seven columns:

Index: The index indicates the message numbers in the order in which they occurred.
Class: The class describes the message type. It is defined when a message is created.
Acknowledgment state: A message can be created with obligatory acknowledgment. The acknowledgment can take place in the program code or in the element. The state indicating whether the element is (still) to be acknowledged is displayed in this column.
Reset state: Once a message has been enabled, it can be reset in the program code. This row indicates whether the message was already reset.
Date, Time: The two columns ‘Date’ and ‘Time’ show the date and time at which the message has occurred.
Message: The actual message text is displayed in the last column.
