Advantages of an integrated visualization
For visualizing, that means watching and operating the data of a controller which has is programmed
with CoDeSys, no additional tool is required. The programming system contains an integrated
visualization editor (see CoDeSys User Manual), allowing the user to create visualization objects to
the parallel to the development of the application in the same user interface.
The integration offers a lot of benefits:
The visualization integrated in CoDeSys does not need a tag list and it can directly access the
variables in the controller. Any OPC- or DDE-layer, which often is difficult to configure, is also not
necessary, because the communication is done by the same mechanism which is used for the
programming system. Thus the engineering effort for the realization of visualizations will be clearly
reduced. Besides that the connection of controller and visualization allows running modes (see
below), in which the conventional display on a PC with a monitor is not needed any longer.
One of the main advantages of the concept: The visualization masks which are created in the
programming system can run in four different modes without requiring any modifications, if desired
even parallel:
1. Directly in the programming system
For testing the created visualization masks, but also for service or diagnosis purposes in direct
connection with the controller you do not need a further tool: In online mode you immediately get a
display of the visualizations within the programming system.

2. CoDeSys HMI
The program CoDeSys HMI, which displays visualizations on a PC without the complete development
user interface, also communicates via the programming interface. The configuration of OPC (OPC OLE for Process Control) – resp. DDE (DDE – Dynamic Data Excange) inteface is not necessary. See
chapter 3.
3. Web-Visualization
Optionally CoDeSys generates a description in XML format from the visualization data, which is
loaded to the controller together with a Java-Applet (Applet – a program developped in the
programming language JAVA, which can be processed by browsers) and which can be displayed via
TCP/IP on a browser. Thus the visuaization data are available online on various platforms. See
chapter 4.

1 - Advantages of an integrated visualization
4. Target-Visualization
For controllers with integrated display the visualization data can be loaded from the programming
system together with the application to the target system. There they get displayed automatically. This
solution can be portated with low effort to any devices which are programmable with CoDeSys. See
chapter 5.

The Visualization Editor in CoDeSys
Visualization - Overview
A visualization is a graphical representation of the project variables which allows inputs to the PLC
program in online mode via mouse and keypad. The CoDeSys visualization editor, which is part of
the programming system provides graphic elements which can be arranged as desired and can be
connected with project variables. Thereupon in online mode the look of the graphical elements will
change depending on the variables values.
Simple example: In order to represent a fill level, which is calculated by the PLC program, draw a bar
and connect it to the corresponding project variable, so that the length and color of the bar will show
the current fill level value. Add a text field which will display the current value in a text string and a
button for starting and stopping the program.
The properties of a single visualization element as well as of the whole visualization object will be
defined in appropriate configuration dialogs and in the object properties dialog. There it is possible
to set basic parameters by activating options as well as to define a dynamic parameterizing by
entering project variables.
Additional special possibilities for configuring are given by the programmability of element properties
via structure variables.
Using placeholders in the configuration dialogs may save a lot of effort in case you want to use the
same visualization object several times with different configurations.
The visualization which is created in the programming system will in many cases be used as the only
user interface available for controlling and watching the associated PLC program in online mode. For
this purpose it must be possible to give inputs to the program solely by activating visualization
elements. To reach this you can use special input possibilities during the configuration of the
visualization and you have the option to define special hotkeys for each particular visualization.
A visualization created in CoDeSys can later be used in different ways:
• It can be made available on CoDeSys HMI, a special runtime system for operating the
visualization in full screen mode on a PLC computer.
• It can be made available as a Web-Visualization, which allows to call and operate it via the
Internet (useful for remote maintenance purposes)
• It can be made available as a Target-Visualization, which can be started directly on the PLC.

2.1
Create a new Visualization
A visualization object is a CoDeSys object which is managed in the 'Visualization' register of the
Object Organizer. It contains an arrangement of visualization elements and can get certain object
properties. One or several visualization objects can be created in a CoDeSys project and might be
linked with each other.
In order to create a visualization object in the Object Organizer, you must select the register card for
Visualization in the Object Organizer.
Using the 'Project' 'Object Add' command, you can create a new visualization object. Open the 'New
visualization' dialog, in which you can enter the name of the new visualization. Once a valid entry is
made, that is not a name that is already in use and no special characters used, you can close the
dialog with OK. A window opens, in which you can edit the new visualization.
When the visualization object is marked in the Object Organizer, via command 'Project' 'Object'
'Properties' (see CoDeSys User Manual) the Properties dialog can be opened, where you can make
settings concerning the usage of the object in a Web- or Target-Visualization as well as concerning a
Master layout.
Please regard: If you want to use the implicit variable CurrentVisu (type STRING) for addressing the currently
opened visualization object, you throughout must use capital letters for the names of the visualization
objects (e.g. "PLC_VISU"). (For information on implicit variables see here)
2.2
Visualization Elements, Insert...
A visualization element is a graphical element, which is used to fill a visualization object. The available
elements are offered in the CoDeSys menu bar. Each element gets a separate configuration.
You can insert various geometric forms, as well as bitmaps, metafiles, buttons and existing
visualizations, into your visualization.
Geometric forms at your disposal include: rectangles, rounded rectangles, ellipses/circles, and
polygons.
Go to the 'Insert' menu item and select freely from the following commands:
'Rounded
Rectangle',
'Bitmap',
'Ellipse',
'Visualization',
'Polygon'‚
'Button',
Polyline',
'Table',
'Rectangle',
'Curve',
'ActiveX-Element',
'Pie',
'Meter',
'Bar Display',
'Histogram',
'Alarm table',
'Trend',
'WMF file'. A check appears
in front of the selected command. You can also use the tool bar. The selected element appears
pushed down(e.g.
).
If you now go to the editor window with the mouse, you will see that the mouse pointer is identified
with the corresponding symbol (e.g.
). Click on the desired starting point of your element and
move the pointer with pressed left mouse key until the element has the desired dimensions.
If you want to create a polygon or a line, first click with the mouse on the position of the first corner of
the polygon resp. on the starting point of the line, and then click on the further desired corner points.
By doubleclicking on the last corner point you will close the polygon and it will be completely drawn
respectively the line will be completed. If you want to create a curve (Bezier curves) determine the
initial and two other points with mouse clicks to define the circumscribing rectangle. An arc is drawn
after the third mouse click. You can then change the position of the end point of the arc by moving the
mouse and can then end the process with a double click or add another arc with additional mouse
clicks.
Furthermore pay attention, to the status bar and the change from select and insert modes.
Regard also the possibility of using placeholders and Master layouts.

value changes, a new entry will be made in the file, showing date/time and the new value.
The trend element is drawn transparently. So you can assign any desired background (bitmap, color).
2.3
Positioning of Visualization Elements...
Selecting Visualization Elements
The selection mode is activated by default. In order to select an element, click with the mouse on the
element. You can also select the first element of the elements list by pressing the <Tab> key and
jump to the next by each further keystroke. If you press the <Tab> key while pressing the <Shift> key,
you jump backwards in the order of the elements list.
In order to select elements, which are placed one upon the other, first select the top level element by
a mouse-click. Then do further mouse-clicks while the <Ctrl>+<Shift>-buttons are pressed, to reach
the elements in the underlying levels .
In order to mark multiple elements, press and hold the <Shift> key and click the corresponding
elements, one after another; or, while holding down the left mouse button, pull a window over the
elements to be selected.
In order to select all the elements, use the 'Extras' 'Select All' command.
In the element list (called by 'Extras' 'Element list') you can select an element in the visualization by
selecting the respective line.
Changing the Selection and Insert Mode
After the insertion of a visualization element, there is an automatic change back into the selection
mode. If you want to insert an additional element the same way, you can once again select the
corresponding command in the menu or the symbol
in the tool bar.
You can also quickly change between the selection mode and the insert mode by pressing the <Ctrl>key and the right mouse button simultaneously.
In the insert mode, the corresponding symbol will also appear at the mouse pointer, and the name will
also be indicated in black in the status bar.
'Extras' 'Select'
This command is used to switch the selection mode on or off. This can also be achieved using the
symbol
or by pressing the right mouse-key while holding down the key at the same time.
'Extras' 'Select All'
This command allows you to select all visualization elements within the current visualization object.
Copying Visual Elements
One or more selected elements can be inserted with the 'Edit' 'Copy' command, the <Ctrl>+<C> key
combination, or the corresponding copy symbol, and with 'Edit' 'Paste'.
The CoDeSys Visualization
2-7
2 - The Visualization Editor in CoDeSys
A further possibility is to select the elements and to again click in one of these elements with the
<Ctrl> key held down. If you now hold the left mouse button down, you can separate the elements
thus copied from the original.
Modifying Visualization Elements
You can select an element which has already been inserted by a mouse click on the element or by
pressing the <tab> key. A small black square will appear at each corner of each of the elements, (with
ellipses at the corners of the surrounding rectangle). Except in the case of polygons, lines or curves
further squares appear in the middle of the element edges between the corner points.
With a selected element, the turning point (balance point) is also displayed at the same time. You can
then rotate the element around this point with a set motion/angle. The turning point is displayed as a
small black circle with a white cross (
button.
). You can drag the turning point with a pressed left mouse
You can change the size of the element by clicking on one of the black squares and, while keeping
the left mouse button pressed, controlling the new outline.
With the selection of a polygon, you can drag each individual corner using the same technique. While
doing this, if you press the <Ctrl>-key then an additional corner point will be inserted at the corner
point, an additional corner point will be inserted, which can be dragged by moving the mouse. By
pressing the <Shift>+<Ctrl>-key, you can remove a corner point.
Dragging Visualization Elements
One or more selected elements can be dragged by pressing the left mouse button or the arrow key.
Grouping Elements
Elements can be grouped by selecting all desired elements and performing the command 'Extras'
'Group'. The group will behave like a single element:
• the grouped elements get a collective frame; when dragging the frame all elements will be
stretched or compressed; only the group can be moved to another position.
• the grouped elements get collective properties: inputs only can effect the group and not a single
element. Thus the elements also get one collective configuration dialog (category 'group'). The
property 'Change color' can not be configured for a group !
To redefine a single element of a group, the grouping must be redone by the command 'Extras'
'Ungroup'. The configuration of the group will be lost in this case.
Note: As soon as you save the project as CoDeSys Version 2.1 or lower, a group of visualization elements will be
resolved automatically; that means that the elements of the group will be shown as single elements in
the visualization.
'Extras' 'Send to Front'
Use this command to bring selected visualization elements to the front.
'Extras' 'Send to Back'
Use this command to send selected visualization elements to the back.
'Extras' 'Align'
Use this command to align selected visualization elements.
The following alignment options are available:
2-8
The CoDeSys Visualization
2 - The Visualization Editor in CoDeSys
• Left: the left edge of each of the elements will be aligned to the element that is furthest to the left
• the same is true for Right / Top / Bottom
• Horizontal Center: each of the elements will be aligned to the average horizontal center of all
elements
• Vertical Center: each of the elements will be aligned to the average vertical center of all elements
'Extras' 'Elementlist'
This command opens a dialog box containing a list of all visualization elements including their
number, type and position. The position is given according to the x and y position of the upper left
(x1, y1) and the lower right (x2, y2) corner of the element.
Element list dialog box
When one or more items have been selected, the corresponding elements in the visualization are
marked for visual control and if necessary the display will scroll to that section of the visualization that
contains the elements.
Use the To front button to bring selected visualization elements to the front. Use the To behind
button to move them to the back.
Below the elements list there you find – depending on which element is currently selected - one of the
following combinations of edit fields where you can modify size and position of the element:
• If a rectangle, rounded rectangle, ellipse, bitmap, visualization, button or a meta file is currently
selected, then next to the text "Rectangle (x1, y1, x2, y2)" there are four edit fields, where the
actual x/y positions are shown and can be modified.
• If a line, polygon or a curve is currently selected, a table will be available showing the actual XPosition and Y-Position of each of the black squares which mark the shape of the element, as
soon as it is selected. These values can be edited here.
The CoDeSys Visualization
2-9
2 - The Visualization Editor in CoDeSys
To set the modified position values in the elements list and in the visualization, press button Set
rectangle (in case 1.) resp. Set polygon (in case 2.).
Use the Delete button to remove selected visualization elements.
Use the Undo and Redo buttons to undo or restore changes that have been made just as you would
do with the commands 'Edit' 'Undo' and 'Edit' 'Redo' . In the dialog box, you can observe the changes
that are being made.
Click on OK to close the dialog box and confirm the changes.
Use Configure to get the configuration dialog for the element.
Status Bar in the Visualization
If a visualization has the focus, the current X and Y position of the mouse cursor in pixels relative to
the upper left corner of the image is displayed in the status bar. If the mouse pointer is located on an
Element, or if the element is being processed, then the number of the element will be displayed. If
you have selected an element to insert, then this element will also appear (for example, Rectangle).
2.4
Visualization, Configure - Overview
When configuring a visualization you have to distinguish between the configuration a particular
graphic element and the visualization object as a whole. Correspondingly a different selection of
configuration dialogs will be available, which can be opened by the command 'Configure' from Menu
'Extras' resp. from the context menu.
Placeholders
At each location in the configuration dialog where variables or text are entered, a placeholder can be
set in place of the respective variable or text. This makes sense if the visualization object is not to be
used directly in the program, but is created to be inserted in other visualization objects as an
"instance". When configuring such an Instance, the placeholders can be replaced with variable
names or with text.
See chapter 2.7 for the placeholder concept.
2.4.1
Visualization Elements, Configure...
In the configuration dialogs opened via the 'Extras' 'Configure' command the properties of an element
or object are set either by activating options or dynamically by inserting project variables. Besides that
the properties can be programmed via the components of a structure variable, which can be defined
for each visualization element.
Regard the order of analysis, which will be followed in online mode:
- The values which are given dynamically, i.e. via project variables, will overwrite the fix
parameters defined for the same property.
- If an element property is defined by a "normal" project variable as well as by the component of a
structure variable, then in online mode primarily the value of the project variable will be
regarded.
Please regard the possibility of using Placeholders as well as the special input possibilities which are
useful if the visualization should be used in CoDeSys HMI resp. as Target or Web-visualization, that
means if the visualization serves as the only user interface for a PLC program (see also: INTERN in
category 'Input' of the configuration dialogs, Keyboard usage)
'Extras' 'Configure'
With this command, the 'Configure element' dialog opens for configuring the selected visualization
element (see Select visualization element). You are given the dialog box when you double-click on the
element.
2-10
The CoDeSys Visualization
2 - The Visualization Editor in CoDeSys
Select a category in the left area of the dialog box (available categories depending on element type)
and fill out the requested information in the right area. This has to be done by activating options resp.
by inserting the name of valid variables, whose values should define the property of the element.
Note:
Note:
There are also configuration dialogs available for a group of elements. Regard that the settings will
be valid for the "element" group. If you want to configure the particular elements of the group, you
have to resolve the group.
If you have defined an element property by a "static" setting as well as dynamically by a variable,
then in online mode the variable will overwrite the static value (Example: "Alarm color Inside" can be
defined statically in category 'Color' and additionally dynamically in category 'Colorvariables' by a
variable). If the setting is controlled by a "normal" project variable as well as by a structure variable,
then the value of structure variable also will be overwritten by the "normal" project variable.
Please regard: Meter, Bar Display and Histogram must be re-grouped before !
At locations in the element configuration where variables are operative, the following Entries are
possible:
• Variable names, for which input assistant is available
• Expressions which are assembled from component accesses, field accesses with constant index,
variables and direct addresses.
• Operators and constants, which can be combined at will with the aforementioned expressions.
• Placeholders instead of variable names or text strings
Examples of permissible expressions:
x+y
100*PLC_PRG.a
TRUE
NOT PLC_PRG.b
9*sin(x + 100)+cos(y+100)
Function calls are not possible. Invalid expressions result in an error message on login („Invalid Watch
expression..."). Examples of invalid expressions: fun(88), a := 9, RETURN.
There are two possible ways in the configuration dialogs to write global variables: „.globvar" and
„globvar" are equivalent. The style with a dot (which is that used in the Watch- and Receipt Manager)
is not allowed within an assembled expression, however.
Regard also the possibility of using Placeholders (Chapter 2.4.1).
Angle
In the configuration dialog 'Configure Pie' in the Angle category you can each enter a value or a
variable defining the start angle and the end angle of the sector element in degrees. The sector will
be drawn clockwise from the start angle position to the end angle position.
Example:
Enter start angle: "90", end angle: "180"

Enter the text in the Content field. With the key combination <Ctrl>+<Enter> you can insert line
breaks, with <Ctrl>+<Tab>, tab stops. Besides the input of a pure text string you can use the following
formatting sequences:
• If you include "%s "into the text, then this location, in Online mode, will be replaced by the value of
the variable from the Text Output field of the Variables category. You also can use a formatting
string, which conforms with the standard C-library function 'sprintf':
Character
Argument / Output as
d,i
Decimal number
o
Unsigned octal number (without leading zero)
x
Unsigned hexadecimal number (without leading 0x)
u
Unsigned decimal number
c
Single character
s
String
f
REAL-values [-]m.<accuracy>; plus- resp. minus-sign defines right
(default) resp. left alignment; m defines minimal number of places to
be displayed; accuracy defines the number of places behind the
comma (default: 6).
Attention: If you want to get displayed a percent sign % combined with one of the formatting strings
mentioned above, you must be entered "%%". For example: Enter "Rate in %%: %s" to get
displayed in online mode "Rate in %: 12" (if the text display variable currently is "12").
The value of the variable will be displayed correspondingly in online mode. You can enter any
IEC-conforming format strings, which fit to the type of the used variable.
Attention: It is not checked whether the type which is used in the formatting string matches with the
type of the variable which is defined in the 'Text Output' field!
Example:
Input in the 'Content' field:
Fill level %2.5f mm
Input of a REAL variable in the 'Text Output' field, e.g.:
fvar1
Î Output in online mode e.g.: Fill level 32.8999 mm
• If you enter "%t ", followed by a certain sequence of special placeholders, then this location will be
replaced in Online mode by the system time. The placeholders define the display format, see the
following table. Attention: Do not insert any other characters before %t in the 'Content' field (in
contrast this is allowed for e.g. "%s", see above)

%Today is %d.%m.%y
-> Display in online mode: Today is 28.08.02
Note:
If a text string is to be transferred into a translation file, which will then be used in
Online mode to enable switching into another national language, it must be delimited
at the beginning and end by #.
Examples: "#Pump 1#" or else even "#Pump# 1"
The second case might for example, in the event of multiple occurrences of the text
Pump (Pump 1, Pump 2, etc.), prevent multiple appearances in the translation.
• If you include" %<PREFIX>" into the text, you can enter instead of "PREFIX" a certain string, which
will serve as an identifier concerning the use of dynamic texts. The prefix will be used together with
an ID number, which is to be defined in the 'Variables' category of the configuration dialog in field
'Textdisplay'. The combination references to a certain text, which is contained in a xml-file listing all
possible dynamic texts. Thus at run time the text which is indicated by the current ID-Prefixcombination will be displayed. For further information see also the description of 'Settings',
category Language.
The configured text will appear online in the prescribed alignment within the element: horizontally
left, center or right and vertically top, center or bottom.
If you use the Font button, a dialog box for selection of the font will appear. Select the desired font
and confirm the dialog with OK. With the Standard-Font button you can set the font that is selected in
the project options ('Project' 'Options' 'Editor'). If the font is changed there, then this font will be
displayed in all elements except in those elements for which another font has explicitly been selected
by using the Font button.

Motion absolute
In the visualization element configuration dialog box, in the Motion absolute category, X- or Y-Offset
fields variables can be entered. These variables can shift the element in the X or the Y direction,
depending on the respective variable value. A variable in the Scale field will change the size of the
element linear to its current value. This value, which is used as scaling factor, will be divided by 1000
implicitely, so that it is not necessary to use REAL-variables in order to get a reduction of the element.
The scaling always will refer to the balance point.
A variable in the Angle field causes the element to turn on its turning point, depending on the value of
the variable. (Positive Value = Mathematic Positive = Clockwise). The value is evaluated in degrees.
With polygons, every point rotates; in other words, the polygon turns. With all other elements, the
element rotates, in such a way, that the upper edge always remains on top.
The turning point appears after a single click on the element, and is displayed as a small black circle
with a white cross (
Note:

). You can drag the turning point with a pressed left mouse button.
In online mode the variables which are set in the 'Motion absolute' dialog will override the values of
structure components which additionally might be used to define the same property
('Programability').

Motion relative
In the dialog for configuring visualization elements in the Motion Relative category, you can assign
variables to the individual element edges. Depending on the values of the variables, the
corresponding element edges are then moved. The easiest way to enter variables into the fields is to
use the Input Assistant (<F2>).
The four entries indicate the four sides of your element. The base position of the corners is always at
zero. A new value in the variables, in the corresponding column, shifts the boundary in pixels around
this value. Therefore, the variables that are entered ought to be INT variables.
Note:
Positive values shift the horizontal edges downward, or, the vertical edges, to the right!
Note:
In online mode the variables which are set in the 'Motion absolute' dialog will override the values of
structure components which additionally might be used to define the same property
('Programmability').

You can enter Boolean variables in the Invisible and Change color fields. The values in the fields
determine their actions. If the variable of the Invisible field contains the value FALSE, the
visualization element will be visible. If the variable contains the value TRUE, the element will be
invisible.
Disable input: If the variable entered here is TRUE, all settings of category 'Input' will be ignored.
Change color: If the variable which is defined in this field, has the value FALSE, the visualization
element will be displayed in its default color. If the variable is TRUE, the element will be displayed in
its alarm color.
Textdisplay:
o If you have inserted a "%s" in the Content field of the Text category or if you have included
"%s" in the textstring, then the value of the variable which is defined in 'Textdisplay' will be
displayed in online mode in the visualization object. "%s" will be replaced by the value.
o If you have inserted resp. included a "%<PREFIX>" in the Content field of the Text category
("PREFIX" must be a sequence of letters), then the variable resp. the numeric value which is
entered here in 'Textdisplay' will be interpreted as an ID, which in combination with the prefix
serves as a reference on a text, which is described in a XML-file. This text will be displayed in
online mode instead of "%<PREFIX>" in the visualization object. Thus a dynamic modification
of the text display is possible. See further information in the description of the dialog 'Settings',
category Language.
o If you want to edit the value of the variable in Online mode using the keyboard, you can do this
via the 'Text input of variable' 'Textdisplay' in the Input category.

Input
Dialog for configuring the visualization elements (Category Input)
Toggle variable: If this option is activated, in online mode you will toggle the value of the variables
which are located in the input field by each mouse click on the visualization element. You can obtain
input assistance for data entry via <F2>. The value of the Boolean variable changes with each mouse
click from TRUE to FALSE and then back to TRUE again at the next mouse click, etc.
Tap Variable: If this option is activated, in online mode you can switch the value of the Boolean
variable which is located in the input field, between TRUE and FALSE. Place the mouse cursor on the
element, press the mouse-key and hold it depressed. If option Tap FALSE is activated, the value is
set to FALSE as soon as the mouse key is pressed, otherwise it is set to TRUE at this moment. The
variable changes back to its initial value as soon as you release the mouse key.
Zoom to Vis...: If this option is activated, you can enter in the edit field the name of a visualization
object of the same project to which you want to jump by a mouse-click on the element in online mode.
In this case always first the window of the target visualization will be opened before that of the current
one will be closed.
The following entries are allowed:
• The name of a visualization object of the current project (see Object Organizer)
• If a visualization instance that contains placeholders is to be jumped to, the placeholders can be
directly replaced by variable names or text when called up. For this purpose, conform to the
following syntax:
<Visuname>(<Placeholder1>:=<Text1>, <Placeholder2>:=<Text2>,..., <Placeholder n>:=<Textn>).
During compilation of the visualization it will be checked, whether the text matches with one of the
defined replacement values defined in the placeholder list, if it does not, a warning will be output.
Example:
Calling the visualization visu1, whereby the placeholders $var_ref1$ and $var_ref2$ used in visu1 are
replaced by the variables PLC_PRG.var1 and PROG.var1 respectively:
visu1(var_ref1:=PLC_PRG.var1, var_ref2:=PROG.var1)
• If a program variable of the type STRING (e.g. PLC_PRG.xxx) has been entered instead of a
visualization object, then this variable can be used to define the name of the visualization object
(e.g. ,visu1') which the system should change to when a mouse click occurs (e.g. xxx:= ,visu1).
• If you issue the command „ZOOMTOCALLER" in the Zoom to vis. field, a backward jump into the
calling visualization is achieved in Online mode by a mouse click on the element, if such a
constellation was configured.
Note:
The implicit variable CurrentVisu (type STRING, for implicit (system) variables see here) describes
the name of the currently opened visualization object. For example it can be used in the application to

control which visualization should be opened resp. to see which is the currently opened. But this will
only work if the names of the visualization objects are defined in capital letters (see 'Create a
visualization object'). Example: CurrentVisu:='PLC_VISU';
Execute program: If this option is activated you can enter ASSIGN- or special "INTERN"-commands
in the input field, which will be executed in online mode as soon as you perform a mouse-click on the
element. Press button "..." to get the dialog Configure programs where you can select the desired
commands (Add) and arrange them in the desired order (Before, After).
Note:
This feature especially is important if the visualization will be the only operating interface of a system
(pure operating version). See a description of the commands: Special input possibilities for the
CoDeSys operating version.
If you select the Text input of variable 'Textdisplay', then in Online mode you will get the possibility
to enter an value in this visualization element which will upon pressing <Enter> be written to the
variable that appears in the Textdisplay field of the Variables category.
Select in the scroll box which kind of input should be possible later in online mode. Text: An edit field
will open, where you can enter the value. Numpad resp. Keypad: A window will open showing an
image of the numeric resp. alphabetic keypad, where you can enter a value by activating the
appropriate key elements. This might be useful if the visualization must be operatable via a touch
screen. The range of valid input values can be restricted by defining a minimum and a maximum value
in the edit fields Min: and Max:.
ToolTip
The dialog Text for Tooltip offers an input field for text which appears in a text field as soon as the
mouse cursor is passed over the object in online mode. The text can be formatted with line breaks by
using the key combination <Ctrl> + <Enter>.
Security
It might be useful that different user groups get different operating possibilities and display of a
visualization. This can be reached by assigning different access rights concerning particular
visualization elements. You can do this for the eight user groups which are available in CoDeSys (see
also 'Project' 'Object' 'Properties' resp. 'Project' 'User Group Passwords'). The access rights can be
assigned by activating the appropriate option in the configuration dialog 'Access rights' for a
visualization element:

If you want to assign the access rights also to all other elements of the visualization object, activate
option Apply to all visual elements.
Note:
Please regard, that the access rights which are set for the visualization object in the 'Project' 'Object'
'Properties' dialog, are independent on those of the particular visualization elements !
Programability
The properties of a visualization element can not only be defined by a static setting or by a "normal"
project variable, but also by the components of a structure variable, which is exclusively used for
programming visualization elements.
For this purpose the structure VisualObjectType is available in the library SysLibVisu.lib. Its
components can be used to define most of the element properties.
Note:
In case of multiple definition of a element property the value of the "normal" project variables will
overwrite that of the structure variable and both will overwrite a static definition.
In order to configure the element properties by using a structure variable, do the following:
Open the configuration dialog, category 'Programmability' and enter a new, unique (!) variable name in
the field Object Name:. For this purpose you must activate the option by a mouse-click in the
checkbox. The variable automatically will be declared with type VisualObjectType, a structure which
is contained in the library SysLibVisu.Lib. The declaration is done implicitly and not visible for the
user. Make sure that the library is included in the library manager.
After the next compile the newly assigned structure variable will be available in the project. (Hint:
Activate the Intellisense functionality 'List components' in the project options, category Editor, in order
to get the structure components in a selection list as soon as the variable name followed by a dot is
entered).
Example: If you have defined a Object Name "visu1_line" for a visualization element, then you can
program the line width of this element by e.g. "visu1_line.nLIneWidth:=4".

As soon as a table is inserted for the purpose of visualization of an array, the dialog Configure Table
will be opened. Besides the categories 'Tooltip' and 'Security' which are also available for other
visualization elements, the following categories will be available for configuring display and contents of
the table:
Category Table:
Dialog for the configuration of a Table, Category Table
Do the following table settings:
Data array: Insert the name of an array which should be visualized in the table. It is recommended to
use the input assistant (<F2>) resp. the Intellisense function.
Column header, Line header: Activate these options if you want to get displayed the titles in the
table. The line title reflects the array index (first column of the table), the column title can be defined in
category 'Columns'.
2-26

Category Columns:
Dialog for the configuration of a Table, Category Columns
Here you define the table elements. In the left window you get al list of all elements, which are
handled in the array per index. In case of an array of a structure these would be the structure
components.
Using the arrow button > you can transfer a selected component from the left window to the right
window where you define the set of elements to be displayed in the table. Pressing button >> all
elements will be transferred at a single blow. In the same manner you can remove elements from an
already defined set (<, <<). In order to modify the default settings concerning the display of the table
column for one of the elements, perform a double-click on the desired entry in the right part of the
window, or press button '...' to open the dialog 'Configure columns':
Dialog for Configuring a Table, Category Columns, Column Properties
Editing the column header and the column width:
Initially the edit field Column header will contain an automatically created title (e.g.
"PLC_PRG.arr1[INDEX].iNo" in case of an array of structure. for the column representing the structure
component "iNo"). which you can change Further on the Column width (number of characters) can
be set.
Editing configuration parameters for all elements of a column:
By default the table fields are displayed as simple rectangles and the entries are not editable. If you
however activate the option Use template, a pre-defined set of parameters can be used, e.g. for the
line width, the text input possibilities etc. To edit these parameters the common configuration dialogs
as know for rectangles, bitmaps, buttons etc. are available, which you can access by a mouse-click on
the button Edit template.
In order to define online actions for all entries of a column, i.e. for all array-elements of one array
dimension, use the placeholder [INDEX] when entering the array name in the configuration dialogs
(e.g. PLC_PRG.arr1[INDEX] like used in the default column header).

Select only columns: The whole column will be selected.
Select rows and columns: The whole column and line will be selected.
Frame around selected cells: A selected cell gets surrounded by a frame.
Variable for selection X, Variable for selection Y: Here you each can enter a project variable, which
will indicate the X- resp. Y-Index of the selected table cell.
Example: Create a table element visualizing the array of a structure:
Define the following structure:
TYPE strucTab :
STRUCT
iNo: INT;
bDigi : BOOL;
sText:STRING;
byDummy: BYTE;
END_STRUCT
END_TYPE
In PLC_PRG define the following array:
arr1:ARRAY [1..5] OF strucTab;
and the following variables:
selX:INT;
selY:INT;
Create a visualization object and insert a table element. Configure like follows::
Cat. Table: data array: "PLC_PRG.arr1"
Cat. Columns: (Close the dialog which will open with YES) – Transfer the components iNo, bDigi, sText to the right window In the right window perform a double-click on the first entry (PLC_PRG.arr1[INDEX].iNo) and in the dialog which will open,
replace the default title by "Number". Confirm with OK and also define new column titles for the other two entries (e.g. "Value"
and "Text"). – In category 'Spec.Table' enter at 'Variable Selection X': "PLC_PRG.selX" and at Variable Selection "Y:
PLC_PRG.selY". Activate option 'Frame around selected cells'. Press button 'Selection color' and choose color 'yellow'. Close
the configuration dialog with OK. The table element now should be displayed as shown in the following:
At the left border the numbers of the array index, at the top the titles of the selected structure components. You
can modify the column widths by placing the cursor on the separator between two columns and moving the
mouse as soon as the cursor appears as a horizontal double-arrow. .
In online mode the current values of the array elements will be displayed in the table cells. As soon as you
select a table cell by a mouse-click, it will get yellow-colored and surrounded by a frame. Example:

ActiveX-Element
The ActiveX-Element serves for displaying a passive ActiveX Control within a visualization. The
element is usable on Windows32 based systems in CoDeSys HMI and in the CoDeSys TargetVisualization.
The configuration dialog is opened by a double-click on the inserted element and offers three subdialogs, for selecting the control type, for defining method calls and for the configuration of the display:
Category Control:
Dialog Configure ActiveX-Element, Category Control
In this dialog you can mark the desired ActiveX Control in the selection list offering all ActiveX
Controls which are registered on your computer.
Category Methodcalls:
Here you configure the method calls for the chosen ActiveX Control:
Dialog Configure ActiveX-Element, Category Methodcalls

The CoDeSys Visualization
2 - The Visualization Editor in CoDeSys
Webbrowser:
These input fields only can be edited if you are configuring a control element which
supports the IWebBrowser interface (e.g. Internet Explorer or Mozilla Browser). In this
case CoDeSys can directly call the method Navigate (other method calls must be
controlled via a user defined Dll, see below 'Additional Call').
Enter an URL as a parameter value in field Variable for URL(Input as a string between
inverted commas) resp. a project variable of type STRING defining an URL. The
browser will be called as soon as the variable entered in field Condition for call gets
TRUE (rising edge). If no call condition is defined here, in the Target-Visualization the
browser will be called in each cycle of the visualization task!
Additional Call:
Via a user defined Windows-Dll you can define method calls for the ActiveX Control in
order to control the behaviour of the control at a call. For this purpose you must enter
the path of the Dll in the field at Dll for Call. If you press the button you get the dialog
for opening a file where you can browse for a Dll. If the file is in the visualization files
directory as defined in the project options, only the file name will be entered, otherwise
the complete file path.
Attention: If the Dll is to be used on a runtime system with a Target-Visualization, it must
explicitly be copied there. When the Control is called in the Target-Visualization, only
the filename contained in the path will be regarded.
The Dll is called as soon as the variable defined below in Condition for call gets TRUE
(rising edge). If no condition is specified, in the Target-Visualization it will be called in
each cycle of the visualization task!
Regard the following when creating an appropriate Dll:
The Dll must export a method "ExecuteActiveXCall" with this function prototype:
void ExecuteActiveXCall(IUnknown* pUnk, char* pszId, char* pszParam,
char* pszReturnBuffer, int nReturnBufferSize, DWORD* pdwReturnFlag);
The function will be called with the following parameters which can be defined in the
configuration dialog:
pszId:
string resp. string variable specified in field Methodidentification
pszParam:
value specified in field Parameter
The parameter pUnk allows a query of further Com(ActiveX-)interfaces. With these
interfaces you can call any Method on your ActiveX-Control with any parameters
packed in a string!
The parameters pszReturnBuffer, nReturnBufferSize and pdwReturnFlag currently are
not used.
For an example of a Dll source file see Appendix B.
Category Display:
In this dialog you can specify the variables defining the position (X-Offset, Y-Offset, see

2. Variable PLC_PRG.n, red line, Marker: PLC_PRG_TRD.rSlider2
Curve configuration: Straight line, no tolerance band
Configuration of two display fields for the current record values provided by the marker variables:
Rectangle element 1: Category Text: insert "%s" in the Content field; Category Variables: insert in field
Textdisplay: PLC_PRG.rSlider1
Rectangle element 2: Category Text: insert "%s" in the Content field; Category Variables: insert in field
Textdisplay: PLC_PRG.rSlider2
(additionally insert a rectangle element at the left border of the rectangle elements 1 and 2, showing the
curve color of the corresponding record variable)
Result in online mode after login and start of the program:
The record is running from the left to the right; the latest value is shown on the leftmost position; every 200
milliseconds the current value will be added to the display. The arrow buttons in the symbol bars allow shifting
the displayed time range. Using the simple arrow buttons you can shift step by step, using the double arrows
you get to the end resp. start of the record. For example: if you go to the start of the record by pressing the
double arrows pointing to the left, you get a still display of the former values. If you then move the marker (grey
triangle in the upper left corner) along the time axis, you can read the exact values of each of the both recorded
variables for each time in the rectangle elements below the diagram.
Bitmap
You can enter the options for a bitmap in the Bitmap category within the visualization element
configuration dialog box.
Enter the bitmap file and its path in the Bitmap field. You can use the ... button to open the standard
Windows Browse dialog box from which you can select the desired bitmap.
The following entries affect the frame of the bitmap.
By selecting Anisotropic, Isotropic or Fixed you specify how the bitmap should react to changes in
the size of the frame. Anisotropic means that the bitmap remains the same size as the frame which
allows you to change the height and width of the bitmap independently. Isotropic means that the
bitmap retains the same proportions even if the overall size is changed (i.e., the relationship between
2-44
The CoDeSys Visualization
2 - The Visualization Editor in CoDeSys
height and width is maintained). If Fixed is selected, the original size of the bitmap will be maintained
regardless of the size of the frame.
If the Clip option is selected together with the Fixed setting, only that portion of the bitmap that is
contained within the frame will be displayed.
If you select the Draw option, the frame will be displayed in the color selected in the Color and Alarm
color buttons in the color dialog boxes. The alarm color will only be used if the variable in the Change
Color field in the Variable category is TRUE.
In the selection list in the lower part of the dialog you can define whether the bitmap should be
inserted in the project (Insert) or whether just a link to an external bitmap-file (path as entered above
in the 'Bitmap' field) should be created (Link to file). It is reasonable to keep the bitmap file in the
project directory, because then you can enter a relative path. Otherwise you would enter an absolute
path and this might cause problems in case you want to transfer the project to another working
environment.
Visualization Element Configuration Dialog Box (Bitmap Category)
Visualization
When you insert a visualization as an element in another visualization, you are creating an "instance"
(reference) of the visualization.
The configuration of this instance can be done in the Visualization category within the visualization
element configuration dialog box.
Enter the object name for the visualization, which should be inserted, in the Visualization field. Use
the ... button to open a dialog box containing the visualizations available in this project. Any
visualization may be used with the exception of the current one.
The possible settings concerning the visualization frame are the same as described for a bitmap (see
above).
The Placeholder button leads to the 'Replace placeholder' dialog. It lists in the 'Placeholder' column
all the placeholders which had been inserted in the configuration dialogs of the "mother"-visualization
and offers in the 'Replacements' column the possibility of replacing these for the current instance with
a definite value. Which replacements are possible in a given case depends on whether a value group
was predefined in the 'Extras' 'Placeholder list' dialog in the "mother"-visualization. If this is the case, it
will be displayed in a combo box for selection. If nothing was pre-defined, double clicking on the
corresponding field in the Replacements column opens an editing field which can be filled in as
desired.
The CoDeSys Visualization
2-45
2 - The Visualization Editor in CoDeSys
Visualization Element Configuration Dialog Box ( Visualization Category)
A further possibility for replacing placeholders in instances occurs directly when you define the call of
visualization by an entry into the Zoom to vis. option field in the configuration dialog ('Input' category).
Note:
Note:
No control of the chronological sequence of replacements is possible! Therefore no placeholders
should be replaced with text that also contains placeholders!
When using placeholders it is no longer possible to check for invalid entries in the configuration of the
visualization element immediately upon compilation of the project. Hence the appropriate error
messages are first issued in Online mode (...Invalid Watch expression..).
Example of an application of the placeholder concept:
Instances of a function block can easily be displayed with the help of instances of the same visualization. For
example, in configuring the visualization visu, which visualizes the variables of function block, one could begin
each variable entry with the placeholder $FUB$ (e.g. $FUB$.a). If an instance of visu is then used (by inserting
visu in another visualization or by calling via 'Zoom to vis.'), then in the configuration of this instance the
placeholder $FUB$ can then be replaced with the name of the function block instance to be visualized.
This might look like shown in the following:
In the project define a function block containing the following declarations:
FUNCTION_BLOCK fu
VAR_INPUT
changecol : BOOL; (* should cause a color change in the visualization *`)
END_VAR
In PLC_PRG define two instances of 'fu':
inst1_fu : fu;
inst2_fu : fu;
Create a visualization object 'visu'. Insert an element and open the configuration dialog, category 'Variables'.
Enter in field 'Change color' the following: "$FUB$.changecol". Open category 'Input' and enter in field 'Tap
Variable' "$FUB$.changecol". Open category 'Text' and enter"$FUB$ - change color ".
Create another visualization object 'visu1'.
Insert visualization 'visu' twice in 'visu1' (two instances of 'visu').
Mark the first instance of 'visu' and open the configuration dialog of category 'Visualization'. Press button
'Placeholder', so that the placeholder list will be displayed. There replace entry 'FUB' by 'PLC_PRG.inst_1'.
Now mark the second instance of 'visu' and (like described for the first one) replace 'FUB' by 'PLC_PRG.inst_2'.
Now in online mode the values of the variables which are used to configure the two instances of 'fu' will be
visualized in the corresponding instance of 'visu'.
Of course the placeholder $FUB$ can be used at all places in the configuration of 'visu' where variables or text
strings are entered.

The CoDeSys Visualization
2 - The Visualization Editor in CoDeSys
Attention: Online behaviour of a visualization instance: If you insert a visualization and then select and
configure this instance, it will be regarded as a single object and in online mode will react to inputs
correspondingly to its configuration. In contrast: if you do not configure the instance, then in online
mode its particular visualization elements will react exactly like those of the original visualization.
Special input possibilities for operating versions
The CoDeSys visualization can target specifically be used with CoDeSys HMI or as Web- or TargetVisualization as a mere operating interface. Then no menus and status and tool bars will be available
to the user and no possibility to modify the code.
Thus, when a visualization is created with CoDeSys for the purpose of being used as a 'operating
version' the principal control and monitoring functions in a project must be assigned to visualization
elements thus making them accessible via mouse click or keyboard in Online mode.
See in the following some special input possibilities to configure visualization elements for the purpose
of being used in CoDeSys HMI. They are available in the configuration dialog for a visualization
element:
Enter internal commands in the field Execute program in the category Input according to the
following syntax (The dialog 'Configure Programs' is available for this purpose):
INTERN <COMMAND> [PARAMETER]*
The following table shows the available internal commands. Some of them expect to receive several
parameters, which are then entered separated by spaces. Optional parameters are enclosed in
square brackets. For those commands which require that a Watch list be specified, a placeholder can
be used instead of the direct name. If you enter several commands for one element, these are
separated by commas.

When this command is used, a dialog box will open in which you can make certain settings that affect
the visualization.
Note: The categories Display, Frame and Language also can be edited in the online mode.

Setting dialog for visualizations (Category Display)
Category Frame: If Auto-scrolling is selected, the visible portion of the visualization window will move
automatically when you reach the edge while drawing or moving a visualization element. If Best fit in
Online mode is selected, the entire visualization including all elements will be shown in the window in
Online mode regardless of the size of the window. When Include Background Bitmap is selected,
the background bitmap will be fitted into the window as well, otherwise only the elements will be
considered.
Category Grid: Define here whether the grid points are visible in the offline mode, whereby the
spacing between the visible points is at least 10 even if the entered size is smaller than that. In this
case the grid points only appear with a spacing which is a multiple of the entered size. If Active is set,
the elements will be placed on the snap grid points when they are drawn and moved. The spacing of
the grid points is set in the field Size.
Category Language: Here you can specify in which national language the text that you assigned to an
element in the Text and Text for Tooltip options should be displayed. Additionally the option
'Dynamic Texts' allows a dynamic change of the displayed text.
Note: The text display changes only in Online mode!
For a non-dynamic switch of the used language a language file can be used (project translation file
*.tlt or *.txt, resp. a special visualization language file *vis).
Alternatively dynamic texts can be used. Those allow switching between different text version in the
display of a visualization element, inclusively the change of language.
Language file:
In order to select a translation or language file, activate the Language file option in the dialog
and enter in the input field next to it the appropriate file path, or obtain the help of the standard
file opening dialog via the
button.
In the selection window under Language you can now select among the options German and
English in the example shown here.
Regarding creating a translation file *.tlt, please see 'Project' 'Translate into other languages'
(User Manual for CoDeSys).

Dialog for selection of a language file for a visualization
For creating a special language file *.vis for the visualization, see here (This option is retained
for reasons of compatibility with projects created under Version 2.1.):
Creating a *.vis language file:
In order to set up a new *.vis language file for the visualization, proceed as follows:
Open likewise the Settings Visualization dialog, Language category. Choose option
language file. In the associate input field enter where you want to store the file. The
extension is .vis. You also can use the dialog 'Open file' by pressing the button. If a
language file with the extension .vis is already present, it will be offered to you here.
In the input field next to Language you fill in a keyword for the language which is
currently used in the visualization, i.e."german" (or "D") then press the button Save. A
file with the extension .vis will be created, which now can be edited by a normal text
editor. For example you can open the file by NOTEPAD:
Example of a language file for a visualisation (Category Language)
You get a list of the text variables for the language currently used in the visualization. It
includes a reference to the title of this list, for example "1=german" as reference to the
title [german]. You can extend the list by copying all lines, then replacing the German by
The CoDeSys Visualization
2-51
2 - The Visualization Editor in CoDeSys
English text and setting a new title [english]. Beyond the line 1=german you accordingly
have to add 2=english.
To view the visualization in one of the prepared languages, open the dialog Language
again. In the option field beyond Language now you can choose between german and
english (for the example described above).
Dynamic texts:
Dynamic texts allow switching between different text versions for a visualization elements. The
text version is controlled by a Prefix-ID-combination, which is assigned to the text in a XML-file
and which can be defined by a project variable (see Chapter 2.5).
'Extras' 'Select Background Bitmap'
Use this command to open the dialog box for selecting files. Select a file with the extension "*.bmp".
The selected bitmap will then appear as the background in your visualization.
The bitmap can be removed with the command 'Extras' 'Clear Background Bitmap'.
'Extras' 'Clear Background Bitmap'
Use this command to remove the bitmap as the background for the current visualization.
You can use the command 'Extras' 'Select Background Bitmap' to select a bitmap for the current
visualization.
'Extras' 'Keyboard usage'
The use of hotkeys can optimize the pure keyboard operation of a visualization.
In the configuration of a visualization object you can define hotkeys which will cause actions like
visualization elements do. For example you could define that – if visualization 'xy' is active – in online
mode the hotkey <Strg><F2> will stop the program, which also will happen as soon as element 'z' of
visu 'xy' gets an input (by mouse-click or via touch screen).
Anyway per default the keys <Tabulator> <Space> <Enter> will work in that way that in online mode
each element of a visualization can be selected and activated.
The dialog 'Keyboard usage: set possible keystrokes' can be called in the menu 'Extras' or in the

Master layout
The usage of a "Master layout" in visualizations for example could be used to provide a dialog in
various visualizations without the need to explicitly insert it in each of them. Whether and when the
dialog will be displayed in online mode could be controlled via a variable which is defined in the
master layout configuration for the visibility of the dialog elements.
Use as master layout
If a visualization is defined as "Master layout", it will be inserted automatically in all other visualizations
(if those are not explicitly excluded, see below) and will be available there with all its functions during
online mode. It always will be inserted on the front level and cannot be edited there. Modifications of
the configuration only can be done in the master layout visualization itself.
Appointing a visualization to be the Master layout is done in the Properties dialog, which can be
opened for an object currently selected in the Object Organizer via command 'Project' 'Object'
'Properties' (see CoDeSys User Manual, Chapter 4.3). Option Master layout must be activated for this
purpose. If prior to this another visualization has been defined to be a master layout, that one will
automatically be re-defined to be a "normal" visualization (option Visualization in the Properties dialog.
Visualization wihtout master layout
Also in the Properties dialog of a visualization object you can define that it should be used as a
Visualization without master layout.

Use as Web- or Target-Visualization
If a project is created for a Web- or Target-Visualization (see Chapter ??? resp. ???), for each
visualization object you can define whether it should be used for this purpose or not.
Thereto select the visualization object in the Object Organizer and open the Properties dialog
('Project' Object' 'Properties', see CoDeSys User Manual, Chapter 4.3). If in the Target Settings the
options Web- resp. Target-Visualization are activated, in the Properties dialog the corresponding
options Use as Web-Visualization resp. as Target-Visualization automatically also will be activated. In
order to explicitly exclude the object from the use in a Web- or Target-Visualization deactivate the
appropriate option.
2.5
Dynamic Texts
2.5.1
Configuration
You can control dynamically which text will be displayed in a visualization element in online mode by
using prefix-ID-combinations, each pointing to another text defined in a XML-file. Prefix and ID must
be defined in the configuration dialogs of the visualization element, where the ID can be dynamically
defined by using a project variable. The XML-file describing the assignment to a text, must be linked
to the project. (see Chapter 2.5.2, XML-File for dynamic texts). This is done in the visualization
settings dialog. The XML-file must have a certain format, the particular texts are listed below the
according Prefix-ID-combination and a language code is added. Thus the text display not only can
switch between different contents but also between different languages. The desired language can be
selected as described above for the Language file in the 'Settings' dialog, category 'Language':
So in order to get a dynamic text display, the following entries have to be made in the different
configuration dialogs of a visualization:
1. Link the XML-file(s): Dialog 'Settings' category Language:
Activate option Dynamic texts and press button Add, in order to link one or several XML-files,
which are available on your system, to the project. The selected files will be listed in the window
below the button. Press button Delete if you want to remove a selected file from the list. If you
want to get displayed just those visualization elements, for which a dynamic text replacement is
done, then activate option Hide elements, if no text replacement took place.
Selecting one of the language identifiers offered in the selection list at field Language will cause
the display of those text versions (for the corresponding prefix-ID-combination) which are
marked with that language identifier in the XML.-file.
Configuration dialog Settings, category Language, for dynamic texts
The CoDeSys Visualization
2-55
2 - The Visualization Editor in CoDeSys
2. Define the ID in configuration dialog 'Variables' in field 'Textdisplay':
Enter here a value (number) resp. a project variable which should define the ID of a text
(as used in the XML-file).
3. Define the text format in configuration dialog 'Text':
In the Content field, insert a placeholder "%<PREFIX>" at that position of the text, where
you want to get displayed a dynamic text in online mode. Instead of "PREFIX" you can
enter any desired string. See the description for the 'Text' configuration dialog.
For each prefix-ID-combination, which is found in a linked XML-file, the assigned text will be
displayed in the visualization element in online mode. If no appropriate entry is found, no
replacement will be done.
2.5.2
XML-File for Dynamic Texts
For a description how to use dynamic texts in the visualization see chapter 2.5.1, 'Settings', category
Language. The underlying file must be available in XML format (<file name>.xml). In this file texts are
assigned to identifiers (which are a combination of a prefix and an ID), which can be entered in the
configuration of a visualization element. Besides that a default language can be defined in a header
section. See an example at the end of this chapter.
The descriptions in the xml-file are enclosed by tag <dynamic-text> and <\dynamic_text> which have
to be entered at the beginning resp. end of the file.
Please note: Primary formats of the xml-file, which do not use the <dynamic_text>\<\dynamic_text> tags or the
header section, will be supported further on !
The header section starts with <header> and is closed with <\header>. If you want to define a
default language, use entry <default-language>. A default font which is assigned to a certain
language, can be defined via entry <default-font>. These entries are optional. If they are missing, the
dynamic text in the visualization will be displayed according to the local configuration settings of the
visualization.
<header>
<default-language> <language> </defaultlanguage>
Default language; that means that if there is
no text entry available for the currently set
language, that text will be used which is
found within the same text entry for the
default language. If also for the default
language no text is found, "<PREFIX> <
ID>“ will be displayed. If multiple XML-files
are used, thus providing multiple headers,
only that header section will be regarded,
which is read at last. So it is reasonable to
use only one header section !
The
language token must correspond which one
of that used in the text entries (see below).
<default-font>
Default font for <language>: The given font
(e.g. "Arial" will automatically be used
for all elements, which display dynamic
texts in <language>. The language token
must correspond which one of that used in
the text entries (see below).
<language><language></language>

(e.g. "english"). This identifier then will be
displayed in the 'Settings' dialog, category
Language of the visualization element in
the selection list at 'Language'; instead of
"TEXT" insert any text which then will be
displayed instead of the above defined IDprefix-combination in the visualization
element.
</text>
For each prefix-ID-combination at least for 1 language a text entry must be available.
e.g. <deutsch> in the file example shown below will indicate the start of the german version of a text,
</deutsch> terminates the text.
Dynamic texts on the one hand can serve to display Texts in different languages, but of course on the
other hand they also can be used to change the content of a text (same language) display
dynamically.
Example: You want to have two visualization elements, one for visualizing the current machine identification,
the other for visualizing an error message according to a currently given error number:
(1) Define in PLC_PRG the following variables: ivar of type INT, defining the current machine identification;
errnum of type INT defining the current error number.
(2) Configure a visualization element for displaying the current machine identification:
a. Enter in category ‚Text’ in the text field: "%<Maschine>"
b. Enter in category ‚Variables’ at Textdisplay“: „PLC_PRG.ivar”
(3) Configure another visualization element for displaying the error message for the currently occurred error:
c. Enter in category ‚Text’ in the text field: "%<Error>"
d. Enter in category ‚Variables’ at Textdisplay“: "PLC_PRG.errnum“
(4) Create a xml-file, e.g. with name dynamictextsample.xml, according to the syntax described above, which
should look as follows for the current example:
<?xml version="1.0" encoding="ISO-8859-1"?>
<dynamic-text>

(7) In the visualization settings set language to "deutsch". Set PLC_PRG.ivar to "1" and PLC_PRG.errnum to
"4711". Now in the visualization elements the following texts should be displayed: "Vorschub" resp. "Fehler
an Position 4711". The texts will be displayed in Arial 13.
2-58

(8) Set PLC_PRG.ivar to „2“ and PLC_PRG.errnum to "2000". The texts will change to "Beschleunigung" and
"Das ist ein Fehlertext über mehrere Zeilen“.
(9) In the visualization settings change the language to "english". Now the following texts will be displayed:
"Acceleration" and "This is a error text over more than one line".
(The change of language also could be managed by using the INTERN command 'LANGUAGE' by another
visualization element.)
2.6
Calling up language-dependent Online Help via a visualization element
The calling of a different Help file with a visualization element can be tied in with the language
currently entered for the visualization. For this purpose, the command INTERN HELP must be entered
for this element in the 'Configure element' dialog at the location 'Execute program', and a [VisuHelpfiles] section must be present in the CoDeSys .ini-file. Below this, the corresponding help files
must be assigned to the languages available for selection in the visualization: e.g.:
[Visu-Helpfiles]
German=C:\PROGRAMME\HELP_D.HLP
English=C:\PROGRAMME\HELP_E.HLP
2.7
Placeholder Concept
At each location in the configuration dialog where variables or text are entered, a placeholder can be
set in place of the respective variable or text. This makes sense if the visualization object is not to be
used directly in the program, but is created to be inserted in other visualization objects as an
"instance". When configuring such an Instance, the placeholders can be replaced with variable
names or with text (see chapter 2.4.1, „Configuring an inserted visualization", there you also find an
example for using placeholders).
Any string enclosed in two dollar signs ($) is a valid placeholder (e.g. $variable1$, variable$x$). For
each placeholder a „value group" can be defined as an input specification in the 'Placeholder list'
dialog (called from 'Extras' 'Placeholder list'). With one of these values you can replace the
placeholder when configuring an instance of the visualization object. A placeholder list will be
available in the instance to do those replacements.
'Extras' 'List of Placeholders...'
This list is used at two places in CoDeSys: to manage placeholders and to configure them:
1. primarily you use the list when configuring a visualization object, which later should be inserted,
which means instanced, in other visualization(s). For this reason you will use placeholders instead
of or additionally to variables and strings in the configuration dialogs. You can open the dialog
'Placeholders' by the command 'List of Placeholders' in the 'Extras' menu or in the context menu.
The list shows three columns:
2. Column Placeholder will list all placeholders, which are currently used in the configuration of the
visualization object. Column Element number shows the elements which contain a placeholder. In
column Replacements you can enter one or several strings (text, variable, expression) which you
want to get available later when replacing a placeholder during the configuration of an instance of
the visualization object. The elements of the selection must be entered separated by commas. If no
or an impossible replacement string is specified, then the placeholder can be replaced with any
desired text later during the configuration of the visualization's instance.
The CoDeSys Visualization
2-59
2 - The Visualization Editor in CoDeSys
Placeholder list for input of possible replacements for the placeholders
3. later you use the list of placeholders when configuring an instance of the above mentioned
visualization object, that means after this object has been inserted (as an 'instance') in another
visualization by the command 'Insert' 'Visualization'. For this purpose do the following to open the
dialog: Select the inserted visualization, execute command 'Extras' 'Configure' and press button
'Placeholders' in Category 'Visualization'. In this case the dialog will only contain two columns:
List of placeholders for replacing a placeholder in a visualization instance
Column Placeholder – like described above – shows all placeholders which have been defined for
the primary visualization object. If additionally a selection of possible replacements had been
defined, this list will now be available in column 'Replacement'. Select one of the entries to replace
the placeholder in the present instance. If no replacements have been pre-defined then you can
manually enter an expression or variable. For this purpose perform a mouse-click on the field in
column Replacement to open an editor field.
2.8
Visualization in Online Mode...
Regard the following items concerning a visualization in online mode:
• Order of evaluation:
2-60
-
Dynamically defined element properties (by variables) will overwrite the (static) base settings
defined by options in the configuration dialogs.
-
If an element property is defined by a "normal" project variable as well as by the component of
a structure variable (Programmability), then primarily the value of the project variable will be
regarded.
The CoDeSys Visualization
2 - The Visualization Editor in CoDeSys
-
A visualization can be configured in that way that in online mode it can be operated solely by
inputs via keyboard. This is an important feature especially for using the visualization with
CoDeSys HMI, as Target- or as Web-Visualization.
• The configuration settings for Display, Frame and Language can also be edited in online mode.
• As long as a visualization "instance" is not configured explicitly, the particular elements of the
instance in online mode will react on inputs like those of the original visualization ("mother" of the
instances).
• When you switch the language ('Extras' 'Settings') this will only effect the display in online mode.
• A visualization can be printed in online mode.
Operation over the keyboard - in online mode
In order to get independent from the mouse or a touch screen, it is useful to configure a visualization
in a way that allows pure keyboard operation:
Per default the following key (combinations) will work in online mode anyway (no special configuration
necessary):
• Pressing the <Tabulator> key selects the first element in the element list for which an input is
configured. Each subsequent pressing of the key moves one to the next element in the list. Within
tables you will get to the next field. Pressing the key while keeping the <Shift> key depressed
selects the previous element.
• The arrow keys can be used to change from a selected element to a neighbouring one in any
direction.
• The <Space bar> is used to execute an activity on the selected visualization element. If the
element is one which has a text output variable or if it is a table field, a text input field will be
opened which displays the text contents of the variable resp. the field. Pressing the <Enter> key
writes in this value.
Additional key (combinations) for the online operation can be defined in the configuration dialog
'Keyboard usage'. There also the keys <Tab>, <Space> and <Enter> can get assigned another
functions than the above described standards.
The individual elements of instances behave in Online mode identically to the corresponding ones in
the visualization that is instanced. They will therefore react the same way as individual elements to
inputs and operation by mouse and keyboard; the display of tooltips in instances is also elementdependent. When processing the element list, as for instance when jumping from one input element to
the next using the tabulator, the processing of all individual elements of a instance proceeds from the
location of the instance in the element list before jumping to the next element of the list.
Note:
Operation over the keyboard in online mode is of greatest significance, if the visualization should be
used with CoDeSys HMI resp. as Target-Visualization or Web-Visualization !
'File' 'Print' in online mode
'File' 'Print'is used to print out the contents of the visualization window in online mode. Visualizations
which stretch over the border of the window can lead to inconsistencies particularly when there are
moving elements in the visualization.
2.9
Visualizations in libraries...
Visualizations can also be stored in libraries and thus be made available to projects in the form of
library POUs. They can be inserted as instances or they can be called up via the command „Zoom to
vis." in the input configuration of another visualization which is part of the project.
Note:
Visualizations used in a project must have unique names. It can cause errors if for instance a
visualization from a library is called or referenced which has the same name as one present in the
The CoDeSys Visualization
2-61
2 - The Visualization Editor in CoDeSys
project, because in processing instances or visualization calls in the program first the visualizations in
the project, and only thereafter the ones in the loaded libraries will be implemented.
2-62
The CoDeSys Visualization
3 - CoDeSys HMI
3
CoDeSys HMI
CoDeSys HMI is the run time system needed for the execution of the well known CoDeSys
visualisation. This system enables the user to create an inexpensive software for operating machines
and plants using the visualisations generated in CoDeSys.
CoDeSys HMI uses the already existent project file for the visualisation. Of course it is possible to
protect the application program with a read-only protection. The masks then appear in the full-picture
mode and merely the visualisation starting with the picture “PLC_VISU” is shown. All the other
operational elements of CoDeSys like menus or the object organiser are not visible.
By seamlessly integrating the development platform for the visualisation masks into the PLC
programming system CoDeSys HMI offers advantages other visualisations simply cannot come up to:
• A tag list of the variables to be used is not needed. It is possible to work directly with the CoDeSys
variables.
• Variable values in input fields can be modified by expressions (e.g. “Variable1+ Variable2 * 12 +
5”)
• A mighty place-holder concept allows the user to create object-oriented masks. This means the
user can build modules similar to the CoDeSys function blocks in the visualisation.
The CoDeSys functions “Sampling Trace“ and “read/write recipe“ are also available in CoDeSys HMI.
3.1
Installation, Start and Operating
CoDeSys HMI can be installed with the standard CoDeSys setup. If no valid license is available, a
time-limited demo version can be used.
CoDeSys HMI (CoDeSysHMI.exe) is started by a command line:
In each case at least the desired CoDeSys project has to be given in the command line. If no further
parameters are set there, CoDeSys HMI automatically will start with a visualization POU named
PLC_VISU (if existent in the project) and on that target or simulation mode, which was set when the
project had been saved last.
Additionally as well the known command line and command file commands (see User Manual for
CoDeSys) as the following special parameters can be used:
"/simulation" resp. "/target"
Per default it will be started in that mode which was set when the
project was saved last. Using the parameter "/simulation" resp.
"/target" in the command line it can be set explicitly whether the
project should run in simulation mode or on the target.
/visu <visualization POU>
If the project contains a visualization POU named PLC_VISU, it
will start automatically with this one. If another POU should be the
entrance, it has to be set in the command line with "/visu <name
of visualization POU>".
/visudownload
Overrides the download lock:
If the user tries to log in with a project, which is different to that on
the PLC, per default a download of the new project (dialog) can
be initiated. If however there is an entry "visudownload=no" in the
codesys.ini file, then no download is possible. This lock can be
overridden by the command line parameter "/visudownload".
/visucompactload
This parameter can be used for optimization at starting a project
for which no download
is required. If a download gets necessary anyway, e.g. effected by
parameter "/visudownload",
"/visucompactload" will be ignored.
The CoDeSys Visualization
3-1
3 - CoDeSys HMI
Example for a command line:
D:\PROGRAMME\CoDeSysHMI /simulation D:\PROJECTS\PROJECT.PRO /visu overview
The project project.pro will start in simulation mode and with the visualization POU 'overview'.
Please regard: Paths containing spaces must be bordered by quotation marks (").
The project will start in full screen mode with the entrance POU.
CoDeSys HMI can be operated corresponding to the functions of the visualization elements via
keyboard and mouse.
If there is no visualization element configured with a corresponding function, CoDeSys HMI at any
time can be terminated by pressing <Alt><F4>.

The CoDeSys Visualization
4 - Web-Visualization
4
Web-Visualization
The Web-Visualization is a target specific application of a CoDeSys visualization.
CoDeSys can create XML descriptions of the visualization objects and download them to the PLC.
There a Web-Server will provide the PLC data in XML format too and thus can create a continuously
updated visualization which can be opened in the Web Browser of any computer which is connected
via Internet, independently from the target platform (e.g. useful for remote maintenance purposes).
Please regard: Due to the low tranfer rates of the Internet only about 100 variables per visualization window can
be monitored.
4.1
Preconditions
• the target system must support the functionality; that means that in the target settings the option
'Web-Visualization' must be activated. If defined in the target file, this can be done by the user in
the 'General' target settings.
• A WebServer must be started. (see below)
• In order to get the Web-Visualization displayed on a computer, a Web-Browser (IE-Explorer or
Netscape) is required.
• Operating system: Windows NT/2000, Windows CE, Linux, RTE
4.2
Editing the WebVisu.htm file
During CoDeSys installation the file WebVisu.htm (base-HTML-page for the Web-Visualization) gets
copied to the subdirectory "visu" in the installation directory. The page can get edited there, before it
gets downloaded to the target system together with the Web-Visualization project:
If webvisu.htm is opened in a text editor, it shows the following structure:
<HTML>
<HEAD>
<TITLE>Applet HTML Page</TITLE>
</HEAD>
<BODY>
The CoDeSys Visualization

4 - Web-Visualization
<APPLET
CODEBASE=.
CODE=webvisu/WebVisu.class
name="WebVisu" width="1600" height="1200">

<param name="UPDATETIME" value="100">
<param name="USECURRENTVISU" value="FALSE">
</APPLET>
</BODY>
</HTML>
The following parameters can be set to control the behaviour of the Web-Visualization:
• STARTVISU - Definition of the start POU (Default: PLC_VISU)
• UPDATETIME - Definition of the monitoring interval (msec)
• USECURRENTVISU - Definition whether an automatic change to another visualization will be
done, as soon as the system variable 'CurrentVisu' is changed by the PLC program. (For
information on implicit variables see Appendix A.)
• The parameters „width“ and „height“ define the size of the screen (Regard the possibility to make
visible this size already during creating a visualization in CoDeSys).
4.3
Preparing a Web-Visualization in CoDeSys
• Create the visualization(s) for your PLC program as usual in the CoDeSys programming system. If
you want a certain visualization to be called as starting object, then name it 'PLC_VISU'. It will be
loaded automatically as soon as the visualization is called via the Internet.
• For visualization objects, which should not be part of the web version of the visualization,
deactivate option Web-Visualization' in the dialog 'Object' 'Properties' in category 'Visualization'.
• Perform command 'Project' 'Clean all', then 'Project' 'Build'.
• Log in to the target system ('Project' 'Online' 'Login') and start the project on the PLC.
4.4
Configuration and Start of the Web Server
• The WebServer must be available as an appropriate executable file (*.exe) for the used target
system.
• The configuration of the server can be done by a configuration file or by parameters added in the
command line when calling the server-exe. The definitions given by a configuration file will
overwrite those of the command line.
The possible parameters:
4-2
webserver-port-nr
Port, on which the WebServer expects
requests of the client (Web-Browser)
Default: 80
target-port-nr
Port of the runtime system
Default: 1200
target-ip-address
IP-Address of the runtime system
Default: localhost
use-file-upload-dir
If this flag is set to TRUE, additionally
the file-upload-directory (see below, fileupload-dir) must be defined, where the
*.xml, *.bmp, *.jpg, etc. files of the
Web-Visualization are stored on the
target system and from where they are
uploaded to the browser.
Default: false
file-upload-dir
Directory for the Web-Visualization files
Default:“”
The CoDeSys Visualization
4 - Web-Visualization
Please regard: If you define a "file-upload" directory, where the controller can store the visualization download
files, then the visualization files will be automatically updated at each download. The advantage of
this upload-directory is that the controller is not involved and thus not strained. The Web Server gets
the files directly from the directory and by this the data transfer is much quicker. This is especially of
impact in case of a big amount of data.
A configuration file for the Web Server must be available in XML-format and it must be named
"webserver_conf.xml". It must be found in the directory where the webserver-exe is. If no
configuration file is available, the above mentioned default settings will be used (if not changed by
parameters added to the call of the server in a command line.)
An example configuration in the webserver_conf.xml file could look as follows:
<webserver-configuration>
<webserver-port-nr> 8080 </webserver-port-nr>
<target-port-nr> 1200 </target-port-nr>
<target-ip-address> localhost </target-ip-address>
<use-file-upload-dir> true </use-file-upload-dir>
<file-upload-dir> C:\Programme\CoDeSysV23 </file-upload-dir>
</webserver-configuration>
A call in a command line must use the following syntax:
WebServer [webserver-Port-nr] [target-port-nr] [target-IP-address] | [file-uploaddir]
Thus a call corresponding to the above shown configuration example would look like follows:
> webserver 8080 1200 localhost c:\Programme\CoDeSysV23
Please regard: The parameter settings in the command line are without any effect, if there is a valid configuration
file available.
4.5
Calling a Web-Visualization via Internet
• Insert the following address in the Browser:
http://<IP-Adresse of the WebServer>:<Port of the WebServer>/webvisu.htm
• WebVisu is the default HTML-file. It contains a <applet> tag which will start the WebVisu-Applet

Target-Visualization
The Target-Visualization is one of the possible ways to use a CoDeSys Visualization. CoDeSys can
create ST code (Structured Text) for the visualization objects of a project. This code can be
downloaded to the PLC together with the normal project code.
Thus, if it is supported by the target system and if an appropriate monitor is available, the visualization
can be started directly on the PLC computer. It is not necessary any longer that the programming
system is running in order to run the visualization. This means a considerable reduction of storage
use.
5.1
Preconditions
• The target system must support the functionality; that means that in the target settings the option
'Target-Visualization' must be activated. If defined in the target file, this can be done by the user in
the 'General' target settings.
• The library SysLibTargetVisu.lib (external) is required for implementing the visualization functions
in the runtime system. It will be linked to the project as soon as the option 'Target-Visualization' is
activated in the target settings. In the runtime system the SysLibTargetVisu.lib also must be
implemented. Regard that also the following, implicitly used libraries will be loaded automatically as
soon as the option 'Target-Visualization' is activated: SysLibAlarmTrend.lib, SysLibSockets.lib,
SysLibFile.lib, SysLibTime.lib, SysLibMem.lib.)
• Operating system of the PLC computer: Windows NT/2000, Windows CE
• The PLC computer needs devices for displaying and operating the visualization (monitor, keyboard
etc.)
5.2
Creating a Target-Visualization
1. Create a visualization in CoDeSys. In order to optimize the performance of the visualization, put as
many elements, which are static (no movement, no dynamic texts, no dynamic color changes), to
the back. Hint: Using 'Extras' 'Elementlist' several or all elements can be "Sent to back" or "Sent to
front" in a single blow. (Explanation: All static elements only once will be drawn to a background
bitmap. Thus the cyclic repaint time will be reduced. This will be profitable especially for complex
polygons or bitmaps.)
If there is a visualization object PLC_VISU, the Target-Visualization later will be started with this
object. Otherwise it will start with that object which is the first one in the list of visualization objects
in the Object Organizer.
Please regard: For target computers running with Windows NT/2000, Windows CE the bitmaps of the
visualization will be transferred as files.
2. For each visualization object, which should not be part of the Target-Visualization, deactivate the
option 'Target-Visualization' in the Object Properties dialog ('Project' 'Object' 'Properties') in
category 'Visualization'.
3. Make sure that the option 'Optimized jumps' is deactivated in the target settings (Target Platform).
4. In the Target Settings in tab 'Visualization' (it depends on the target system, whether the particular
options are available in this dialog!) configure that the project should be prepared for use in the
Target Visualization: Activate option Target visualization.
Additionally here you can define whether the user inputs and the re-painting of the visualization
elements....
... should be controlled via VISU-tasks which are generated automatically or via individual
programming: Activate option 'Deactivate task generation'.
... should be processed by one or by two POUs resp. tasks: Activate option 'Use
VISU_INPUT_TASK'. (Don't get irritated by the term "..._TASK" in this case; this option is also of
effect if no VISU_INPUT_TASK is generated. Please see the descriptions in the following table.)
The CoDeSys Visualization
5-1
5 - Target-Visualization
Thus the following configurations are possible:
(a) The Target visualization is controlled by VISU-tasks which are generated automatically and which
call the POUs MAINTARGETVISU_PAINT_CODE and MAINTTARGETVISU_INPUT_CODE:
Deactivate task generation is switched off:
(a1)
Use VISU_INPUT_TASK is activated:
Automatically two tasks will be generated,
each calling a program:
• VISU_TASK calls the implicitly available
POU
MAINTARGETVISU_PAINT_CODE,
which does the repainting of the
visualization elements.
• VISU_INPUT_TASK calls the implicitly
available
POU
MAINTARGETVISU_INPUT_CODE,
which does the processing of the user
inputs.
The default settings of the tasks:
- VISU_INPUT_TASK: cyclic, priority 14,
interval t#200ms.
- VISU_TASK: cyclic, priority 15, interval
t#50ms.
Of course the parameters can be modified.
But: VISU_INPUT_TASK always should be
processed before VISU_TASK in order to
guarantee a useful interaction of user inputs
and update of the visualization. The task
calling the main program (e.g. PLC_PRG),
should at least be processed as often as
VISU_INPUT_TASK, ideally even with a
higher priority, but it also could be added
directly to VISU_INPUT_TASK.
(a2)
Use VISU_INPUT_TASK is deactivated:
Only task VISU_TASK will be generated
automatically, but in this case will include the
functionality of VISU_INPUT_TASK. The
implicit program POU MAINTARGETVISU_
PAINT_CODE in this case additionally will
include the
functionality of program
MAINTTARGETVISU_INPUT_CODE.
This configuration is intended for systems
which
do
not
allow
multi-tasking.
Disadvantageously no differentiated cycle
times can be configured for the processing of
user inputs and the repainting of the
visualization elements, see above.
(b) The Target visualization is not controlled by automatically created tasks; the implicitly available
POUs MAINTARGETVISU_PAINT_CODE and MAINTTARGETVISU_INPUT_CODE can be
called by the application program resp. can be appended to any task: Deactivate task generation
is activated:
5-2
The CoDeSys Visualization
5 - Target-Visualization
If additionally option Use VISU_INPUT_TASK
is activated, both implicit POUs are available
and can be called individually resp. can be
appended to any task. (Referring to this
regard the hints in (a1).
(b1)
n:=n+1;
IF n=(n MOD 4) THEN
MAINTARGETVISU_INPUT_CODE();
END_IF;
MAINTARGETVISU_PAINT_CODE();
Example for calls of the Target-Visulization
POUs in the application program: Here in
program visu_control the POU which
processes the user inputs is only called after
each fourth call of the repainting POU - thus
reducing the danger of getting disturbed the
repainting by another user input.
When creating the application program,
absolutely pay attention to reduce this
danger of incorrect display !
Example for use of any desired task for
controlling the Target visualization POUs;
here the above shown program visu_control
is called by task visu.
If option Use VISU_INPUT_TASK is not
activated, only the implicitly available
program
POU
MAINTARGET
VISU_PAINT_CODE can be used, but in
this case it will additionally include the
functionality of MAINTARGET VISU
_INPUT_CODE.
This POU can be called in the application
program resp. can be appended to any
task.
5. Load the project into the controller ('Online' 'Login')
5.3
Starting the Target-Visualization
Start the loaded project on the PLC. Hereupon the visualization will start with the PLC_VISU object
resp. – if no PLC_VISU is available – with that visualization object which is the first one in the list of
visualization objects in the Object Organizer.

Example Dll for ActiveX Control
See in the following an example of a source file of a Dll used for an ActiveX-Element in the CoDeSys
visualization.
This sample dll will only call the methods GoBack or GoForward of the control if this supports the
IWebBrowser interface (see Chapter 2.4.1, ActiveX-Element).
The method is chosen by the parameter pszId.
#include "stdafx.h"
#include <unknwn.h>
#include <exdisp.h>
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
return TRUE;
}
extern "C" __declspec (dllexport) void ExecuteActiveXCall(IUnknown* pUnk,
char* pszId, char* pszParam, char* pszReturnBuffer, int nReturnBufferSize,
DWORD* pdwReturnFlag)
{
if (strcmp(pszId, "IWebBrowser|GoBack") == 0)
{
IUnknown* pNewUnk;
IWebBrowser* pwb;
pUnk->QueryInterface(IID_IWebBrowser, (void**) &pNewUnk);
pwb = (IWebBrowser*) pNewUnk;
if (pwb)
{
pwb->GoBack();
pwb->Release();
}
}
else if (strcmp(pszId, "IWebBrowser|GoForward") == 0)
{
IUnknown* pNewUnk;
IWebBrowser* pwb;
pUnk->QueryInterface(IID_IWebBrowser, (void**) &pNewUnk);
pwb = (IWebBrowser*) pNewUnk;
if (pwb)
{
pwb->GoForward();
pwb->Release();
}
