‘Extras’ ‘Configure’

With this command, the ‘Configure element’ dialog opens for configuring the selected visualization element (see Selecting Visualization Elements). You are given the dialog box when you double-click on the element.

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

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.

Note

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.

Note

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 ( Placeholder).
