logi.CAD 3 evaluates a dynamic text depending on the element to which the →comment field has been attached. Hence, let logi.CAD 3 evaluate certain information.

The following dynamic texts are supported:

Dynamic text

Meaning

{comment}

if the comment field is attached to a value field containing a variable: comment of the variable

{dataType}

→data type of the →variable or the →function block type

{instanceData("element", "parameter/text")}

instance data for →function block instance
Instance data elements are additional data elements for the function block. Usually, such instance data elements exist only for function blocks within a library provided by a system integrator. If you want to enter/define such instance data elements for a block within the graphical user interface of logi.CAD 3, you require a logi.CAD 3 variant that has been enhanced by a system integrator.

The following data is required within the dynamic text:

element: name of one instance data element; example: ActiveGroup

parameter/text: one or several of the following parameters – with or without plain text (see the following examples)

Parameter	Meaning
`%n` or `%name`	name of the instance data element; example: `ActiveGroup`
`%t` or `%type`	type of the instance data element; example: `STRING`
`%v` or `%value`	value of the instance data element; example: `Passive`

If you skip parameter/text , the dynamic text is evaluated as %v by default. If you want to quote text within parameter/text, use the single quote character '. The double quote character " is not supported within parameter/text.

Observe:

If the information is not available for an element, no corresponding text is displayed within the comment field.
The characters { and } are reserved for dynamic texts. If you want to display these characters within a comment field, prefix them with the character \.

Example for input

COLOR = \{blue, yellow, red\}

Examples of evaluating instance data

It is possible to enter a plain text outside and/or inside the dynamic text for the instance data. Use the method best suited for you.

Input within the comment field	Example of evaluation
Plain text outside the dynamic text `Group: {instanceData ("ActiveGroup")}`	`Group: MX2040`
Plain text inside the dynamic text `{instanceData ("ActiveGroup", "Group '%n' with value '%v'")}` or Plain text outside the dynamic text `Group '{instanceData ("ActiveGroup", "%n")}' with value '{instanceData ("ActiveGroup", "%v")}'`	`Group 'MX2040' with value 'Passive'`
Plain text inside the dynamic text `{instanceData("simplefield", "Instance data:` `Name: '%n',` `Value: '%v',` `Type: '%t'")}` or Plain text outside the dynamic text `Instance data:` `Name: '{instanceData("simplefield", "%n")}',` `Value: '{instanceData("simplefield", "%v")}',` `Type: '{instanceData("simplefield", "%t")}'`	`Instance data:` `Name: 'simplefield',` `Value: '1234',` `Type: 'INT'`
