Cross references
To create a reference to another element within the documentation, use the "$" character. If the reference target is not within the same code element, a qualified name, i.e. a full domain name, must be used. TwinCAT Documentation Generation automatically searches for this element and creates a hyperlink in the documentation. You use the cross-reference within the Description, Summary and Example markups.
Example
Normal form:
//!<description> You can find an example in $Codeblock
</description>
Abbreviated form:
//!@description You can find an example in $Codeblock
