<group> Element

This element defines the symbol group to be created on the HMI page defined by the parent <page> element. The creation of the group is triggered by an IEC code element (for example, FB instance, program instance, etc.) defined by the descendant <on...> element such as <onfunctionblock>.

The child elements <groupstyle> and <dataset> are used to assign definitions referenced by the content of the elements to the created symbol group.
