Single-row text object. If no text is specified, in e.g. a Frame object, the object can be used to frame other objects. The only difference between Frame, Head, Text, and Title is the default values of the attributes.
They are used in Document objects where, for instance,
- Title specifies what the configuration is doing, i.e.
the function.
- Sub-functions are named by Head objects.
- Frame and Text are used to information of details.
HintsA well-done PLC program ought to contain not only objects necessary to the computer execution but also objects whose purpose are to make the program more easy to understand to later readers. See figure below.
Title, Head and Text Objects Make the Program Easy to Read.

| FrameAttrEnum | FrameAttribute | Specifies if the text is to be surrounded by a some kind of frame. |
|
| Float32 | FrameWidth | If the object has a frame the attributes will determine the size of the frame. 0, 0 means the size of the frame is accommodated to the current text. If the object is used only to frame other objects the attributes have to be increased in suitable way. |
