====== Variable ======
The Variable can be used to either save header values of the I/O or create new variables. It can have different data types, e.g. Integer. Decimal, String. They are only valid within the [[eyes:logics:group|]] they are created in.

===== Usage =====
To construct a new Variable it is necessary to drag the element into a Group. In the properties window the type and name of the Variable is selected. It is possible to set a value and give a description. 

A logic properties field can access the Variable by a right click in the text field (line edit), where it is supposed to be inserted. Then by clicking on 'Set Variable' a new window opens, where the name is put in. Important to know is that there needs to be a $ before the name of the Variable.
